The Most Improved Positions of 2012
Teams don’t always have to make a major move in order to improve over the winter. Sometimes merely subtracting someone who played poorly can affect our expectations for a club. Occasionally, a series of seemingly minor moves can make a major cumulative impact. And at other times, there’s an obvious in-house fix for a roster’s flaws in the form of a player returning from an injury, being promoted from the minors, or switching to a position where he’ll be of more use. The Rays went from last place in 2007 to first place in 2008 without acquiring an outside player more accomplished than Troy Percival. Some off-season overhauls don’t start making headlines until the regular season is well under way.
Still, the moves that make us dream about how good a given team can be when players report to spring training tend to be the ones involving established talents. When we’ve already seen what a player can do, it’s easy to picture him doing it again in a different uniform. Naturally, the more a team struggled at the new player’s position last year, the more exciting the upgrade. But it’s easy to get carried away and overstate the improvement. Assessing the impact of a high-profile player addition requires more than a little imagination and mental arithmetic.
Using the rate statistics predicted by PECOTA, Baseball Prospectus’ proprietary projection system, and the human-generated playing-time estimates contained in our depth charts, we’ve come up with an estimate of what each team can expect from each position in 2012. By comparing those estimates to the production we know those teams got from the same positions last season, we can pinpoint the biggest positional improvements according to BP’s total value metric, Wins Above Replacement Player (WARP). The following seven positions improved by an estimated two wins or more this winter thanks to a trade or free-agent signing.
Angels, First Base (4.9 WARP improvement)
Albert Pujols is one such expensive exception. The Angels spent $240 million on the winter’s most coveted free agent, and PECOTA projects that they’ll get more than their money’s worth, at least in 2012. Before his final year in St. Louis, Pujols hadn’t been worth less than 7.8 WARP in a season since 2002, and despite his slow start and subsequent wrist fracture, he was still a six-win player last season. PECOTA expects him to approach the eight-win mark again in Anaheim. That means the Angels can expect to add about five wins at first base, not to mention another 1-2 trickle-down wins at DH.
Mariners, Designated Hitter (3.9 WARP improvement)
Michael Pineda may have been a high price to pay for someone who probably can’t play the field, but in former Yankees prospect Jesus Montero, the Mariners may have gotten themselves another Edgar for the foreseeable future. PECOTA isn’t expecting miracles from Montero in his first full season, but a .290 True Average (TAv) and 24 homers, plus some solid supplemental work from Mike Carp, would make for a substantial improvement over the losers of the past several seasons.
Brewers, Third Base (3.9 WARP improvement)
Aramis Ramirez isn’t quite the player that his bat makes him out to be, since his work outside the batter’s box leaves a lot to be desired. His fielding and baserunning cost the Cubs two wins last season, making him more of a 2-3 win player than the 4-5 win force he’d be if he were even average away from the plate. However, he still represents nearly a four-win improvement over what McGehee gave Milwaukee last season, which should make up most of the deficit Prince Fielder’s departure opened up on the other side of the diamond.
Angels, Catcher (3.1 WARP improvement)
Angels GM Jerry Dipoto emphasized the importance of on-base percentage shortly after taking over last October, and he backed up his words by trading for Chris Iannetta a month later. The former Rockies catcher has walked in 13.9 percent of his career plate appearances, a higher rate than any Angels regular managed last season. He hasn’t hit as well away from Coors Field, but he still has a career .268 TAv, which means he’s been an above-average hitter (and a well above-average offensive catcher), even after adjusting for his home park.
Marlins, Shortstop (2.4 WARP improvement)
Since Reyes’ arrival will push Ramirez to third base, where the Marlins made do with Greg Dobbs for most of last season, the team’s greatest gains may come at the hot corner. Assuming Hanley stays healthy and happy and his bat rebounds, Miami might be almost eight wins better on the left side of the infield.
Padres, Left Field (2.4 WARP improvement)
Rockies, Second Base (2.3 WARP improvement)
The Rockies allowed Ellis to leave via free agency and traded low-upside arm Clayton Mortensen to the Red Sox for Marco Scutaro. From 2008-2011, only four shortstops contributed more to their teams than Scutaro’s 14.0 WARP. His bat won’t be quite as valuable an asset at second base, but his glove should be even better-equipped to handle the demands of his new position. It’s rare to see the Sox unload a quality player in search of salary relief, but in this instance, the Rockies benefited from Boston’s desire to stick to a budget.
