HOUSTON -- Rehabbing A's right-hander Jarrod Parker is nearing live game action, after throwing three simulated innings in extended spring camp on Monday.
Parker, who underwent his second Tommy John surgery last spring, totaled 45 pitches, according to manager Bob Melvin, and allowed one run on three hits with one walk and one strikeout while averaging 92 mph on his fastball.
Melvin said Parker will throw a bullpen ahead of his next outing, which could potentially be a Minor League game.
The righty has been targeting June 1 as a return date to the A's rotation. A.J. Griffin, also on the comeback trail from Tommy John surgery, is also expected to be cleared at some point during that month.
