Boston Red Sox defeat LA Dodgers in Game 4

The Dodgers looked on course to level the series as Yasiel Puig smashed a three-run homer in the sixth inning, leaving the Red Sox facing a 4-0 deficit going into the seventh.

But pinch-hitter Mitch Moreland responded with his own three-run home run in the seventh to spark a Boston revival.

Steve Pearce proved to make the difference, hitting a home run in the eighth, levelling the score at 4-4.

Five runs came in the ninth - including a three-run double from Pearce and a go-ahead single from Rafael Devers - with Xander Bogaerts adding an insurance RBI single to see out the victory.

Game Five is Sunday at Dodger Stadium, where the Red Sox can win their fourth title in 15 years.
