a productive hitter in 2013, either with the Mets or with another team, but the odds are very slim. Like Castillo and Perez were heading into 2011, Bay is a sunk cost. If the Mets keep him through the entire season, they will be a worse team as a result. Bay's always been an easy player to root for. He's sacrificed his body and health on multiple occasions in order to track down fly balls in left field, and he's been pretty honest about his struggles in public. There's no real reason to boo the guy at Citi Field. If the Mets are more worried about what Bay might do with another team next year than what he might do with the Mets, though, they're doing it wrong.
