43. The Boston Massacre
Date: 09/07/1978 to 09/10/1978
If there's one name that is associated with the beginning of the modern Yankees-Red Sox rivalry, it's Bucky Dent. But without the Boston Massacre, there's no Bucky Dent. In two months the Yankees had trimmed a 14.5 game Red Sox lead to four entering a four-game set in Fenway. When the Bombers left town, the teams were even and four weeks later Dent had a new middle name.
