Red Sox clinch third straight AL East title

Mookie Betts and the Boston Red Sox won their third consecutive AL East championship Thursday night, clinching on enemy turf with an 11-6 victory over the rival New York Yankees.

Betts homered, doubled twice and drove in five runs, finishing with four hits as the Red Sox overcame Giancarlo Stanton’s goahead grand slam in the fourth inning. Jackie Bradley Jr. hit a tying home run in the seventh and Xander Bogaerts put Boston ahead with a sacrifice fly.

With the best record in baseball and a playoff berth already secured, Boston (104-49) closed out a once-tight division race with nine games to spare. J.D. Martinez and the Red Sox, alone in first place since July 2, will open the post-season at home on Oct. 5 against an opponent to be determined.

Never before had Boston finished in first place three years in a row. The club needs one victory to match the franchise record held by the 1912 World Series champions.

It took three tries, but these Red Sox finally earned their chance to celebrate at Yankee Stadium under rookie manager Alex Cora.

Boston entered the three-game series needing a single victory to lock up its fourth AL East title in six years, but the Yankees put the party on hold for a few nights with two straight wins.

Craig Kimbrel whiffed a slumping Stanton for the final out, and the Red Sox strolled out of the dugout to give each other hugs and high-fives in a muted celebration around the mound. They walked off the field and headed inside to cheers from Boston fans behind the third base dugout.

Then, it was time to break out the bubbly in the Bronx.

Two years ago, in David Ortiz’s final season, the Red Sox celebrated in the visitors’ clubhouse at Yankee Stadium after wrapping up the division crown in New York. But that came in the wake of a loss — after Mark Teixeira’s game-ending grand slam gave the Yankees a comeback win.

About 30 minutes earlier, the Red Sox had clinched when Toronto lost to Baltimore. So they went ahead and celebrated their season accomplishment with a booze-filled fiesta.

This time, they got to do it absolutely right.

After starter Eduardo Rodriguez walked a career-high seven in 3 2/3 innings, knuckleballer Steven Wright (3-1) worked three shutout innings for the win.

Brock Holt also homered for the Red Sox, and Martinez increased his major league-leading RBI total to 124 in a game that took 4 hours, 2 minutes.

Betts, a top contender for AL MVP, opened the game with a double off the left-field fence against Masahiro Tanaka and scored on Martinez’s single. Betts added a two-run single in the second, then doubled and scored in the fifth.

Bradley tied it 6-all with a leadoff homer in the seventh against Chad Green (8-3). Christian Vazquez singled, and Boston loaded the bases before Bogaerts delivered his sacrifice fly. Another run scored on the play when centre fielder Aaron Hicks was charged with a throwing error.

Betts launched his 30th home run in the eighth, a three-run shot off All-Star closer Aroldis Chapman, who was activated from the disabled list Wednesday.

Luke Voit hit a two-run homer for New York.
