Twins bypass Aaron Hicks for Eddie Rosario to replace Oswaldo Arcia

Eddie Rosario Twins

It's common for the Twins to cite a prospect's lack of "consistency" in the minors as an excuse for why they haven't been called up. Most recently they did so with Triple-A reliever Lester Oliveros, who has a 1.65 ERA and 109 strikeouts in 76 innings since last season. Sustained dominance like that makes the notion of Oliveros lacking "consistency" seem absurd, particularly compared to the low standards for "consistency" the Twins so often seem to have for mediocre veterans.

Another problem with the Twins citing a lack of "consistency" whenever it suits them is that when it doesn't suit them they're quick to ignore the concept. Right now, for instance. Needing outfield help with Oswaldo Arcia headed to the disabled list with a hip injury, the Twins called up Eddie Rosario from Triple-A to make his MLB debut at age 23. Rosario was hitting .242/.280/.379 with a 17/5 K/BB ratio in 23 games for Rochester, which is terrible.

And that's nearly identical to his terrible performance last year, when Rosario was suspended for the first 50 games following a positive drug test and returned to hit .237/.277/.396 with a 68/17 K/BB ratio in 79 games at Double-A. In between he was talked up by the Twins throughout spring training only to hit .233 with zero walks in 17 games. In retrospect the spring disconnect between the praise he received and his performance was foreshadowing.

Rosario was suspended 50 games for drug use and hit terribly at two levels of the minors and in spring training since returning, but "consistency" apparently isn't always a must for a call-up. For whatever reason the Twins and especially manager Paul Molitor are infatuated with Rosario and it's also clear they've totally soured on Aaron Hicks, himself a former top prospect who struggled in the majors after being handed an Opening Day job too soon and is still just 25 years old.

Hicks is hitting .289/.375/.494 with a 15/12 K/BB ratio in the same Rochester lineup as Rosario, topping him in every way except being on the Twins' good side. Hicks also hit .291/.387/.441 with a 40/37 K/BB ratio in 67 games between AA/AAA last season, easily out-performing Rosario again. And while Hicks has struggled for the Twins, he posted a .341 on-base percentage over 69 games in the majors last year while Rosario has failed to crack a .300 OBP in the minors since last year.

For the sake of simplicity, here's how their career Double-A and Triple-A numbers compare:

TRIPLE-A      AVG      OBP      SLG      OPS     K/BB
Hicks        .264     .349     .410     .759     1.58
Rosario      .242     .280     .379     .659     3.40

DOUBLE-A      AVG      OBP      SLG      OPS     K/BB
Hicks        .289     .389     .461     .850     1.31
Rosario      .260     .302     .403     .705     3.55

Hicks is also considered as good or better defensively than Rosario, who attempted to transition from center field to second base before going back to the outfield full time this season and has always been projected more as a corner outfielder due to limited range. It's hard to blame the Twins too much if they've indeed given up on Hicks, but there's no indication Rosario is ready for the majors and this move makes any "consistency" talk look even sillier than usual.

As for Arcia, this is another setback on his quest to gain the Twins' trust and establish himself as an everyday, middle-of-the-order bat. Molitor's willingness to platoon has put Arcia on the bench frequently versus lefties and both his plate discipline and defense remain huge weaknesses. He's hitting reasonably well at .276/.338/.379 in 19 games, but all four of Arcia's walks have been intentional and he's swung at the second-most pitches outside the strike zone in the league.

The art of platooning: Molitor vs. Gardenhire and Arcia vs. lefties

oswaldo arcia twins

Paul Molitor barely has his feet wet as Twins manager, but one noticeable change from Ron Gardenhire is the willingness to platoon. In his 13 seasons as manager Gardenhire essentially never platooned based on handedness, instead treating left-handed bats like Jacque Jones and Jason Kubel as everyday players despite their inability to handle left-handers and ignoring the potential value mediocre right-handed bats like Danny Valencia had as lefty mashers.

Molitor platooned more in his first couple weeks than Gardenhire did in some seasons, regularly benching Oswaldo Arcia and Jordan Schafer against lefties. That's a positive sign in the sense that platooning is a very straightforward, commonplace method of squeezing the most value out of non-stars and putting players in a position to succeed, but in this case the Twins constructed such a weak bench that their platoon options are pretty unappealing.

