Mets LHP Steven Matz had successful surgery on Wednesday to move the ulnar nerve in his left (pitching) elbow, the team said.
MRI and CT scans on Monday led to a diagnosis of irritation of the ulnar nerve, and surgery repositioned the nerve to address the irritation, the team said.
Mets RHP Jacob deGrom had the same surgery last September and returned for spring training.
Matz pitched through pain this season, Newsday reported earlier this week, citing sources. He reportedly had been altering and/or skipping bullpen sessions to prevent the issue from worsening.
The 26-year-old Matz, who missed the first two months of the season due to an arm/elbow injury, has a 6.08 ERA and 1.53 WHIP with 48 strikeouts in 66 2/3 innings (13 starts) this season.
