Twins Notes: Goin, Tosoni, Harden, Bullock, Diamond, and Liriano

Parker Hageman of Twins Daily interviewed Twins manager of major league administration and baseball research Jack Goin for a glimpse into the team's use of statistical analysis. Hageman co-hosted this week's "Gleeman and The Geek" episode and we discussed that topic quite a bit. Short version? While it's nice to see the Twins get more involved in statistical analysis my sense remains that they're merely dipping their toes in the water while other teams are swimming.

Rene Tosoni, who the Twins dropped from the 40-man roster in August, has signed with the Brewers on a minor-league contract. Tosoni cracked my annual ranking of Twins prospects at No. 11 in 2010 and No. 14 in 2011, but he was sidetracked by injuries and then basically just stopped hitting. Now he's a 26-year-old corner outfielder who struggled in 60 games for the Twins in 2011 and hit just .224/.293/.315 in 81 games between Double-A and Triple-A last season.

Clete Thomas, who briefly filled a bench spot while the Twins kept Ben Revere at Triple-A for a bit longer, has re-signed on a minor-league deal. Thomas struck out 16 times in 28 at-bats for the Twins and hit just .232/.281/.405 with a 109-to-22 strikeout-to-walk ratio in 109 games at Triple-A, so despite his big-league experience the 29-year-old outfielder now looks like little more than depth for Rochester.

• After appearing on "Gleeman and The Geek" two weeks ago Darren Wolfson of 1500ESPN.com did some digging and found that Rich Harden's minor-league contract with the Twins includes a July 31 opt-out clause. As far as opt-out clauses go that's a very late one, so if he doesn't look to be at full strength in spring training the Twins can stash Harden at Triple-A for a while and that makes what was already a worthwhile, low-risk flier look even better.

• Free agent Brett Myers was linked to the Twins by various sources throughout December, but ended up signing a one-year, $7 million deal with the Indians that includes an $8 million team option for 2014. And according to Wolfson the Twins never even made him an offer, which has become a familiar story this offseason and makes Kevin Correia's two-year, $10 million deal all the more confusing.

• And speaking of the Indians, they're the latest mid-market team to secure a new local television deal that significantly surpasses the Twins' current contract with FOX Sports North.

Adam Rubin covers the Mets for ESPN New York and had an interesting little note related to the Twins, reporting that they would have taken Jefry Marte from the Mets with the No. 4 pick in the Rule 5 draft had Ryan Pressly of the Red Sox not been available. Marte is a 21-year-old third baseman who hit just .251/.322/.366 at Double-A last season and was not selected by another team, with the Mets later trading him to the A's for Collin Cowgill.

Billy Bullock, the 2009 second-round pick traded to the Braves for the ability to stash Scott Diamond at Triple-A as a Rule 5 pick, was suspended 50 games for a "drug of abuse." He still throws hard with lots of strikeouts, but Bullock's control is awful and he's no longer a prospect at age 24. I hated that trade at the time and it's worked out very well for the Twins, although I still think they should have just kept Diamond as a long reliever and kept Bullock.

• On a related note, Diamond underwent minor elbow surgery to remove a bone chip and should be ready for spring training, but he won't pitch for Canada in the World Baseball Classic.

• In looking over Mike Pelfrey's career it struck me how amazing his draft class ended up being. Pelfrey was the No. 9 pick out of Wichita State and among the players selected ahead of him were Justin Upton, Alex Gordon, Ryan Braun, Troy Tulowitzki, and Ryan Zimmerman. But wait, there's more. Other top-30 picks included Andrew McCutchen, Jay Bruce, Cameron Maybin, Jacoby Ellsbury, Colby Rasmus, and Matt Garza, who the Twins took No. 25. That's crazy.

Jeff Clement was the No. 3 pick in that same draft--between Gordon and Zimmerman--and after hitting just .218/.277/.371 in 152 games for the Mariners and Pirates he'll likely spend this season at Triple-A for the Twins.

