All sports are paying more attention to concussions here recently and MLB is no different. Fortunately, there is not a high incidence of concussions in baseball, although you would not be able to tell that from watching the Mets. In 2012, there were nine concussions documented by The Concussion Blog from Opening Day to the All-Star break and two of those were suffered by members of the Mets.
Josh Thole suffered one in early May and Jason Bay had one in mid June. Unfortunately, it was not the first concussion for either player. Thole says he had previous concussions in the minor leagues in both 2007 and 2008. Meanwhile, Bay had a season-ending concussion injury in 2010, his first with the Mets.
Thole has been noticeably worse since his concussion while Bay has been worse off, too. Here are their pre and post-concussion splits:
Pre — .284/.356/.370 (92 PA)
Post – .224/.278/.265 (239 PA)
Pre — .187/.253/.373 (83 PA)
Post – .135/.222/.221 (117 PA)
