OAKLAND -- The A's won't see Jharel Cotton pitch again this season.
Instead of starting against the Rangers on Friday, the rookie right-hander will be limited to an extended bullpen session before his offseason begins. Cotton underwent an MRI on his pitching elbow Monday that came back clean.
"He's healthy, and we want to make sure he stays healthy," A's manager Bob Melvin said. "It just doesn't seem like it's worth the risk of having him go out there this late in the season, throwing 100 pitches and potentially getting a little bit sore again.