• After spending nearly all of last season in the Twins' bullpen despite adding to his lengthy track record of mediocrity with a 5.71 ERA and 26-to-22 strikeout-to-walk ratio in 52 innings Jeff Gray was dropped from the 40-man roster in late August. He went unclaimed on waivers, became a free agent, and agreed to a minor-league deal with the White Sox.

Kiley McDaniel, who formerly worked for several MLB teams, recently watched Miguel Sano and Byron Buxton play instructional league games and wrote very detailed, interesting scouting reports for Fan Graphs.

Francisco Liriano's two-year, $12.75 million deal with the Pirates is in jeopardy because of an offseason injury to his non-throwing arm.

• An oral history of Nick Punto sliding into first base is the best thing you'll read today.

• Podcast listeners who enjoy when we're interrupted by a drunk person will absolutely love this week's episode, and there's also some good Twins talk about how the roster is shaping up.

Real, fluke, or something in between: How good is Scott Diamond?

I liked the Twins' decision to pluck Scott Diamond from the Braves' farm system in the Rule 5 draft, writing at the time that "he's had success at every level" and "may be able to find success in the big leagues without missing a ton of bats" because he "has done a tremendous job inducing ground balls and limiting homers" in the minors. That was December of 2010 and later that offseason I ranked Diamond as the 36th-best prospect in the Twins' farm system.

I hated the Twins' decision to trade Billy Bullock to the Braves for Diamond to circumvent the stipulation that Rule 5 picks must remain in the majors all season or be offered back to their old team. It seemed silly to give up Bullock, a hard-throwing reliever drafted in the second round and given a $533,000 bonus just a year earlier, when the Twins already had Diamond and could have retained him simply by keeping him on the roster as a long reliever at age 24.

Diamond ended up spending nearly the entire second half of last year in the majors anyway, meaning the Twins basically traded Bullock for the ability to keep him in the minors for an extra three months. And in those three months Diamond had a 5.56 ERA at Triple-A, so it wasn't surprising when the left-hander struggled in his first taste of the big leagues with a 5.08 ERA and ugly 19-to-17 strikeout-to-walk ratio in 39 innings while allowing opponents to hit .317.

Bullock had issues of his own following the trade with a 4.44 ERA and 34 walks in 51 innings at Double-A, but he still threw in the mid-90s and still racked up 11.7 strikeouts per nine innings while holding opponents to a .199 batting average. Bullock continued to look like a potential late-inning reliever, Diamond continued to look like a potential back-of-the-rotation starter, and the Twins' thought process behind the trade continued to make little sense to me.

Despite making seven starts for the Twins down the stretch last season Diamond was never in the mix for an Opening Day roster spot this season, getting sent back to Triple-A as part of the first round of spring training cuts. He fared well in Rochester with a 2.60 ERA in six starts, but also allowed opponents to hit .270 and managed an unimpressive 26 strikeouts in 35 innings as a 25-year-old spending his third consecutive season at Triple-A.

When injuries and ineffectiveness wrecked the Twins' rotation for a second straight year they again turned to Diamond, calling him up on May 5. In returning to the majors Diamond brought with him a 4.50 ERA in 39 total Triple-A starts, which along with his modest 6.3 strikeouts per nine innings there and the equally modest fastball velocity he showed in debuting last season seemingly provided little reason for optimism.

And so naturally six weeks later Diamond has a 1.61 ERA through seven starts.

You can call it fluky or lucky or unsustainable or maybe even none of the above, but obviously Diamond isn't going to maintain a sub-2.00 ERA for very long. However, in watching Diamond's seven starts this season compared to his seven starts last season it's just as obvious that he looks like a much different pitcher. Looks can be deceiving, of course, but a deeper inspection of his numbers also shows significant improvement along with some good fortune:

YEAR     PA     SO%    BB%    HR%     GB%     LD%     BIP     LOB
2011    181    10.5    9.3    1.7    46.2    21.0    .338    67.4
2012    183    15.3    2.2    2.2    61.7    20.8    .308    82.6

Diamond faced 181 batters last year and has faced 183 batters this year, so while small the sample size is equal. He's gone from as many walks (17) as strikeouts (19) to a 28-to-4 ratio, increasing his strikeouts by 46 percent and decreasing his walks by 76 percent. He's allowed the same number of line drives and actually given up more homers, but Diamond's ground-ball rate went from neutral at 46 percent to among the league leaders at 62 percent.

