TODAY: deGrom’s procedure was completed successfully today, the Mets announced. His ulnar nerve was “reposition[ed]” during the surgery, and the expectation remains that he’ll be ready to go next spring.

YESTERDAY: Mets right-hander Jacob deGrom will undergo surgery on the ulnar nerve issue in his right elbow later this week, reports ESPN New York’s Adam Rubin. The operation, which will move the nerve to alleviate the discomfort deGrom has been feeling, comes with a three-month recovery, Rubin adds.

Obviously, the operation will bring deGrom’s season to a close and rule him out of the Mets’ postseason rotation picture (if New York is able to hang onto the Wild Card spot it currently holds). The 28-year-old former NL Rookie of the Year (2014) was able to start just 24 games for the Mets in 2016 but was quite productive when on the mound even in spite of the nerve issue in his arm. DeGrom totaled 148 innings of 3.03 ERA ball this season, averaging 8.7 K/9 and 2.2 BB/9 to go along with a 45.6 percent ground-ball rate. He entered the season with one year, 139 days of Major League service time, making him a very likely Super Two candidate following the season.

DeGrom becomes the latest Mets starter to go down with an arm injury in what has been a difficult year for New York’s vaunted young rotation. Zack Wheeler was never able to make it back to a big league mound as he recovered from 2015 Tommy John surgery but incurred numerous setbacks along the way. Matt Harvey, meanwhile, underwent surgery to alleviate thoracic outlet syndrome after struggling through the first half of the regular season. Both Steven Matz and Noah Syndergaard are pitching through bone spurs in their throwing elbows as well, though Syndergaard’s is considered much more minor in nature. And if the bone spur wasn’t enough, Matz has also been battling tightness in his left shoulder, which has sidelined him for the past month, though he’s nearing a return from the disabled list.
