TEMPE, Ariz. (AP) — Sure, Garrett Richards realizes his luck has been pretty bad the past couple of seasons when it comes to injuries. He's not interested in dwelling on all the time he missed, all the countless hours of rehab that seemed as if they'd never end, rather turning his attention to what he can do to help the Los Angeles Angels now that he's healthy at last. A year ago, 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 had stem-cell therapy instead of the more common Tommy John reconstructive surgery.
