Tim Stauffer (elbow) threw a bullpen session Tuesday and is scheduled to throw another one this weekend. It was the first time since his elbow injury that he was able to throw off a mound. Stauffer is coming along, but he's still at least a couple of weeks away from activation. Anthony Bass or Joe Wieland will be booted from the rotation once Stauffer is ready.
