10. The Boston Massacre
This is not a moment, but more of a period of collapse. Nevertheless, it owns a place in Yankees-Red Sox History.
Boston owned an enormous 14-game lead over New York at the All-Star Break, but the Red Sox had gone 25-24 and the Yankees had gone 35-14 before commencing a four-game series at Fenway Park on Sept. 14, 1978.
By the time the four-game set finished, the Yankees had accounted for 42 runs and 67 hits in just four days and swept the series. The Yankees won all four games by an average of over eight runs.
This would be famously known as the “Boston Massacre” but the best was yet to come. A week later, the Yankees took two of three from the Sox in the Bronx and eventually forced a one-game playoff.
The massacre was completed in that win-or-die face-off thanks to Bucky F**cking Dent’s go-ahead home run that sent the Yankees on their way toward an eventual repeat World Series championship.
Depending on who you ask, this collapse would become one of the greatest parts of the Yankees-Red Sox rivalry.
