Orioles prospect Luis Lebron underwent Tommy John elbow reconstructive surgery on Tuesday in Alabama.
Lebron, 25, had not thrown a pitch this season. He finished 2009 with a 2.54 ERA, 1.01 WHIP and a 91/33 K/BB ratio in 52 relief appearances between Single-A Frederick and Double-A Bowie. Hopefully he can get back on track once his recovery is complete -- probably around next August.
