In another incident typifying the Yankees-Red Sox rivalry, Fisk was involved in an altercation with Lou Piniella during a May 20, 1976, game at Yankee Stadium. In the sixth inning of this game, Piniella barreled into Fisk trying to score on an Otto Vélez single. Fisk and Piniella shoved each other at home plate, triggering another bench-clearing brawl. After order appeared to be restored, Red Sox pitcher Bill Lee and Yankees third baseman Graig Nettles began exchanging words and punches, igniting the brawl anew. Lee suffered a separated left shoulder in the altercation and missed much of the season and was never quite the same again.
