May 21, 1967. It only counted as one game but it took the 1967 Phillies 18 innings to bring down the Reds. The Phillies scored in the first inning when Johnny Briggs drove in Tony Gonzalez with a sacrifice fly. The Reds tied it in the top of the ninth when Tony Perez singled in Tommy Harper.
It wasn't until the bottom of the 18th that Don Locke drove in Dick Allen from second to end the 4 hour 38 minute marathon. The most amazing thing about this game is the fact Phils Manager Gene Mauch only used two pitchers for all 18 innings. Starter Chris Short went 12 innings and Dick Hall threw the final six innings for the win.