He's also seen his luck even out a bit, as his batting average on balls in play went from .338 to a more typical .308 and his percentage of runners stranded on base went from slightly worse than average at 67 percent to substantially better than average at 83 percent. In his second go-around as a major leaguer Diamond's pitching and luck have both improved dramatically, although what he's thrown and how he's thrown it haven't changed all that much:

YEAR     PA     FB%     MPH     CB%     MPH     CH%     MPH
2011    181    58.4    88.9    27.7    79.9    14.0    83.0
2012    183    63.2    89.6    27.8    81.2     8.9    83.9

Compared to last year Diamond has cut down on his changeup in order to throw eight percent more fastballs while utilizing his curveball the same amount. He's added around one mile per hour to each of his three pitches, but Diamond's average fastball still clocks in at just 89.6 mph to rank 131st out of the 168 pitchers with 30 or more innings this season. His repertoire has been pretty similar, with a few tweaks, and the per-pitch results are also similar within that:

YEAR     PA    STR%    ZON%    1PS%    SWG%    MIS%
2011    181    63.3    49.4    59.5    45.9    15.9
2012    183    65.6    51.8    61.1    44.3    13.0

Diamond has gotten slightly more strikes, thrown slightly more pitches in the strike zone, and jumped ahead of batters with first-pitch strikes slightly more often, but all three of those rates are within a couple percentage points of last season and he's actually induced slightly fewer swings and slightly fewer misses than in 2011. Add it all up and Diamond's results are vastly improved, but his raw stuff and general approach haven't changed a ton.

That could mean he's simply learned to make better pitches, which would obviously be a good thing, but it could also mean he's been fortunate that pitches thrown at roughly the same velocity and roughly the same frequency have created far better results. There's no doubt that Diamond has looked and pitched better, but exactly how much better and the sustainability of his improvement is an interesting question that will require more than 14 starts to answer.

For now I'm cautiously optimistic that Diamond can be a solid third or fourth starter, although admittedly fifth starter was more likely based on his track record prior to rejoining the Twins last month. He throws strikes and keeps the ball on the ground, which is a great foundation for success, and if Diamond can maintain any kind of decent strikeout rate he could be part of the Twins' rotation for a long time. Or at least long enough to make everyone forget Bullock.

Nevermind, I’ll find someone like you

Catching up with old friends in new places ...

Matt Guerrier signed a three-year, $12 million deal with the Dodgers and got off to a great start in Los Angeles with 11 straight scoreless innings before coughing up five runs Saturday. Guerrier has filled largely the same role with the Dodgers that he did with the Twins, working the seventh and eighth innings setting up closer Jonathan Broxton while recording more than three outs in five of his first 10 appearances.

Brian Fuentes has been filling in for the injured Andrew Bailey as the A's closer, converting six of seven save chances with a 4.09 ERA and 10-to-5 strikeout-to-walk ratio in 11 innings. He was unable to find a full-time closing opportunity as a free agent and settled for a two-year, $10.5 million deal at age 35. Bailey is due back early next month, at which point Fuentes will slide into a setup role alongside former Twin and original AG.com favorite, Grant Balfour.

Jon Rauch also stumbled into a brief stint filling in as Toronto's closer with Frank Francisco sidelined to begin the season. Just as he did for the Twins last year Rauch did a perfectly solid job in the role, converting all three save chances before Francico returned 18 games in, and he has a 2.25 ERA and 6-to-4 strikeout-to-walk ratio in nine innings overall. Dating back to last year Rauch has converted 24-of-28 saves with a 2.98 ERA and 52/18 K/BB ratio in 66 innings.