Not playing Schafer against lefties is a good idea, but Shane Robinson is such a weak overall hitter that his right-handedness barely makes a difference. Not playing Arcia against lefties is also a good idea, at least in the short term, but if the Twins still hold out any hope of him developing into an everyday player he'll need playing time versus lefties eventually and Eduardo Escobar, while better than Robinson, isn't exactly an ideal platoon-mate for a corner outfielder.

Mostly, though, it's just nice to see a manager willing to embrace a common, effective tactic after more than a decade of watching lefties flail away against left-handed pitching, potentially useful righties cast aside because they struggled in everyday roles, and batting orders remain unchanged regardless of the handedness of the opposing pitcher. And if the Twins' bench ever contains better options Molitor could do some interesting things with the lineup.

It'd be great to have nine everyday players and just trot them out in the same lineup spots no matter who was on the mound, but it's hard to find teams that wouldn't benefit from at least some platooning. Nearly every left-handed hitter in baseball history with a sizable track record has fared better against righties than lefties, often to an extreme degree. Because of that, with a lefty on the mound even good left-handed hitters are often worse than mediocre right-handed hitters.

For instance, Joe Mauer and Justin Morneau are MVP-winning left-handed bats and two of the best hitters in Twins history. However, looking strictly at production against left-handed pitching they both have a lower career OPS than mediocre right-handed hitters like J.J. Hardy, Delmon Young, and Trevor Plouffe. Having the platoon advantage makes a huge difference. Here are the career splits for the Twins' most-used left-handed hitters of the Gardenhire era:

CAREER OPS           vsR      vsL
Joe Mauer           .915     .749
Justin Morneau      .894     .705
Jason Kubel         .813     .676
Denard Span         .751     .726
Jacque Jones        .816     .628
Corey Koskie        .870     .707

On average those six left-handed hitters have an .843 OPS versus righties and a .699 OPS versus lefties for a collective decrease of 17 percent and everyone but Denard Span sees their OPS drop more than 125 points. Those decreases are larger than typical across MLB, but in general lefties tend to be 10-15 percent worse versus lefties. Of course, some lefty bats are good enough overall that they warrant keeping in the lineup against lefties even with the decreased production.

Put another way: Mauer's production against lefties drops 18 percent, but he's still decent with a .749 OPS. However, not many lefties are as good as Mauer overall and so most warrant benching at least semi-regularly. Gardenhire obviously didn't agree. Jones hit .230/.278/.350 off lefties, yet Gardenhire played him every day and kept him leading off. Kubel hit .233/.305/.375 off lefties, yet Gardenhire played him every day and kept him in the middle of the lineup. You get the idea.

It's possible that Arcia will improve versus lefties and/or become productive enough overall that he's worth playing every day and because he's still just 24 years old it's certainly worth investing some more time into finding out. More likely is that he's ultimately a platoon or quasi-platoon player, which is less a knock on Arcia specifically and more just the way things tend to go with good but not great left-handed hitters.

Considering his poor defense Arcia needs to put up big numbers to be worth having in the lineup at an offense-heavy position. So far he's hit .221/.262/.340 off lefties, which is 25 percent worse than his .249/.322/.489 line off righties. Even if Arcia gets better versus righties and turns that 25-percent drop versus lefties into, say, a 15-percent drop it shouldn't be all that hard for the Twins to find a random right-handed hitter capable of better against lefties.

Aaron Hicks, while hugely disappointing overall, has posted a .758 OPS off lefties in the majors and has always hit lefties much better than righties in the minors. Hicks may never develop into a quality regular, but he's already a quality platoon option. With a lefty on the mound he's a viable center fielder and/or better than Arcia offensively and defensively in left field. And that's the magic of platooning, which turns useless into useful by separating strengths from weaknesses.

Molitor has shown the mindset required to improve a lineup via platooning, but the Twins need to actually give him the pieces to make those moves worthwhile and a four-man bench of Robinson, Escobar, Chris Herrmann, and Eduardo Nunez doesn't qualify. Still, after 13 years of learning to view hitters strictly through Gardenhire's binary "everyday player or not" lenses it's refreshing to consider how open-minded managing might take better advantage of useful but flawed options.

