Tests on Bert Blyleven's right shoulder showed no nerve damage, but he will undergo arthroscopic surgery on Tuesday to determine the cause of pain in his shoulder. Blyleven underwent arthroscopic surgery on the shoulder last October, shunning more extensive surgery. If additional damage is revealed Tuesday, Blyleven will have to have a more complicated operation.
Right-hander Matt Keough underwent surgery to repair a significant tear in his rotator cuff. The surgery was performed by Dr. Lewis Yocum at Centinela Hospital in Inglewood.
