It was the 6th game of the best-of-seven series. Going into the game, Boston was leading 3 games to 2.
It appeared that Boston was going to win their first championship since 1918 when the Mets came to bat in the bottom of the 10th inning behind 5 runs to 3.
With 2 outs in the bottom of the 10th, Mets catcher Gary Carter singled to left field. Pinch hitter Kevin Mitchell singled to center. Third baseman Ray Knight then hit a single that scored Gary Carter and advanced Mitchell to third base. The score is now 5-4 Red Sox. The Red Sox replaced pitcher Calvin Schiraldi with Bob Stanley to face left fielder Mookie Wilson. Kevin Mitchell scored on a wild pitch, which also moved Ray Knight to second base. The score was now tied, 5-5. Wilson then fouled off a few pitches, then he hit a little roller up along the first baseline, which went through the legs of Red Sox first baseman Bill Buckner. Ray Knight scored from second and the Mets won the game.
Two days later, they won the 7th and deciding game of the series.
