NEW YORK — Mets right-hander Jacob deGrom has been scratched from his scheduled start Sunday and is unlikely to pitch again this season because of an injury to the ulnar nerve in his right elbow.

DeGrom has been out since Sept. 1 after experiencing elbow pain in a start against Miami. He felt fine while throwing a bullpen Friday, then had pain while lobbing a baseball in from the outfield during batting practice about 15 minutes later.

General Manager Sandy Alderson announced the injury Saturday. DeGrom will need surgery but the 2014 NL Rookie of the Year has not decided whether he will wait until the end of the season to have it. The recovery time for the surgery is expected to be three months.

Gabriel Ynoa will start Sunday against Minnesota, and Manager Terry Collins says he expects to use his bullpen to cover a lot of innings.

INDIANS: Catcher Yan Gomes will miss six to eight weeks with a broken right wrist, likely ending his injury-plagued season.

Gomes sustained a non-displaced fracture when he was hit by a pitch Wednesday night while on a rehab assignment for Double-A Akron. He was examined by a hand specialist Friday and will not need surgery.

Gomes appeared to be a game away from rejoining the Indians when his latest injury occurred. He separated his right shoulder on July 17 when he fell trying to beat out a play at first base in Minnesota.

BREWERS: Right-hander Junior Guerra’s season has been ended by Milwaukee because of an innings limit.

The 31-year-old rookie went 9-3 with a 2.81 ERA in 20 starts and 1212/3 innings. He was on the disabled list from Aug. 8 to Sept. 2 because of right elbow inflammation and was 2-0 with a 1.88 ERA in three starts since his return.

“He finished exactly the way we wanted him to finish coming off the injury,” Manager Craig Counsell said Saturday.

Milwaukee also recalled outfielder Michael Reed from Triple-A Colorado Springs on Saturday to help fill a gap created by injuries to outfielders Keon Broxton and Kirk Nieuwenhuis.

Broxton will miss the remainder of the season after breaking his right wrist on Friday when he slammed into Wrigley Field’s left-center field wall tracking down a line drive. Nieuwenhuis replaced Broxton, then left due to an abdominal strain.

NATIONALS: Manager Dusty Baker expects Joe Ross to return from the 60-day disabled list Sunday and make his first start since July 2.

Baker will keep Ross on a pitch count, probably no more than three innings, when Washington closes a three-game series against the Atlanta Braves.

Ross has been sidelined with right shoulder inflammation. He went 7-4 with a 3.49 ERA in 16 starts before getting hurt.

With a magic number of six to clinch the NL East, Baker wants to use the last two weeks of the regular season to set up his rotation for the playoffs, but Ross’ role is uncertain.

“We’ll see how his arm feels,” Baker said. “Then we’ll increase the workload as he can or maybe see how he does out of the pen. It’s just important to us that he gets on a mound and in a game before we start worrying about what we can expect from him.”

Max Scherzer, Tanner Roark and Gio Gonzalez are set as the top three with two-time All-Star Stephen Strasburg sidelined with a strained flexor mass in his right forearm. He hasn’t made a start since lasting 21/3 innings in a Sept. 7 start against the Braves.

ROYALS: Right-hander Nick Tepesch, who was designated for assignment, cleared waivers and Royals sent him outright to Triple-A Omaha. Tepesch, who is a Missouri alumnus, is 7-15 in 35 games, including 33 starts, in the majors with the Rangers and Dodgers.