Season preview: Are the Twins ready to stop losing?

Paul Molitor

Nearly everyone involved with the Twins, from players and new manager Paul Molitor to general manager Terry Ryan and owner Jim Pohlad, seems convinced the team is poised to take a big step forward. Nearly everyone not involved with the Twins, from national writers and Las Vegas oddsmakers to numbers-driven projection systems and cranky local bloggers, seems convinced the team is headed for another last-place finish and possibly a fifth straight 90-loss season.

Sports Illustrated picks the Twins for last place and 67 wins. ESPN.com picks the Twins for last place and 68 wins. Baseball Prospectus projects the Twins for last place and 71 wins. Bovada sets the Twins' over/under win total at 72.5. FanGraphs projects the Twins for last place and 74 wins. Grantland picks the Twins for last place and "under 75 wins." CBS Sports picks the Twins for last place. Yahoo Sports picks the Twins for last place. You get the idea.

Last year the Twins were 72-90. Then they fired Ron Gardenhire after 13 seasons as manager, handed out the largest free agent contract in team history to 32-year-old Ervin Santana at $55 million over four years, brought back Torii Hunter for a $10.5 million reunion at age 39, signed 33-year-old reliever Tim Stauffer for $2.2 million, and bypassed young talent in favor of veteran mediocrity for every roster spot up for grabs in spring training.

Those are all the moves of an organization that's sick of losing and also sick of their plummeting fan morale and season ticket sales. They spent big on veterans and further delayed the arrival of prospects, leading to an Opening Day roster with just four players who're 25 years old or younger in shortstop Danny Santana, left fielder Oswaldo Arcia, designated hitter Kennys Vargas, and Rule 5 pick J.R. Graham.

This is a rebuilding team in the sense that the Twins have been very bad and are still attempting to get back on track, but it's anything but a young team. Kyle Gibson is the youngest member of the starting rotation at 27. Graham is the only member of the seven-reliever bullpen under 30. Six of the nine starting position players are at least 28. In terms of their collective average ages, the rotation is 30, the bullpen is 31, and the lineup is 29.

When the reality of the Twins' organizational collapse finally sunk in around mid-2012 or so the idea was that they'd be back to contending by now, but injuries ruined those plans. Joe Mauer's concussion derailed his career and turned him from a Hall of Fame-caliber catcher to a mediocre first baseman. Instead of making their MLB debuts Miguel Sano missed all of last year following elbow surgery and Byron Buxton missed all but 31 games with a wrist injury and a concussion.

Buxton and Sano will begin this season as teammates at Double-A, the Twins sent 25-year-old pitching prospects Alex Meyer, Trevor May, and Michael Tonkin back to Triple-A rather than trust them with roster spots that went to Tommy Milone, Mike Pelfrey, and Blaine Boyer, and after back-to-back Opening Day starts in center field Aaron Hicks is back in Rochester too. Toss in Arcia's development stagnating a bit and it's easy to see where the rebuild sputtered.

The good news is Buxton and Sano remain superstar-caliber prospects, Meyer and May still have enough upside to project as impact pitchers in some role, and there's another wave of prospects coming soon led by Jose Berrios, Jorge Polanco, and Nick Burdi. The bad news is none of that figures to actually help the Twins win many games before the All-Star break. Sadly, being a Twins fan in 2015 is still more about waiting for help to arrive than watching it play at Target Field.

Brian Dozier; Danny Santana

There's a lot of optimism surrounding the Twins' offense after the lineup produced the fifth-most runs in the American League last season, but building on or even duplicating that performance is hardly a sure thing. For starters, Santana was the only hitter on the team to crack an .800 OPS last season, coming out of nowhere to hit .319/.353/.473 as a rookie after batting .273/.314/.388 in the minors while failing to top a .725 OPS at Single-A, Double-A, or Triple-A.

Santana is good enough, young enough, and skilled enough to buy into reevaluating his upside compared to what his minor-league track record suggested, but his rookie success was still driven by an unsustainable .405 batting average on balls in play and came despite an ugly 98/19 K/BB ratio. The combination of a so-so track record, poor plate discipline, and a high batting average on balls in play makes him a prime regression candidate.

