BOSTON — Mookie Betts doesn't seem to be badly hurt, so the Red Sox can focus on clinching the AL East at Yankee Stadium for the second time in three seasons.
Betts gave Boston a scare when he injured his left side making two throws to home plate during a 4-3 win over the Mets on Sunday that cut Boston's magic number to two for a third straight division title.
"It kind of flared back up on the second throw. It'll be fine. I'll be ready to play Tuesday," Betts said. "I was just coming out for precautionary (reasons) just to make sure it didn't get worse. Everything checked out fine and I'll be ready to go."
Boston has an 11½-game lead over the second-place Yankees and would clinch with one win during a three-game series that opens Tuesday afternoon.
Betts, hitting .337 with 29 homers and 72 RBI, caught a fly ball from Jeff McNeil in the sixth inning and threw home as Austin Jackson held at third. Wilmer Flores followed with another drive to right, and Betts unsuccessfully threw home as Jackson scored on the sacrifice fly.
Betts went down to one knee, and the three-time All-Star was stretching his left side and back as a team athletic trainer and Cora jogged to the outfield. Betts walked off slowly and was replaced. Cora said Betts will get treatment Monday.
Andrew Benintendi hit a tie-breaking sacrifice fly in the eighth inning off Seth Lugo (3-4) after a matchup of Sale and the Mets' Jacob deGrom, both Cy Young Award candidates. Brandon Workman (5-0) pitched a scoreless eighth, and Steven Wright got three outs for his first big-league save.
DeGrom gave up three runs and five hits over seven innings with 12 strikeouts and one walk, his major league-leading ERA rising slightly to 1.78. He has gone a major-league record 27 straight starts holding opponent to three or fewer runs, according the Elias Sports Bureau.
Boston took a 3-0 lead in the third on Betts' sacrifice fly and Brock Holt's two-run homer. The Mets closed to 3-2 in the sixth on Flores' sacrifice fly and a double by Michael Conforto that bounced off the glove of Tzu-Wei Lin, who replaced Betts.
"I knew I had good stuff," deGrom said. "I made a couple mistakes that inning, just had to turn the page and go out there and try to keep us in the game. We tied it up and we were in the game the whole way."
