Robinson Cano (NYY):  A graceful hitter and smooth second baseman who has power and a keen batting eye…  Edged Hill in the closest race for top billing at his position.  Something tells me that, offensively, Cano can still be better.  Just a shade below Teixeira in total production, but a touch more valuable overall.  (120.2 Runs Created, 16.4 Runs Saved = 136.61 Total Run Production)

Aaron Hill (TOR):  Came back with a vengence – had his career year as a comeback season.  I would never have guessed 36 homers and I don’t know that it will happen again.  To be fair, his 2007 season left room for a potential breakout like this – if you remember it: 47 doubles and 17 homers in 74 fewer at bats than he had in 2009.  Still – a remarkable season and I’ll root for him to repeat.  (117.7 Runs Created, 18.8 Runs Saved = 136.46 Total Run Production)

Ben Zobrist (TB):  Speaking of breakout seasons – took over when Akinori Iwamura went down and played a solid second base while hitting like an outfielder.  Would you have guessed this when he hit 5 homers in 388 at bats in A Ball?  Or in 2006 when he hit 5 homers in 567 at bats at three different levels?  He started showing flashes of power in 2007 at Durham, cranked it up as a reserve in 2008, and launched his career with power, patience at the plate, and an amazing season.  Like Hill, however, I don’t think he’s going to repeat it…  Turns 29 in May.  (114.8 Runs Created, 9.8 Runs Saved = 124.63 Total Run Production)

Ian Kinsler (TEX):  30 – 30 member (31 of each, actually) and someone ANY team would be proud to have.  He and Andrus seal up the middle defensively like nobody’s business.  First season of 140+ games, in his three previous seasons he had missed a month somewhere…  He’s the new Joe Gordon – if anyone is old enough to remember the original.  (92.7 Runs Created, 14.8 Runs Saved = 107.46 Total Run Production

Placido Polanco (DET):  Doesn’t have the power of the top four guys, but gets his share of hits and still makes all the plays defensively.  To hear it at the end of the year, though, people were saying Polanco had lost a step.  By my calculations, he was the best defensive second baseman in the AL – and it was the best season of the last four that I have tracked.  I don’t think he’ll have the same impact in Philadelphia – he’s not quite the same hitter and he’s moving to a less familiar position.  Detroit will be hard pressed to get similar production in 2010 at this position.  (82.4 Runs Created, 23.4 Runs Saved = 106.15 Total Run Production

By the way, the guy who might have the top shot at second base is Scott Sizemore.  Sizemore hit .308 last year in AA and AAA with 17 homers, 21 stolen bases, and has a .383 OBP in his minor league career.  He’s been a top ten prospect each of the last three seasons after being drafted in the fifth round out of Virginia Commonwealth in 2006.  We’ll see if he’s got the goods defensively, but the Tigers took a reasonable gamble in letting Polanco go to give Sizemore a shot.

Dustin Pedroia (BOS):  Still a solid performer offensively, but took a step back with the glove.  I don’t think anyone was serious about moving him to short – Pedroia doesn’t look like he has that kind of throwing arm.  He’s such a high energy guy, I worry about him running out of gas earlier than other guys because he’s going to run himself into the ground; but you never know.  (105.2 Runs Created, -14.50 Runs Saved = 90.68 Total Run Production)

Jose Lopez (SEA):  Good power, but little patience at the plate.  And, he’s not as good a fielder as the top guys.  I have him below average in three of the last four years and I don’t think he’s going to get better.  I don’t see Lopez getting replaced anytime soon – but his window of productivity might be smaller than other guys and the Mariners talk about moving him to first base.  (89.9 Runs Created, -10.7 Runs Saved = 79.17 Total Run Production)

Brian Roberts (BAL):  Fantastic leadoff hitter – a bit of power, gets on base, steals bases at a decent rate.  Offensively, he’s one of the five best second basemen.  And then you have his glove, which took a step back last season and affected his rating.  Like Paul Molitor, maybe he should become a first baseman/DH in a couple of years…  (106.6 Runs Created, -31.2 Runs Saved = 75.49 Total Run Production)

Adam Kennedy (OAK):  Played shorstop and second but not as the regular; slightly below average at both positions defensively but wasn’t a total loss offensively.  Mark Ellis had the job most of last year (see below), but if you were looking for options Kennedy might be worth a look.  Uh – Minnesota, can you hear me?  (80.7 Runs Created, -10.37 Runs Saved = 70.36 Total Run Production)

Alberto Callaspo (KC):  Got a full season and hit enough but was a disaster in the field.  In his defense, it was his first full season, but he had 365 innings there in 2008 and they weren’t necessarily pretty.  Still – mid range power and a .300 batting average is a good starting point.  Turns 27 this year, so he COULD break out and push 15 to 20 homers and have a Dustin Pedroia type season.  (89.8 Runs Created, -22.97 Runs Saved = 66.82 Total Run Production)

Luis Valbuena (CLE):  I think he’ll be okay if he gets a full shot at the job.  Some power, could use patience and more contact, but plays second base well enough.  Acquired in the deal that sent Franklin Gutierrez to Seattle, he’s just 24 and on his way.  If you are in a keeper league, scoop him up.  (50.2 Runs Created, 14.9 Runs Saved = 65.11 Total Run Production)

Howie Kendrick (LAA):  Better contact hitter than Valbuena, but not the fielder Luis is…  I did a study some time ago where long time second sackers were out of gas if they couldn’t generate at least 60 runs of offense – no matter how good a fielder.  In Kendrick’s case – he needs to step up for a full season and put his career in gear.  Howie has the tools to do it.  (56.9 Runs Created, -6.0 Runs Saved = 50.93 Total Run Production)

Mark Ellis (OAK):  On the downside of his career, but able to help out because he still has some power, patience and range.  His body may not cooperate much longer, but as long as Ellis can get to the playing field, he’ll contribute.  (49.2 Runs Created, 1 Run Saved = 50.17 Total Run Production)

Chris Getz (CWS):  Now in Kansas City because they can’t get enough utility middle infielders…  Getz doesn’t hit for a high average, and he while he has some patience, doesn’t have a really high on base percentage either.  He can field a little bit.  That makes him Tim Foli.  The White Sox have decided to move Gordon Beckham to second – which may not help the defense but will help put a few more runs on the board.  (45.5 Runs Created, 3.8 Runs Saved = 49.25 Total Run Production)

Nick Punto (MIN): Shared the position with Alexi Casilla and Matt Tolbert, and neither of them was really good enough.  None of the three can hit – Tolbert and Casilla can play the field, and Punto is the new Mick Kelleher or Steve Dillard.  We’ll see him coaching in a few years.  As of 2/4, the Twins still haven’t resolved this hole but if Orlando Cabrera or Orlando Hudson are still available, get him.  The closest thing to a middle infield prospect might be Brian Dinkelman, a AA infielder who looks like Jeff Treadway with a bit better glove but is still a year away and already 26 years old…

Notes: Like the first basemen, the median second baseman is producing about 75 runs, which means that Cano and Hill were worth about six extra wins each to his respective team.