• Obviously the three-year, $13 million contract helped, but Jesse Crain also talked about the opportunity to be in the mix for saves as one of the reasons for signing with the White Sox. Chicago's bullpen has been a mess, with closer Matt Thornton blowing four saves already and manager Ozzie Guillen trying all kinds of different combinations late, but Crain has yet to get a crack at closing duties despite a 1.93 ERA and 11-to-2 strikeout-to-walk ratio in nine innings.

Orlando Hudson got off to strong start in San Diego while oddly batting third in the Padres' lineup, but a recent slump has knocked his overall line down to .229/.349/.271 in 21 games. Of course, even that .620 OPS is still much higher than the Twins have gotten from Alexi Casilla (.485), Matt Tolbert (.469), Luke Hughes (.448), and Tsuyoshi Nishioka (.519) in the middle infield and Hudson is playing half his games in the majors' most pitcher-friendly ballpark.

• I didn't like the Twins' decision to trade J.J. Hardy after he was above par offensively among shortstops and outstanding defensively in the 101 games he was healthy enough to be in the lineup, but they have to be smiling after he lasted just six games with the Orioles before being placed on the disabled list. Hardy is out until mid-May with a strained oblique and one of the two minor-league relievers the Twins got for him, Jim Hoey, has been thrust into a setup role.

Brendan Harris was also traded to Baltimore in the Hardy swap or more accurately dumping $1.25 million of his $1.75 million salary on the Orioles was part of the Twins' side of the deal. No one will ever be able to explain why the Twins handed Harris a two-year, $3.2 million deal last January, but after spending most of last season at Triple-A he failed to make the Orioles out of spring training and is once again struggling in the International League.

Wilson Ramos has overtaken Ivan Rodriguez as Washington's starting catcher and all of a sudden articles have popped up explaining how the Twins don't regret trading a 22-year-old top catching prospect for the right to pay $10 million for one-and-a-half years of Matt Capps. I'm sure the timing is purely coincidental. Ramos is hitting .351 with surprisingly decent plate discipline early on, giving him a .302/.347/.414 career line through 34 games.

Dealt for Single-A reliever Paul Bargas in December after the Twins settled on Drew Butera as their preferred backup catcher, Jose Morales is now backing up Chris Iannetta in Colorado and playing sparingly in the early going. He owns a career line of .295/.374/.358 in 81 games, but the Twins never trusted his glove. Bargas unfortunately has been hospitalized due to a neurological condition, with general manager Bill Smith describing him as "very sick."

Nick Punto's one-year, $750,000 contract with St. Louis got off to a rough start when he underwent hernia surgery within days of reporting to spring training, but he's healthy now and already starting regularly in place of injured second baseman Skip Schumaker. I thought the Twins should have re-signed Punto as long as the money was no more than $1 million and the projected role was minor. For all his faults, he'd be their best middle infielder right now.

Pat Neshek not only won a spot in the Padres' bullpen out of spring training after being lost on waivers for nothing by the Twins, he threw eight innings with a 2.25 ERA and .222 batting average against. However, while I'm happy to see Neshek doing well and didn't understand cutting him loose, his 7-to-5 strikeout-to-walk ratio is anything but impressive, his average fastball has clocked in at just 85.6 miles per hour, and now he's been optioned to Triple-A.

• Traded to the Braves for Rule 5 pick Scott Diamond last month in one of the most confusing Twins moves in a long time, Billy Bullock has struggled at Double-A with a 12.15 ERA through 6.2 innings. He thrived at Double-A in the second half of last season, but his shaky control has been a big problem with six walks. Diamond, meanwhile, has a 3.48 ERA and 13-to-8 strikeout-to-walk ratio in three starts at Rochester.

Rob Delaney was lost on waivers to Tampa Bay in late January when they Twins dropped him from the 40-man roster to make room for Dusty Hughes. Delaney failed to make the Rays out of spring training, but has a 2.45 ERA and 14-to-3 strikeout-to-walk ratio in 11 innings at Triple-A and will likely get a chance in Tampa Bay at some point this season. Hughes has been a mess so far, living up to his mediocre track record by allowing seven runs in seven innings.

