Carl Crawford believes he is 7-10 days away from picking up the pace in his rehab work. The Red Sox outfielder is out with left elbow and left wrist issues. He was shut down April 26 because of a partially torn ulnar collateral ligament in his elbow. "It would be swinging a bat before throwing," Crawford said. "It's frustrating being out, but I want to make sure I don't have any setbacks with it."
