On April 27, 1982, in Jackson's first game back at Yankee Stadium with the Angels, he broke out of a terrible season-starting slump to hit a home run off former teammate Ron Guidry. The at-bat began with Yankee fans, angry at Steinbrenner for letting Jackson get away, starting the "Reg-GIE!" chant, and ended it with the fans chanting "Steinbrenner sucks!" By the time of Jackson's election to the Hall of Fame, Steinbrenner had begun to say that letting him go was the biggest mistake he had made as Yankee owner.
