“During surgery, we fix everything that’s damaged,” Ahmad said. “If the capsule is torn, we fix the capsule. If the labrum is torn, we fix the labrum. If the shoulder is extremely loose in general, we will tighten everything up with the stitching.”
Following surgery, the player does not swing a bat for three months and typically returns to play in four to six months. So if Conforto had surgery immediately, a return in time for Spring Training would be realistic. Recovery could also be slightly easier and/or faster, because Conforto throws right-handed.
