The game-winner led off the bottom half of the 18th inning and came off of Nathan Eovaldi, who was suppose to start Saturday's Game 4 for Boston. Eovaldi was pitching in his third straight game out of the bullpen and threw nearly 90 pitches over six innings, as Muncy's long ball was the only run charged against him in the loss.
The Red Sox trailed by one for a majority of "regulation" as Walker Buehler dominated in the start for the Dodgers, but it was Kenley Jansen who surrendered the lead out of the bullpen. The reliever gave up the tying solo home run to Jackie Bradley Jr. in the eighth inning, which was his third home run of the Postseason, all of which have either given his team the lead or tied the game.
Boston had another shot to win the game in the the 13th inning when they jumped ahead by one on an errant throw from reliever Scott Alexander at first base. That would score Brock Holt from second base and make it look as if the Red Sox were going up 3-0, a lead that has never been given up in World Series history. But a half-inning later, with a runner at second, Yasiel Puig reached on an errant throw from Ian Kinsler, which scored Muncy from second base.
The game would last five more innings, as the two teams combined to use 46 players, 18 pitchers, and threw 561 pitches on this night. Before Friday night, a World Series game had never lasted longer than 14 innings, but the Dodgers ended it with their first World Series walk off since Kirk Gibson's game-winner in Game-1 of the 1988 series. These two teams will do battle again Saturday night in Game 4, but neither team has announced a starter for the contest.