Ron Mahay left the Twins as a free agent, signed a minor-league deal with the Dodgers only to be released in the final week of spring training, and has latched on with the Diamondbacks at Triple-A, continuing a career-long pattern of having to prove himself anew seemingly every season despite consistently solid numbers. He might finally just be out of gas at age 40, but Mahay has a career ERA of 3.83 that includes a 3.49 mark in the previous five seasons.

Dennys Reyes beat out Hideki Okajima for the left-handed specialist role in the Red Sox's bullpen coming out of spring training, turning a minor-league deal into $900,000 in guaranteed money, and then got demoted to Triple-A one week into the season after four shaky outings. Reyes cleared waivers and accepted an assignment to Pawtucket, but the $900,000 salary is locked in whether "Big Sweat" gets called back up to Boston or not.

Yohan Pino, a right-hander the Twins swapped to the Indians for Carl Pavano in mid-2009, was traded to the Blue Jays last week for cash considerations. Pino was a mid-level prospect when the Twins dealt him, posting standout numbers in the minors despite mediocre raw stuff, and now he's organizational filler at age 28. Pavano was an impending free agent back then, but went on to re-sign with the Twins twice and has a 4.09 ERA in 326 innings since the trade.

Twins trade Billy Bullock to keep Rule 5 pick Scott Diamond

Some trades seem like good moves, some trades seem like bad moves, and some trades seem like bad moves and don't make much sense. Yesterday's trade with the Braves to retain Rule 5 pick Scott Diamond unfortunately qualifies as the latter, as the Twins swapped a high-upside, hard-throwing reliever prospect in Billy Bullock for a low-90s throwing left-hander who wasn't even protected from the Rule 5 draft and projects as no more than a mid-rotation starter.

In the wake of the deal there are reports about the Twins wanting Diamond so much that they nearly traded up in the Rule 5 draft to make sure they got him and reports about how they've since grown to like him even more this spring. And that's fine. I like Diamond too and when the Twins plucked him from the Braves in the Rule 5 draft four months ago I wrote about him being a nice low-cost pickup for the total investment of just $50,000 and a spot on the MLB roster.

However, the Twins apparently didn't love Diamond enough to give him one the seven spots in their bullpen as a long reliever or mop-up man and because of that were forced to either offer him back to the Braves or work out a separate deal to keep him in the minors outside of the Rule 5 system. They chose to work something out with Atlanta, which is perfectly reasonable in theory, except "something" inexplicably turned out to be a far better prospect than Diamond.

Bullock was the Twins' second-round pick in 2009 and the 6-foot-6, 230-pounder signed for a $533,000 bonus, posting a 3.18 ERA with 150 strikeouts in 108 innings through two seasons while advancing all the way to Double-A as a 22-year-old. He has control problems, but that comes with the mid-90s fastball that made the former University of Florida closer perhaps the hardest-thrower in a farm system perpetually loaded with potential mid-rotation starters.

All offseason the Twins talked of wanting to acquire more big, hard-throwing strikeout pitchers with overpowering raw stuff, yet they traded arguably the best example of that in their entire organization for a mid-rotation starter they already controlled and could have kept for nothing by simply giving him a low-leverage job in a bullpen housing seven relievers. I'm dumbfounded by the move purely on a talent level, but even more so because of the Rule 5 aspect.

Atlanta didn't even deem Diamond worthy of a 40-man roster spot to protect him from the Rule 5 draft in December and he lasted all the way to the Twins with the 27th selection, later going unclaimed on waivers this week, yet the Braves somehow just turned him into a power arm two years removed from being a second rounder. And all because the Twins weren't willing to trust Diamond with a long relief job that would've allowed them to keep him for nothing.

