Add another name to the list of the hard-throwing young pitchers needing Tommy John elbow surgery, as Dodgers reliever Chris Withrow has been diagnosed with a torn ulnar collateral ligament and is headed under the knife.

Withrow has been fantastic since debuting for the Dodgers last season at age 24, posting a 2.73 ERA with 71 strikeouts in 56 innings while holding opponents to a .157 batting average. It doesn’t get much more dominant than that, especially when combined with a 95.7-mph average fastball.
