I'd argue for Lenny Webster. May 31, 1991: Twins lose to fall to 23-25, 5th place, 5.5 games out of first; Junior Ortiz placed on DL after the game, Lenny Webster recalled June 1: Twins begin 15 game winning streak June 16: Ortiz activated, Webster sent down, Twins finish the day at 38-25, in first place June 17: Twins lose first game since May 31st Without that Webster magic, it's possible the Twins don't even win the division in 1991!