Brian Dozier also needs to fight his track record to show his 2014 was for real, albeit to a lesser extent than Santana. He was the Twins' best all-around position player, hitting .245/.345/.416 with 23 homers, 21 steals, 89 walks, and solid defense to rank among the top half-dozen second basemen in MLB. Clearly the Twins buy into Dozier's age-27 breakout, but prior to 2014 he hit just .240/.297/.384 in the majors and .232/.286/.337 at Triple-A.

Kurt Suzuki was another source of unexpectedly strong offense, hitting .288/.345/.383 to make his first All-Star team at age 30. As with Dozier the Twins bought into his resurgence with a new contract, but Suzuki hit .253/.313/.362 in the second half to resemble his measly .237/.294/.357 line from 2010-2013. Jordan Schafer's track record strongly suggests he'll be unable to repeat his 41-game Twins showing and Hunter is fighting father time at age 39.

All of which isn't to say the lineup lacks the ability to improve in spots. Mauer getting back to his usual self would be huge and he hit .300 with a .400 on-base percentage in his final 55 games. Arcia should take a step forward at age 24 and is capable of breaking out with a better approach. But for the most part more hitters are likely to decline than improve, some by wide margins. Of course, Buxton and Sano showing up in May or June ready to thrive could change everything.

Then there's defense, which has played an overlooked part in the Twins' struggles as the focus tends to be on the "pitching" rather than the run prevention of pitching plus defense. Combined from 2011-2014 the Twins ranked 28th in Ultimate Zone Rating at 90 runs below average and 24th in Defensive Runs Saved at 115 runs below average. They've been horrendous, especially in the outfield, which is doubly bad combined with fly-ball, strikeout-phobic pitching staffs.

Infield defense may not be bad because Dozier is solid at second base, Santana has the skills to be a plus shortstop, Trevor Plouffe showed big improvement at third base, and Mauer is fine at first base. However, the outfield is guaranteed to be a major weakness again. Arcia and Hunter were two of MLB's worst defensive corner outfielders last year and it's asking a lot of Schafer (or Hicks) to cover up their mess when he's actually gotten below average marks in center field.

Phil Hughes Twins

Last offseason the Twins gave a four-year, $49 million deal to Ricky Nolasco and a three-year, $24 million contract to Phil Hughes, and this offseason they took the uncharacteristic pursuit of free agent pitching even further by signing Santana for $55 million. Hughes got three years and $42 million tacked on to his previous deal following a breakout 2014 season and the Twins have Pelfrey and Milone under contract for a combined $8.5 million in 2015.

That's a lot of resources devoted to veteran starters and there's also a hidden cost that comes with having pitchers with guaranteed salaries locked into rotation spots that might otherwise be handed over to prospects. Hughes is signed through 2019, Santana is signed through 2018, Nolasco is signed through 2017, and even though Pelfrey and Milone aren't signed beyond this season the Twins were still hesitant to push them aside.

Hughes was a tremendous find on what was a very reasonable free agent contract that the Twins turned into a much bigger commitment. He logged 210 innings and pitched even better than his solid 3.52 ERA, striking out 186 and walking 16 for the best strikeout-to-walk ratio in the history of baseball. Asking for a repeat of that performance is wishful thinking, but Hughes seemed like a truly different pitcher last season and enters this year as a clear-cut No. 1 starter.

Santana was signed to take over the No. 2 spot and what he lacks in upside he makes up for in durability, although he's probably more of a No. 3 starter on a contending team. Nolasco looked like a No. 3 starter when the Twins gave him $49 million last offseason, but then pitched horribly for several months before revealing he was hurt and is now a question mark the Twins no doubt regret signing.

Gibson is the lone homegrown pitcher in the rotation and the former top prospect finally broke through last season to throw 179 innings in 31 starts. He was wildly inconsistent, but the end result was a 4.47 ERA in a league where the average starter was below 4.00. Inducing lots of ground balls helps Gibson make up for a lack of missed bats, but at age 27 and with just 5.4 strikeouts per nine innings his upside looks limited to the back of the rotation.

