Detroit Tigers top pitching prospect Casey Mize left Thursday night's start in Double A Erie due to an apparent shoulder injury.

Casey was the number 1 overall draft pick out of Auburn by the Tigers last year, and he is currently undefeated on the season for the Erie Seawolves in the Eastern League, in addition to his short stint with High-A Lakeland of the Florida State League.

Mize is one of the top prospects in all of baseball.  He threw a no-hitter in his first start for Erie earlier this season.
