• Not only has Jim Thome switching from the White Sox to the Twins had a massive impact on the AL Central race, Baseball-Reference.com's blog points out that he's having one of the best seasons ever by a 39-year-old (he actually turned 40 over the weekend, but this is his age-39 season). Here are the all-time leaders in adjusted OPS+ at age 39:

AGE 39              YEAR      PA     OPS+
Barry Bonds         2004     617     263
Ted Williams        1958     517     179
Hank Aaron          1973     465     177
JIM THOME           2010     279     161
Babe Ruth           1934     471     161

Thome has fewer plate appearances than everyone else on that list, but he's on pace to finish with approximately 350 and any time you can make a top-five list alongside Barry Bonds, Ted Williams, Hank Aaron, and Babe Ruth you're doing something really right. Paul Molitor is the only other player in Twins history to post an OPS+ above 100 at age 39, hitting .341/.390/.468 in 728 plate appearances for a 116 OPS+ in 1996.

And if you're already thinking about the Twins possibly re-signing Thome for next season, here are the all-time leaders in OPS+ at age 40:

AGE 40              YEAR      PA     OPS+
Willie Mays         1971     537     158
Carlton Fisk        1988     298     155
Edgar Martinez      2003     603     141
Moises Alou         2007     360     137
Dave Winfield       1992     670     137

That's a much different and less impressive list in terms of both names and numbers, which is a good reminder of how tough it is to dominate at age 40. In fact, based on OPS+ no hitter in the history of baseball has ever been as productive as a 40-year-old as Thome has been as a 39-year-old, which is something to keep in mind when it comes to 2011 expectations for the future Hall of Famer. Of course, I loved the signing at the time and would love to see him back.

• I made a rare weekend post analyzing the Brian Fuentes trade, so read that if you missed it Friday night. I wondered how Ron Gardenhire will use Fuentes down the stretch, but so far so good. Gardenhire smartly pulled Nick Blackburn after 8.2 scoreless innings Saturday when he walked speedster Chone Figgins as the tying run in a 1-0 game, bringing in Fuentes to get the 27th out with left-handed slugger Russell Branyan at the plate.

Fuentes dispatched Branyan with ease and in doing so hinted that perhaps Matt Capps won't always get the call in the ninth inning when dangerous left-handed bats are due up. Fans and media instinctively balked at the notion of "closer by committee" when Joe Nathan went down, but if Fuentes isn't needed early in a game bringing him in for tough ninth-inning lefties makes sense. I'm skeptical after the Twins focused on Capps' closing experience to explain that deal.

October 15 is the deadline for the Angels to pick the player to be named later they receive for Fuentes, but all indications are that they're choosing from a list of fairly marginal prospects and some reports even suggest "cash" could be substituted for the player. I already liked the deal when I thought the PTBNL could end up being a mid-level prospect, so a low-level prospect or cash would make it even more of a no-brainer.

There seems to be a lot of confusion about Fuentes' contract status, so let's try to clear it up. He has a $9 million option for 2011 that vests with 55 games finished, but that's a moot point with just 34 so far. He'll be a free agent and get Type A or B status, so in theory the Twins can receive compensation when he leaves. However, that first requires offering Fuentes arbitration and since he could guarantee himself $10 million by simply accepting the Twins won't do it.

Fuentes is a six-week rental, and a good one.

• Luke French is the 47th left-handed starting pitcher the Twins have faced in 131 games this year, which means they've been matched up against a lefty 36 percent of the time compared to the league average of 29 percent. Jason Kubel started at designated hitter versus French and has started 34 of the 47 games against lefties despite hitting just .210/.306/.341 off them this season and .232/.312/.352 off them for his career.

Much like Jacque Jones before him, Kubel's career-long ineptitude versus lefties makes him an obvious platoon player who Gardenhire simply refuses to platoon. Even worse, Kubel was in the cleanup spot yesterday, which is the third time he's batted cleanup against a lefty. In fact, he's yet to hit in the bottom third of the lineup versus a lefty this season, batting nine times in the fifth spot and 22 times in the sixth spot along with the three cleanup starts.

And while he was at DH yesterday, Kubel has been in right field for 17 of the 34 starts versus lefties, which means in 13 percent of their total games the Twins have chosen to combine poor defense in right field with a .650 OPS from the middle of the lineup. Not having Justin Morneau since early July has made it impossible for Gardenhire to use his preferred lineups, but in half of Kubel's starts against lefties Morneau was also in the lineup. Platoon him, please.

• Every time the Twins make a change to the bullpen--and there's been no shortage of them recently--I get comments, e-mails, and tweets asking about Pat Neshek. Fans (and bloggers) love Neshek and want to see him succeed after Tommy John surgery, but because the Twins weren't pleased with how he handled his post-surgery finger injury he's become sort of the forgotten man at Triple-A (and is choosing to fly under the radar by not speaking to reporters).

He's pitched well since being sent to Triple-A in early June following a DL stint, going 4-1 with a 3.47 ERA, .263 opponents' batting average, and 24 strikeouts versus six non-intentional walks in 36.1 innings, but certainly hasn't been dominant or close to Rochester's best reliever. He's apparently no sure thing to get a September call-up and based on performance alone--rather than his history and presence on the 40-man roster--no one would be clamoring for Neshek.

• Wilson Ramos made his Nationals debut last week, but was only called up for a couple days with Wil Nieves away from the team. Ramos went hitless in his only game before being sent back to the minors, making him 1-for-22 since starting his career with seven hits in his first two games. He has hit .319/.347/.514 in 18 games at Triple-A since being swapped for Capps last month and will be back in Washington when rosters expand later this week.

• After basically taking two months off before signing for $1.3 million a week or so before the deadline, first-round pick Alex Wimmers has been assigned to high Single-A for his pro debut. He's pitched twice so far at Fort Myers, tossing 5.2 scoreless innings with an 8-to-3 strikeout-to-walk ratio and .105 opponents' batting average while on a strict pitch count. By assigning him directly to high Single-A the Twins have set him up to advance through the system quickly.

• Denard Span was caught trying to steal third base yesterday, so dating back to last season he now has 42 stolen bases while being thrown out or picked off 31 times. Yuck.