Milone beat out Pelfrey and May for the fifth spot and the soft-tossing left-hander will try to show that his awful post-trade performance for the Twins was due to a benign tumor in his neck that required surgery. Milone was a solid back-of-the-rotation starter for the A's, but Oakland's pitcher-friendly ballpark overstated his effectiveness and helped compensate for a mid-80s fastball. He has a 4.80 career ERA in non-Oakland ballparks.

If the goal was to put together a rotation less likely to be a disaster than the 2011-2014 versions the Twins absolutely accomplished that, but the price tags indicate they have much higher hopes and that may be pushing things. This is the worst rotation in the AL Central even if it's assumed Hughes will avoid turning back into a pumpkin and there isn't much upside unless Meyer and/or May hit the ground running soon. And compared to the bullpen the rotation is a strength.

Glen Perkins was one of the elite relievers in baseball for 3.5 seasons before melting down late last year while pitching through an injury. The bullpen desperately needs him to be his pre-injury self or things could get very ugly. Casey Fien is the primary setup man. Brian Duensing, who was a non-tender candidate, is the only lefty. Stauffer and Boyer have prominent roles and the Twins are hoping Pelfrey's one-pitch arsenal fits better in relief. It's an underwhelming group.


This should be the least-awful Twins team since 2010, but that's not saying much and confidence in even that mild statement dropped when they stacked the roster with Pelfrey, Milone, Duensing, Boyer, Schafer, Stauffer, Shane Robinson, Chris Herrmann, and Eduardo Nunez. That's a lot of self-imposed dreck for a team with better, younger options and there's a depressingly strong chance the same "are the Twins ready to stop losing?" question can be asked 365 days from now.

Twins Notes: Hughes, Perkins, Vargas, Liriano, Worley, and Arcia

Phil Hughes Twins

• With one start remaining Phil Hughes has an incredible 181-to-16 strikeout-to-walk ratio in 202 innings. Not only is that by far the best strikeout-to-walk ratio in baseball this season, it's the best strikeout-to-walk ratio in baseball history among all pitchers with 150 or more innings:

                    YEAR     SO/BB
PHIL HUGHES         2014     11.31
Bret Saberhagen     1994     11.00
Cliff Lee           2010     10.28
Curt Schilling      2002      9.58
Pedro Martinez      2000      8.88
Greg Maddux         1997      8.85
Pedro Martinez      1999      8.46

That's a helluva list to sit atop.

Hughes is 15-10 with a 3.61 ERA in 31 starts. The rest of the Twins' rotation is 31-58 with a 5.60 ERA in 126 starts.

UPDATE: The good news is Hughes finished his final start with the all-time K/BB ratio record intact. The bad news is thanks to an ill-timed rain delay he might finish one out short of $500,000.

Glen Perkins tried to pitch through what was initially believed to be a minor neck injury, but after several bad outings in which he clearly wasn't right physically the Twins sent him for more testing. He was then shut down after being diagnosed with what they're calling a forearm strain and nerve irritation. It's unfortunate, because not only does Perkins head into the offseason as a question mark, his attempts to pitch through the injury ruined his strong season totals.

As of August 25 he had a 2.44 ERA and 64/9 K/BB ratio in 55 innings, but then Perkins allowed 10 runs in 6.1 innings to inflate his ERA to 3.65. During that span he gave up five home runs in eight games after giving up a total of seven home runs in his previous 116 games since the start of last year. Everyone acts like playing through injury is to be commended, but it usually goes badly for player and team. Perkins says he learned his lesson about "trying to be a tough guy."

Kennys Vargas and Jose Berrios were named the Twins' minor league player and pitcher of the year. Vargas hit .281/.360/.472 with 17 homers in 97 games at Double-A as a 23-year-old before being called up to the majors on August 1. Berrios split his age-20 season between high Single-A and Double-A--with a late cameo at Triple-A--posting a 2.76 ERA and 140/38 K/BB ratio in 140 total innings. Last season's winners were Byron Buxton and Andrew Albers.

