Flame throwers: The 25 hardest-throwing MLB pitchers

Known for his unbelievable velocity while in college at Tennessee, Joyce is showing flashes of a potential closer this season with a fastball that's averaged 101.5 mph. If he can throw strikes, Joyce has a chance to pitch at the end of games for the Angels soon.

Uribe began the season as part of Milwaukee's closer committee, but poor control pushed him to the minors in early May. He has huge potential if he can harness a fastball that averages 100.1 mph.
