Kielty on the DL

I thought Bobby Kielty was robbed out of spring training, of course, I'm bias I always pick an underdog to root for in spring training and Kielty had the potential to be my first correct pick. But the Mets with a lefty heavy line-up chose to go with left handed hitting Marlon Anderson who was hitting a mere .220 instead of Kielty a righty hitting around .280. Of course, that became a moot point when the team signed Sheffield and after just over a week in AAA Keilty is on the shelf. So far I can't find the nature of the injury or the severity.....
