The Red Sox now hold a 9.5 game lead over the Yankees.
Betts, who had to move to the outfield coming up through the system because the Red Sox had a second baseman in Dustin Pedroia, was happy to return.
The Yankees could be forgiven for getting a little comfortable in the 9th inning.
"Miguel I feel like is equipped to deal with the successes and failures that you inevitably have up here, so I don't worry about putting him back out there", Boone said before the win. Kind of stole this one. Boston will have a lot of pressure to win it all this postseason and it is quite possible they will face the New York Yankees in the ALDS and the Houston Astros would face the Cleveland Indians. Instead, it has all but won the division for Boston, relegating the Yankees to the wild-card race.
Boston's 79-34 record gives them a.699 winning percentage, which would be the highest in franchise history.
Of course, even if the Yankees pull out a series-salvaging victory, there will still be a 7 1/2 game gap in the Major League Baseball standings between the two teams.
"A tough way to obviously end a tough weekend, but we can't let this define what's been a great season", manager Aaron Boone said.

That play was the culmination of an epic flush job by Yankees closer Aroldis Chapman, who entered the game with 29 saves in 30 opportunities, but proceeded to walk three of the first five batters in the ninth, setting the stage for the tie and inevitable 10th inning walk-off base hit by Andrew Benintendi off middle reliever Jonathan Holder. Severino for a while was competing for the American League Cy Young Award, but in his last three starts he has given up 17 runs in just 15 innings. Stanton followed with an RBI single and Gleyber Torres had a sacrifice fly. The 23-year-old Adams is 3-5 with a 4.50 ERA in 21 starts with Scranton/Wilks-Barre, but he's been better than that lately, with a 3.07 ERA over his past six starts.
Rafael Devers who was put on the DL with a left hamstring strain is also working his way back to the majors. The team did not say when Sale would make his next start. The hit was originally ruled a foul ball, but the call was overturned when the Red Sox challenged.
Boston rallied from a 0-3 series deficit in the 2004 ALCS en route to winning its first World Series since 1918. "Tomorrow is always important", NY manager Aaron Boone said.
Boone can get Didi Gregorius and other everyday players the rest he has been trying to give them. We've got to right the ship.
As if that was not exciting enough for Red Sox fans, we've got positive injury updates on both Eduardo Rodriguez and Rafael Devers.
