Corbin is recovering from Tommy John surgery, and is already in Arizona at the team's spring training facility. He was actually able to play catch at the end of last season, but decided to take two months off during the offseason. He started throwing again in January.
"When I first started throwing, it wasn't feeling the best, there was just different things in there," Corbin said. "But after I took those two months off, when I started up again, everything felt great. Now when I throw, it feels good."
The typical recovery from Tommy John is about 12 months, but the Diamondbacks will take things slower after seeing pitcher Daniel Hudson re-tear his UCL after trying to return too quickly from the surgery.
Corbin will continue to participate in a throwing program until he's able to comfortably throw from 150 feet. At that point, he'll be able to start throwing flat ground bullpen sessions. Corbin said he's probably looking at a June return, but could push to move quickly once he gets back on a mound. "Everybody is telling me that they're going to take it slow and it will be somewhere around June," he said. "We'll just see how it starts going when I actually get back on a mound."
