WASHINGTON, D.C. (CBSNewYork/AP) — Jose Lobaton hit a go-ahead sacrifice fly against his former team in the 12th inning and the New York Mets beat the Washington Nationals 5-4 on Thursday night.

Lobaton, who spent the previous four years in Washington before signing with the Mets in December, lofted a one-out fly ball off Jefry Rodriguez (3-3) with the bases loaded to score Amed Rosario.

Jacob Rhame (1-2) worked two scoreless innings, and Paul Sewald pitched the 12th for his second save.

Nationals outfielder Bryce Harper was ejected in the 12th for arguing home plate umpire D.J. Reyburn’s called third strike.

Michael Conforto smashed a two-run homer to left in the third, his 27th of the season. It was also his fourth home run in 23 career at-bats against Max Scherzer.

Four pitches later, Jay Bruce crushed his ninth home run of the season. It was the sixth time this season New York has hit back-to-back homers.

Mets manager Mickey Callaway was ejected in the 10th inning for arguing after Reyburn ruled McNeil had offered on a bunt attempt.

TRAINER’S ROOM

Mets: INF Wilmer Flores will miss the rest of the season with soreness in both knees. Callaway said Flores has early onset arthritis in both knees and will receive injections to alleviate the pain. “It’s not like surgery is recommended at this time,” Callaway said. “I think rest and a couple injections is supposed to knock this out pretty good.”

UP NEXT

NL Cy Young contender Jacob deGrom (8-9, 1.78 ERA), who is 5-1 with a 2.76 ERA lifetime at Nationals Park, gets the nod for New York as the four-game series continues.
