De La Rosa To Have Tommy John Surgery; Out 9-12 Months

(CBS) — In what may be the biggest blow of the season for the Dodgers, rookie sensation Rubby De La Rosa has a torn ulnar collateral ligament in his throwing elbow and will undergo Tommy John surgery.

 The ligament replacement operation requires nine to 18 months of rehabilitation.

The 22-year-old routinely hits 100 mph with his fastball.

Tommy John surgery was first performed by Dr. Frank Jobe on Dodgers pitcher Tommy John in 1974.

Last August, Washington Nationals star Stephen Strasburg had the surgery and his velocity has almost fully returned, hitting 95 mph in a bullpen session.

Strasburg is pitching a simulated game on Tuesday and if that goes well, he could pitch this season for Washington.
