Most Improved Hitters So Far, Per ZiPS
As the reader will know, we carry a tidy collection of projection systems here at the site — of which two now, Steamer and ZiPS, are updated daily with constantly changing rest-of-season and overall total projections. Together, the two systems provide important data for our new Standings tool. Another use is to see which players’ season performances to date have most altered their rest-of-season projections.
This week, in the Notes, we’re considering those hitters and pitchers whose projections have most improved. Yesterday, we looked at the most improved hitters according to Steamer — where “most improved” was defined as “greatest increase in wOBA projection.” Below are the most improved hitters, except now according to ZiPS.
Note: because the final preseason edition of ZiPS is released relatively early, there are a number of players originally projected with one team but now playing with, and being projected for, another. The change in teams also means a change in park effects, and therefore a change in raw wOBA. As such, I omitted from my search any player who might be subject to this effect. That stated, Mike Carp (97 wRC+ preseason, 110 wRC+ rest-of-season) and Vernon Wells (97 wRC+ preseason, 107 wRC+ rest-of-season) deserve recognition.
5. Evan Longoria, 3B, Tampa Bay
ZiPS (Pre): 538 PA, .263/.355/.486 (.289 BABIP), .358 wOBA, 132 wRC+
ZiPS (RoS): 431 PA, .276/.365/.508 (.306 BABIP), .373 wOBA, 140 wRC+
Notes: Speaking anecdotally, at least, ZiPS appears to be more aggressive than Steamer in terms of integrating recent performances into its rest-of-season projections. By way of example, the player (Josh Donaldson) occupying the fifth spot on the Steamer version of this list from yesterday has been assigned only a 10-point improvement in his rest-of-season wOBA projection and four-point improvement in wRC+. Longoria, meanwhile, has posted 15- and eight-point improvements, respectively.
