A's pitcher Brett Anderson is still feeling soreness in his sprained right ankle and won't be activated from the disabled list when he becomes eligible Thursday. There was hope that he could start Friday's game against the Kansas City Royals, but after testing the ankle Tuesday, Anderson reported still feeling soreness and will remain out of action for "the foreseeable future," manager Bob Melvin said.. Anderson threw a bullpen session Tuesday and joined pitchers for fielding practice. He felt fine while throwing off the mound, but the drills on the field is what led to the soreness. "We're not at the point where we're comfortable putting him out on a big league mound again and going through what we had to the last couple of times," Melvin said. Jarrod Parker will make what amounts to a regularly-scheduled start on Friday when the A's open a three-game series with the Royals.
