The target time for him to get back on the mound is sometime in June, and he hopes that he can rejoin the team before the end of the season.
"It's not up to me, but I'd like to get back at some point this year, whether it's for a week or a month," he said.
There is still a ways to go before then, but when you've missed as much time as he has, you'll take any ray of hope you can get.
"I feel like I'm starting to get to the point where I'm seeing the light at the end of the tunnel," he said.
