Adam Eaton (elbow) will hit in the batting cage Thursday. He will hit off a tee and have balls flipped to him at extended spring training. It's the first bit of action for Eaton since he was shut down a little over two weeks ago with a UCL sprain in his left elbow. "I know he's excited to do that," D'Backs manager Kirk Gibson said. "He's really champing at the bit." Eaton is still at least two weeks away from throwing a ball and won't return until mid-to-late May.
