Greene said his struggles this spring are a result of working on his mechanics, not lingering finger numbness he's been dealing with, MLB.com reports.
Blood circulation issues led to surgery two years ago for Greene, and the fingers on his right hand will still occasionally go cold or numb. However, he said he's gotten used to the feeling, and his struggles this spring are more due to mechanics. "I think what was happening was, for me, when I tell myself to stay back, I slow my arm down," Greene said. "All spring training I've been trying to get my arm to catch up. I finally stopped thinking about it, and it caught up, and everything felt great." The righty gave up seven runs on 11 hits over his first four innings this spring, but he's pitched five straight scoreless innings since.
