Left-hander Matt Harrison won't pitch again this season after doctors determined that his back, operated on twice in April and early May, isn't strong enough to allow to pitch without running the risk of suffering an arm injury.
Harrison had complained of numbness in his hand Friday during his third rehab start and was removed in the fourth inning. He also had some elbow soreness, and agree that his back wasn't as strong as he had hoped.
"He had done so well the last month," general manager Jon Daniels said. "Based on that, I was expect him to come back. ... Until somebody's back, there's always some risk."
The Rangers' rotation depth is now very thin. The Rangers expect Nick Tepesch (elbow) to return in September. If a starter is needed before then, Ross Wolf, Josh Lindblom, Jake Brigham and Evan Meek would be candidates for a spot start or two.
The Rangers will continue to look outisde the organization for help, but don't expect to land an impact pitcher.
"We don't have the depth we'd like to have if there is an issue," Daniels said. "It's most concerning if we have another issue."