• Vargas' early success for the Twins has been hugely fun to watch, although his horrific 58-to-4 strikeout-to-walk ratio through 48 games is a massive red flag and surprising considering his solid walk rates in the minors. Vargas was handed the cleanup spot after one week in the majors, which is very rare in Twins history. In fact, here's a list of Twins with the most starts in the cleanup spot through 48 career games:

KENNYS VARGAS     44
Kent Hrbek        20
David Ortiz       19
Justin Morneau    16
Todd Walker       14
Chris Parmelee    13
Tom Brunansky     12

Vargas also has nine homers through 48 games, which is tied with Kent Hrbek, Gary Gaetti, and Josmil Pinto for the third-most behind Marty Cordova and Tom Brunansky with 10 apiece.

Francisco Liriano is in the midst of a 28-inning scoreless streak and now has a 3.32 ERA with 170 strikeouts in 157 innings for the Pirates after posting a 3.02 ERA with 163 strikeouts in 161 innings for the Pirates last season. His rotation-mate, Vance Worley, has a 2.93 ERA and 75/22 K/BB ratio in 104 innings. Add it all up and Pittsburgh has gotten 417 innings of a 3.15 ERA from Liriano and Worley for less than the Twins paid Mike Pelfrey.

Terry Ryan brushed off questions about Worley's turnaround in June, saying:

Give him a little time to see what he does over the course of starts. We'll talk about that in October. See how it goes.

Well, it's almost October. Also, just a reminder: Before selling Worley to the Pirates at the end of spring training the Twins sent him outright to Triple-A, which means they could have stashed him there all season without even taking up a 40-man roster spot. They gave him away for no reason other than they were convinced he had zero value. Worley, still just 26 years old, now has a 3.35 ERA in 382 career innings for non-Twins teams. And even Carlos Gomez is impressed.

Oswaldo Arcia has the seventh-highest Isolated Power in Twins history among all hitters with 750 or more plate appearances:

Harmon Killebrew     .258
Don Mincher          .239
Bob Allison          .225
Josh Willingham      .214
Jimmie Hall          .212
Justin Morneau       .207
OSWALDO ARCIA        .202
Tom Brunansky        .202
Kent Hrbek           .199
Torii Hunter         .198
David Ortiz          .195

Arcia has 33 homers, which is the fourth-most in Twins history through age 23 behind Brunansky (80), Hrbek (40), and Zoilo Versalles (34). He can't control the strike zone, can't hit lefties, and can't catch much in the outfield, but Arcia's power potential is special. And on the subject of his terrible defense, here's a fun little tidbit: Arcia played 77 games in center field as a minor leaguer, including some at Double-A. Think about that.

• Ultimate Zone Rating calculates the Twins' defense has been 85 runs below average since 2011, including -48 for the infield and -37 for the outfield. Obviously the Twins' pitching has been awful, but if you take awful, low-strikeout pitching and put awful defense behind it you have no chance.

• Post-trade performances: Josh Willingham has hit .243/.361/.400 in 23 games for the Royals to almost exactly match his .210/.345/.402 line in 68 games for the Twins. Sam Fuld came back down to earth, hitting .211/.270/.320 in 48 games for the A's. Kendrys Morales has continued to be terrible, hitting .206/.274/.335 in 53 games for the Mariners. Kevin Correia has continued to be Kevin Correia, posting an 8.03 ERA in 25 innings for the Dodgers.

And since the Twins decided not to trade him and gave him a two-year contract extension instead, Kurt Suzuki has hit .256/.291/.383 with a 15/3 K/BB ratio in 37 games.

Pedro Florimon, who began this season as the Opening Day shortstop, was claimed off waivers by the Nationals when the Twins took him off the 40-man roster. He's a good defensive shortstop, but Florimon hit .205/.266/.300 in 210 games for the Twins. The only players in the history of the Twins to log more appearances with a lower OPS than Florimon are Jerry Zimmerman and Jim Kaat. Kaat was a pitcher.

• Across baseball this season there have been more than 1,700 games started by pitchers younger than Kyle Gibson. He might be inexperienced and he might be inconsistent, but he's not young.

• By my calculations the Twins have as many as 19 players on the 40-man roster they could cut, although my guess is that they'll keep half of them.

• It's official now: If the Twins don't fire Ron Gardenhire he'll be just the third manager in the history of baseball to keep his job following four consecutive 90-loss seasons.

• Last time the Twins won 90 games in back-to-back seasons was 2003/2004. Since then they have a 789-828 record for a .488 winning percentage.

