A's activate Reddick, place Blanks on 15-day DL
Manager Bob Melvin said Reddick felt great after testing his hyperextended right knee during a rehabilitation stint with Triple-A Sacramento. Reddick is starting in right field and batting seventh Tuesday night in the opener of a two-game series against the Mets.
Blanks has been nursing the calf injury for several days, and he had to leave Sunday's loss to Boston because it worsened.
Catcher Derek Norris was out of the lineup after being hit in the head by a backswing Sunday. Melvin said Norris felt he was fine to play. The A's, though, wanted to see how Norris went through pregame drills before determining what kind of role he could play against New York.
