OAKLAND -- A's reliever John Axford landed on the 10-day disabled list Wednesday with a strained right shoulder after experiencing discomfort while warming up during Tuesday's game against the Angels.
"It was a complete surprise, not only to us but to him," A's manager Bob Melvin said.
It's the first career DL stint for the eight-year veteran, who was scheduled to undergo an MRI on Wednesday afternoon to determine the severity of the injury. Right-hander Jesse Hahn was recalled from Triple-A Nashville to take his place on the roster, giving Melvin an additional long-relief option in the bullpen.
