Jason Bay: 338 Plate Appearances, 0.6 WAR (Fangraphs)
Scott Hairston: 108 Plate Appearances, 0.8 WAR
I'm not going to pretend that Scott Hairston's level of production (swelled, obviously, by his game yesterday) is sustainable (if it were, and he played the whole season, he'd have the 3rd-highest WAR on the Mets, behind only Reyes and Beltran), but at this point playing Bay over him is folly. He clearly has far more raw power (.296 vs .095 ISO), and is simply a better player. I know this is beating a horse that has already been fashioned into glue, but if the Mets are going to continue to toy with the idea of contention, it simply doesn't make sense to keep giving Bay starts in left. I'm tired of getting false hope every time Bay flares a single to right-center that "this time" maybe he's got it. If the Mets are going to do things like using Izzy over Parnell as a closer - indicating that they're placing a priority on winning games this year - then it's about time Hairston got his shot.
