FILE - In this Sept. 17, 2017, file photo, Los Angeles Angels pitcher Garrett Richards works against the Texas Rangers in the first inning of a baseball game in Anaheim, Calif. Richards is not interested in dwelling on all the time he missed, all the countless hours of rehab, rather turning his attention to what he can do to help the Angels now that he's healthy at last. Last year, Richards had prepared to pitch for a full season after working his way back from a torn ulnar collateral ligament in his elbow for which he underwent stem cell therapy instead of having the more common Tommy John reconstructive surgery. Then he was hurt again in his season debut. (AP Photo/Reed Saxon)
