The Boston Red Sox once again handed the New York Yankees a demoralizing loss at Fenway Park with a thrilling comeback Sunday afternoon. 

The Yankees hadn’t surrendered a hit and led 4-0 entering the eighth inning. And that’s where it all fell apart for New York.

Five consecutive Red Sox hits, an RBI groundout and a sacrifice fly resulted in a five-run eighth inning for Boston. 

Check out the highlights from the pivotal eighth inning in the video below:

Matt Barnes picked up his 21st save of the season with a scoreless ninth inning as the Red Sox emerged with a 5-4 win.

It was the second comeback victory of the series for the Red Sox. They also staged an exciting comeback in Thursday's 10-inning win. Yankees manager Aaron Boone called that loss a "gut punch."

The Red Sox now lead the Yankees by nine games in the American League East standings, but their advantage over the second-place Tampa Bay Rays is still only a single game.
