Diamondbacks' De La Rosa to have stem cell injection (Yahoo Sports)

Arizona Diamondbacks right-hander Rubby De La Rosa is trying to avoid a second Tommy John surgery by having a stem cell injection in his ailing elbow. Manager Chip Hale said De La Rosa met with Dr. James Andrews and decided to try the stem cell injection instead of another major surgery. Hale didn't have a timeframe for De La Rosa's return other than he will miss the remainder of the season.