Oswaldo Arcia, lefties on lefties, and swinging “too hard”

oswaldo arcia twins

After a promising rookie campaign last year Oswaldo Arcia has been a mess for most of this season, hitting .199 with 56 strikeouts in 44 games since homering in back-to-back games in early June. He's been particularly helpless versus left-handed pitching, hitting .180 with 24 strikeouts in 68 plate appearances for the season, and Ron Gardenhire recently got Arcia's struggles against southpaws some media coverage by discussing them with reporters:

Not good. Hasn't been good. He missed some fastballs [Friday] night. He had two to hit. He's just got to put the barrel on them. He's got to hit them. The first one was right there, and he just fouled it off. He's just trying to hit the ball 8,000 miles right now. Every swing he takes, he swings so frickin' hard that I don't know any way possible that your head can be on the ball. ... He's got to get away from that. He's not going to hit at this level if he continues to swing as hard as he possibly can, trying to hit the ball 8,000 miles.

I'm certainly in no position to say whether those criticisms are legitimate and/or helpful, but I will note that the Twins had similar and similarly public "swings too hard" criticisms of Carlos Gomez and, before him, David Ortiz. I'll also note that Arcia is hardly the first young left-handed hitter to flail away against left-handed pitching. Through age 23 he's hit .229 with a .625 OPS versus lefties. Here's how that compares to some other left-handed Twins hitters at the same age:

vs. LHP                PA      AVG      OPS
OSWALDO ARCIA         185     .229     .625
Justin Morneau        110     .218     .630
Joe Mauer             398     .275     .671
Rod Carew             178     .286     .704
David Ortiz            78     .234     .734

Arcia is a rarity in Twins history simply by being in the majors and accumulating regular playing time versus left-handed pitching at age 23. In fact, only 11 left-handed hitters in franchise history have at least 50 plate appearances versus lefties through age 23. I've included four of the most prominent names on that list in the above comparison with Arcia. He has the worst production of the bunch, but Justin Morneau was almost exactly as unproductive and no one was very good.

Joe Mauer and Rod Carew hit for solid batting averages off lefties, because that's just what they were born to do, but they both had modest overall production and extreme platoon splits. And that's simply how it goes with left-handed hitters. Most of them struggle against lefties initially and many of them never really learn to hold their own against them. For instance, Jacque Jones hit .227 with a .616 OPS off lefties for his entire Twins career, totaling 848 plate appearances.

In other words, for his seven Twins seasons Jones was as terrible against lefties as Arcia has been through age 23. Gardenhire used Jones as an everyday player nearly that entire time, refusing to platoon him and often starting him in the leadoff spot versus lefties. Perhaps he didn't "swing too hard," but Jones was helpless versus lefties too and Gardenhire stubbornly never let that change his strategy and the Twins' coaching staff never helped him get any better.

Want more examples? No left-handed hitter in the history of the Twins with more than 200 plate appearances against left-handed pitching has ever topped an .800 OPS off them. And among that group only Carew, Ortiz, Doug Mientkiewicz, Denard Span, Kent Hrbek, and Matt Lawton topped .750. Here are some of the bigger names who struggled against left-handed pitching while in a Twins uniform:

vs. LHP              OPS
Jimmie Hall         .564
Jacque Jones        .616
A.J. Pierzynski     .647
Jason Kubel         .673
Tony Oliva          .690
Justin Morneau      .711
Corey Koskie        .725

Morneau won an MVP award and is one of the best half-dozen hitters in Twins history, but he hit just .251 with a .298 on-base percentage and .414 slugging percentage off lefties. Tony Oliva is a borderline Hall of Famer, but he had a lower OPS against lefties than thoroughly mediocre right-handed hitters like Brendan Harris, Steve Lombardozzi, and Dustan Mohr. Going beyond the Twins, across all of MLB this season lefty hitters have a .649 OPS off lefty pitchers.

My point isn't that Arcia ought to stick with his approach versus lefties. It also didn't work in the minors, where he hit .265 off lefties compared to .330 off righties. He absolutely needs to improve against them in order to fulfill his potential and hopefully Twins coaches can help him. However, the fact that he's struggling with lefties so far isn't necessarily some sort of character flaw and it may not mean anything at all other than he happens to be a left-handed hitter.
