On October 25, 1986, in Game 6 of the World Series, the New York Mets faced the Boston Red Sox at Shea Stadium. The Red Sox were leading the series 3-2 and were just one out away from winning their first World Series since 1918.
With the Red Sox leading 5-3 in the bottom of the 10th inning, the Mets' catcher Gary Carter singled to left field to start a rally. Kevin Mitchell, the next batter, singled to center, advancing Carter to second. Ray Knight followed with another single, scoring Carter and moving Mitchell to third, narrowing the Red Sox lead to 5-4.
The Red Sox replaced pitcher Calvin Schiraldi with Bob Stanley to face Mookie Wilson. During Wilson's at-bat, Stanley threw a wild pitch, allowing Mitchell to score from third and tie the game at 5-5. The wild pitch also advanced Knight to second base.
With a 2-2 count, Wilson hit a slow roller up the first base line. Red Sox first baseman Bill Buckner, known for his solid fielding, misplayed the ball, allowing it to roll between his legs and into right field. Ray Knight scored from second base, giving the Mets a dramatic 6-5 walk-off win and forcing a decisive Game 7.
The Mets went on to win Game 7, 8-5, clinching their second World Series title. Bill Buckner's error became one of the most infamous plays in baseball history, and the game itself is considered one of the greatest in World Series history, with its dramatic comeback and unlikely ending.
