ESPN’s Adam Rubin reports that Mets starter Jacob deGrom will undergo surgery later this week to address the ulnar nerve in his right elbow. He’s expected to need three months to recover.

deGrom has had a great season, owning a 3.04 ERA and a 143/36 K/BB ratio in 148 innings. The elbow started to become bothersome in mid-August, however. He was unable to make it past the fifth inning in his previous three starts and he gave up 16 earned runs over 14 2/3 innings.

It’s rough but not unexpected news for the Mets, who are one game up on the Giants and Cardinals for the first Wild Card slot in the National League. Their current top-three includes Noah Syndergaard, Bartolo Colon, and Seth Lugo.