I'm admittedly a bigger Bullock fan than most, viewing him as a potential future closer and the epitome of the type of high-upside arm the Twins should be trying to add while ranking him as the team's No. 10 prospect (whereas Diamond placed No. 36). But clearly I'm not alone, as the Twins liked Bullock enough to spend a second-round pick and $533,000 on him 20 months ago and Baseball America ranked him as the No. 15 prospect in the system, with Diamond at No. 29.

You'll be hard-pressed to find anyone who values Diamond higher than Bullock. Except for the Twins, apparently. Yet if they love Diamond that much the Twins could have just stuck him in a low-leverage bullpen role like they did with Johan Santana in 2000. And if they don't love him enough to let Diamond fill one of the seven bullpen jobs at age 24 so they could retain him for nothing, then why trade a high-upside, consensus top-20 prospect for him? I just don't get it.

Top 40 Twins Prospects of 2011: 10, 9, 8, 7, 6

Also in this series: 1-5, 11-15, 16-20, 21-25, 26-30, 31-35, 36-40.

10. Billy Bullock | Reliever | DOB: 2/88 | Throws: Right | Draft: 2009-2

Rarely have the Twins averted from drafting pitchers with superior command and control than raw stuff, but 2009 second rounder Billy Bullock was an obvious exception and so far at least the former University of Florida closer has lived up to his pre-draft billing as one of the highest-upside arms in the class. Bullock has a legitimate mid-90s fastball and even without much of an off-speed repertoire he's racked up an incredible 150 strikeouts in 108 pro innings.

All those missed bats have also come with 4.7 walks per nine innings, so his control will have to improve when Bullocks starts to face more advanced competition not so easily overpowered with pure velocity. On the other hand he had no trouble dominating Double-A hitters following a midseason promotion last year, striking out 60 batters in 37 innings and posting a 3.44 ERA despite 5.9 walks per nine frames. He doesn't know where it's going but it's getting there fast.

Bullock has been used as a closer in the minors, accumulating 38 saves and finishing 79 games in 91 total appearances, and with a bit more refinement he certainly projects as a ninth-inning possibility in Minnesota some day. He's been promoted aggressively by the Twins despite the awful control, reaching low Single-A shortly after signing for $533,000 and finishing his first full season in Double-A at age 22, so with a few more strikes Bullock could arrive in a hurry.

9. Adrian Salcedo | Starter | DOB: 4/91 | Throws: Right | Sign: Dominican

Adrian Salcedo signed with the Twins out of the Dominican Republic as a 16-year-old in 2007 and made his pro debut in 2008 by dominating the Dominican summer league with a 1.65 ERA, .198 opponents' batting average, and 50-to-8 strikeout-to-walk ratio in 65 innings. He moved up to the rookie-level Gulf Coast League in 2009 and the skinny, 6-foot-4 right-hander posted more video game-like numbers with a 1.46 ERA and 58/3 K/BB ratio in 62 innings.

Like many very young prospects Salcedo began last year in extended spring training and was slated for rookie-level Elizabethton once the short-season Appalachian League started up, but when injuries depleted Fort Myers' pitching staff the Twins surprisingly sent him all the way up to high Single-A. Not surprisingly for a 19-year-old facing Florida State League hitters 3-4 years his senior, Salcedo struggled with a 6.26 ERA in six starts before heading to Elizabethton.

Obviously the rough stretch at Fort Myers isn't a positive thing, but it's tough to blame Salcedo much for a poor 2010 performance at a level he may not have reached until 2012 under normal circumstances. And once he was back to facing guys his own age Salcedo resumed dominating with a 3.27 ERA and 65/10 K/BB ratio in 66 innings to finish the year on a high note. He'll likely begin this season at low Single-A and perhaps return to Fort Myers in the second half.

Liam Hendriks signed with the Twins out of Australia as an 18-year-old in 2007 and fared well at rookie-ball, but then missed all of 2008 and half of 2009 following knee and back surgeries. Hendriks didn't miss a beat when he finally returned to the mound, tossing 84 innings with a 3.55 ERA and 75-to-16 strikeout-to-walk ratio between rookie-ball and low Single-A, and then turned in by far the most impressive performance by any pitcher in the Twins' system last year.

