On October 4, 1986, Righetti once again made history against the Red Sox when he saved both games of a doubleheader against them, finishing the season with 46 saves, and breaking the major league record shared by Dan Quisenberry and Bruce Sutter. The record would stand until Bobby Thigpen saved 57 games for the Chicago White Sox in 1990, which would also be Righetti's last season with the Yankees. Righetti retained the single-season record for left-handers until 1993, when Randy Myers saved 53 games for the Chicago Cubs; Righetti still owns the AL record for left-handers.
