ALLENTOWN - Tommy Joseph's difficult start at triple-A Lehigh Valley now includes a concussion.
The Phillies' top catching prospect suffered the injury May 4 against Indianapolis and he has not played since. Joseph, 21, is hitting .209 with one double, three home runs, and 14 RBIs. He also has been charged with nine passed balls.
"He was probably the one guy who had more on his plate than anyone," director of player development Joe Jordan said. "That's just because of the position. He's got work to do defensively, offensively. We're very excited about him as a young prospect, but you start running the staff as a young guy in this league and obviously trying to not take your at-bats behind the plate."
