Joba continues rehab program, throwing off half-mound

Via the AP, Joba Chamberlain has started throwing off a half-mound as he continues his rehab from Tommy John surgery. He’s been throwing off flat ground for a few weeks, but now he’s starting to get elevated. He’s right on schedule based on Mike Dodd’s classic TJS article, and should begin throwing breaking balls pretty soon. Joba figures to return to the team in mid-June, a year out from surgery.
