The Boston Red Sox moved to within a game of winning the World Series as they took a 3-1 lead over the Los Angeles Dodgers after a late rally secured victory in game four.

A day after the longest game in World Series history, the Red Sox moved closer to their ninth title with a 9-6 triumph at Dodger Stadium.

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.
