The Los Angeles Angels’ wild comeback win over the Boston Red Sox could provide the boost they need to close the gap in the AL wild-card race.

Kendrys Morales led off the Angels’ two-run 10th inning with a solo homer, and Los Angeles completed a threegame sweep by outlasting the Red Sox 14-13 on Thursday night.

Los Angeles overcame deficits of 6-0, 9-8 and 11-9 and ended the night 2.5 games behind the second-wild card spot in the AL.

Vernon Wells hit a solo homer to cut Boston’s lead to 11-10 in the ninth and then doubled in the run that proved to be the difference after Morales’ 16th homer of the season snapped a 12-12 tie in the 10th.

Wells admitted that his high shot that appeared to bounce off the top of the left field wall shouldn’t have been a homer.

Boston manager Bobby Valentine appeared surprised when told at his postgame news conference that the home run call was wrong.

“I didn’t know that,” he said, then sighed and lowered his head.

The Red Sox wasted a 6-0 lead, then rallied from deficits of 8-7 in the sixth and 12-11 in the ninth. But, closer Alfredo Aceves struggled after Boston was one out away from victory in the ninth. Aceves (2-8) gave up five runs and six hits in one inning, and the Red Sox lost for the 11th time in 15 games.

Ernesto Frieri (2-0) got the win after giving up a tying solo homer in the ninth to Cody Ross, his 19th of the season, and an RBI single in the 10th to Dustin Pedroia, who drove in five runs.

Frieri was charged with a blown save, but secured the win when he struck out Adrian

Gonzalez to end the 4-hour, 34-minute game.

With the score tied at 12, Morales jumped on an 0-1 pitch from Aceves for his 16th homer — just over the low right field fence. Erick Aybar followed with a single, knocking out Aceves. Wells hit an RBI double off Craig Breslow for the final run.

The Angels swept the Red Sox after being swept at home in four games by Tampa Bay before coming to Boston.

The Red Sox took an 11-9 lead in the eighth on RBI singles by Jacoby Ellsbury and Pedroia, but the Angels rallied in the ninth and regained the lead with Wells’ eighth homer and two-out, run-scoring singles by Torii Hunter and Mark Trumbo.

Angels starter C.J. Wilson, 0-5 in his last 11 starts, struggled again.

The Red Sox took a 1-0 lead in the first on a double by Pedroia and an RBI single by Gonzalez. They made it 6-0 in the second on run-scoring singles by Scott Podsednik and Ellsbury, and Pedroia’s 11th homer, a three-run shot.

But, Franklin Morales couldn’t hold the lead, giving up six of the Angels’ eight third-inning runs. Los Angeles had six hits, three walks and an error in the inning. Chris Iannetta and Hunter had two hits each, and every member of the Angels lineup except Trumbo got on base.

Two runs scored on basesloaded walks to Kendrys Morales and Wells. Seven consecutive batters reached base after two were out.
