NEW YORK (AP) ― The Red Sox salvaged their AL wild-card lead Sunday when Jacoby Ellsbury hit a two-out, three-run homer in the 14th inning of the nightcap of a day-night doubleheader, lifting Boston over the New York Yankees 7-4.

The Red Sox rallied from a 3-0 deficit to snap a four-game skid and head into their final series with a one-game lead over Tampa Bay.

Boston held a nine-game lead over the Rays entering play Sept. 4 but has gone 5-16 since then. Up by 1 1/2 games to start the day, the Red Sox nearly wasted that entire lead after losing the opener 6-2 despite Ellsbury’s two homers. Combined with the Rays’ 5-2 win over Toronto, the Red Sox went into the second game with a half-game lead.

Boston finishes in Baltimore, while Tampa Bay hosts the Yankees, who already have clinched the AL’s best record and homefield advantage through the AL championship series.

“I hope we were breathing before ― every other breath. It was a BIG win, but we’ve got to go down tomorrow and play well,” Red Sox manager Terry Francona said.

Ellsbury homered off Scott Proctor (0-2) after Darnell McDonald singled and Marco Scutaro walked.

Franklin Morales (1-1) pitched two innings for the win. Felix Doubront, recalled on Sept. 1, finished the 5-hour, 11-minute game for his first save since August 2010.

In the opener, A.J. Burnett made his most impressive start in nearly three months and Jorge Posada hit a two-run homer for the Yankees. Ellsbury connected twice to become the first player in Red Sox history to reach 30 homers and 30 stolen bases in a season.
