Wall is out for the rest of the season after dislocating his left (non-throwing) shoulder in a game for High-A Lancaster earlier this month, Bobby DeMuro of BaseballCensus.com reports.

EDGE Analysis

It is now clear why Wall has not played since May 2. On the surface, it appeared that he was really playing well in a repeat run at High-A, slashing .299/.361/.471 with three home runs and five steals (on eight attempts) in 87 at-bats. However, the fact that he was slashing just .222/.237/.444 away from the extremely hitter-friendly conditions at Lancaster suggests that his surface numbers may not truly indicate how well he was playing prior to the injury.