Hendriks began the season back at low Single-A, where he had a 1.32 ERA and 39/4 K/BB ratio in six starts to earn a quick promotion to high Single-A. He missed some time at Fort Myers due to an appendectomy that also kept him from pitching in the Futures Game, but the 6-foot-1 right-hander still dominated Florida State League hitters with a 1.93 ERA and 66/8 K/BB ratio in 75 innings despite being one of the youngest starters in the league at age 21.

His overall numbers between the two levels were ridiculous, with a 1.74 ERA, .199 opponents' batting average, 105/12 K/BB ratio, and just two homers allowed in 109 innings. His raw stuff can't match that dominance, but Hendriks has excellent command of a five-pitch repertoire that includes a low-90s fastball. Performance-wise he's been nearly flawless, but with a grand total of 236 innings in four pro seasons staying healthy is key as he moves beyond the low minors.

7. Ben Revere | Center Field | DOB: 5/88 | Bats: Left | Draft: 2007-1

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO

Ben Revere was initially thought to be done for the year when a pitch to the face fractured his right orbital bone in early August, but instead he rejoined the Double-A lineup and then made his unexpected MLB debut in September when the Twins put him on the 40-man roster after Ron Gardenhire requested some speed. Revere even drew a half-dozen starts in place of an injured Denard Span, but the 2007 first-round pick figures to spend most of 2011 at Triple-A.

Flirting with a .400 batting average at low Single-A in 2008 made it easy to overlook Revere's flaws, but his non-existent power and sub par plate discipline certainly stood out more during the past two seasons as he hit "only" .311 and .305. He managed just three homers, 34 total extra-base hits, and 72 walks in 215 games and 923 plate appearances during that time, and then hit .295 with a measly .330 slugging percentage in 28 games in the Arizona Fall League.

Great speed, few strikeouts, and a line-drive swing make Revere capable of hitting .300 in the majors, but even if he does a glaring lack of secondary skills would leave him with limited value offensively. An empty batting average works when joined by elite defense and base-stealing, but there are questions about Revere thriving in center field and he's yet to turn great speed into great success rates on the bases. Right now he looks like a poor man's Juan Pierre.

6. Joe Benson | Center Field | DOB: 3/88 | Bats: Right | Draft: 2006-2

YEAR     LV      PA      AVG      OBP      SLG     HR    XBH     BB     SO
2008     A-     290     .248     .326     .382      4     23     24     73
2009     A+     327     .285     .414     .403      5     18     46     74
2010     A+      96     .294     .375     .588      4     16      8     21
         AA     423     .251     .336     .527     23     50     39    115

Joe Benson got off to a brutal start at Double-A last year, hitting .169 in April, but recovered to hit .283/.411/.609 during the first two weeks of May when the Twins demoted him to Single-A anyway. It was an odd move, as the Twins cited his strikeout total and poor batting average even though he'd been on fire for two weeks and led New Britain in OPS, but Benson took the demotion in stride and hit .294/.375/.588 with 16 extra-base hits in 21 games at Fort Myers.

That earned Benson a mid-June promotion back to Double-A, where he continued to crush the ball and finished with an .862 OPS that led the team by 127 points and was 18 percent above the Eastern League average. Combined between the two levels he hit .259/.343/.538 with 27 homers, 19 steals, and 66 total extra-base hits in 123 games. Benson had the highest OPS in the Twins' system by 52 points and topped the next-best Isolated Power by 37 percent.

Benson's power really stands out in a system where no other hitter had 20 homers or slugged .450, but controlling the strike zone remains a big issue. He struck out 136 times in 123 games and hit .251, both of which match his career marks. As a great athlete with plus speed and the range for center field he brings much more to the table than most low-average, high-strikeout guys, but before projecting him as a star Benson still has a lot to prove in his age-23 season.
