ANAHEIM, Calif. -- Nick Tropeano will become the second Los Angeles Angels starter this season to have Tommy John surgery, while ace Garrett Richards will continue stem cell treatments on his injured elbow after seeing positive results.
Los Angeles general manager Billy Eppler announced that after considering more conservative treatments -- including stem cell treatments -- the right-handed Tropeano has elected to have surgery to repair his torn ulnar collateral ligament. Andrew Heaney had Tommy John surgery in July, and C.J. Wilson hasn't pitched all season due to various elbow and shoulder injuries, and was shut down July 5 to have shoulder surgery.
