Danny Duffy (elbow) will throw off a mound Tuesday for the first time since undergoing Tommy John surgery last June. It will only be a 20-pitch soft-toss session, but it's certainly a step in the right direction. Duffy will likely return sometime around the All-Star break if his recovery goes smoothly. The southpaw has the talent to become a mixed league option in the second half, but he probably won't be back to his regular self until 2014.
