In July, 2016, Mets RHP Matt Harvey had season-ending surgery for thoracic outlet syndrome, which was done to restore feeling in his pitching arm and fingers.
According to former Mets GM and SNY analyst Jim Duquette, Harvey is not yet throwing off a mound, but he's feeling strong, on schedule with his post-surgery, off-season throwing program and will be 100 percent ready for spring training.
"He's had a great deal of time to work out and focus on his body and strength. We expect him to come back and be the Matt Harvey of old," his agent, Scott Boras, told reporters in early November at MLB's GM Meetings.
