Heres what I just read:
From the The Sports Xchange: Center fielder Jordan Schafer clearly earned his spot on the season-opening roster and in the starting lineup. But he never spent a day at Triple-A and he missed 50 games at Double-A last season because of an HGH suspension. Add to the fact he had never played in any major league park until this season or faced that many major league pitchers (other than those he saw in limited innings in spring training) and there are going to be growing pains. That would be in addition to an actual pain: Word is Schafer hurt his left wrist to some degree during the opening series in Philadelphia, but he won't talk about it.
