Mike Pelfrey, Maine's close friend, spoke with the injured right-hander by telephone on Wednesday after Andrews had completed his examination.
"He was pumped," Pelfrey said. "They told him there's nothing structural. He'd been worried he could make it worse. But it's just weak. They told him he came back too fast [from the fall surgery on the shoulder]."
Maine, assigned to the disabled list since June 7, was examned by Andrews in Birmingham, Ala. He is to continue the treatment and rehab programs he has followed for weeks.
Pelfrey mentioned the pain is caused by what is thought to be a pinched nerve in the shoulder. Weeks ago, some people in the organization said Maine might never pitch again without pain. Pelfrey acknowledged that Maine has been talked to about pitching with pain tolerance. The pain he has experienced isn't a constant, Pelfrey said.
