Angels’ Garrett Richards opts for stem-cell therapy instead of surgery
Angels ace Garrett Richards, who suffered a high-grade tear of his ulnar collateral ligament in early May, has opted to forgo ligament-replacement surgery — for now — in favor of stem-cell therapy in hopes of pitching again this season.
Richards underwent the procedure, in which stem cells are derived from bone or fat and injected into the injury site in hopes of repairing and regenerating the damaged ligament, on Monday. There is no guarantee the procedure will be successful, but doctors should know in six to eight weeks if it is.
Richards, who went 1-3 with a 2.34 earned-run average in six starts, had all but resigned himself to Tommy John surgery, which would have sidelined the hard-throwing right-hander for the rest of this season and most, if not all, of 2017.
If stem-cell therapy, which Eppler termed a “conservative care route,” doesn’t work, Richards, 27, could have surgery in July and be ready for 2018.
“He got input from numerous sources, both players and doctors, and felt this was the best course of action … to heal and get healthy,” Manager Mike Scioscia said. “I don’t think you want to jump into any kind of surgery, let alone one the magnitude of Tommy John surgery.
“That puts you out for this season and most of next season. Garrett has a few months to evaluate where his elbow is. He really isn’t having many symptoms at all, so I know he’s confident with this course of action.”
Eppler said there are pitchers “who have had this procedure and are pitching well in the big leagues,” but he declined to name any.
If the treatment is successful, Richards could resume throwing by mid-July and return sometime in August. Fellow pitcher Andrew Heaney also opted to forgo elbow surgery in favor of a platelet-rich plasma injection in April.

The left-hander hopes to return by mid-June. “He looked good for a first workout against some hitters,” Scioscia said. “It’s encouraging, but it’s still a long process.” …
