The American League Championship Series was tied up at one game apiece after a David Ortiz grand slam helped the Red Sox to an astonishing comeback, winning against the Detroit Tigers.
Everything looked on course for the Tigers to take a 2-0 lead in the seven game series as the tie entered the eighth innings with Detroit leading 5-1.
Max Scherzer had frustrated Boston for most of the evening with an inspired performance from the mound but finally gave up a hit in sixth.
Overall, a seven innings stint saw him achieve 13 strikeouts, giving up two hits, two walks and one run.
It was a performance worthy of a winning team.
But at the bottom of the eighth with the bases loaded for the Red Sox, Ortiz smashed a game-tying grand slam off of a devastated Joaquin Benoit.
It was only the third game-tying grand slam in post-season history and it inspired Boston to go on a win the game and send Fenway Park in to raptures.
An out-of-sorts pitch from Rick Porcello gifted third base to Jonny Gomes in the ninth, setting up Saltalamacchia to hit a simple single to win the game.
After the game Scherzer praised his counterpart Ortiz for turning to game around.
"That's what he [Ortiz] does. He's an amazing hitter," he told reporters. "He's an amazing postseason hitter. He's clutch. Any given moment, a swing of the bat he can always take you deep."
