Kluber (back) will throw off a mound Monday, Jordan Bastian of MLB.com reports.
This is a sign of progress for the former Cy Young winner, although he's only expected to throw 20 pitches or so. This means Kluber is still a ways away from a return to the rotation (or a rehab assignment, for that matter), but the Indians' plans for him should become clearer as he ramps up his activity.
