On April 26, 1969, tied 4-4 with two outs in the top of the ninth at Connie Mack Stadium in Philadelphia, the Cardinals exploded for 6 runs on their way to a 10-4 victory over the Phillies. The huge inning was sparked by a solo shot by Lou Brock. The long ball was followed by singles off the bats of Curt Flood and Bill White, then the Moon Man Mike Shannon added to the lead with an RBI single that brought Flood trotting into score the sixth Cardinals run of the contest. The hit parade was not done just yet. Vada Pinson singled to load the bases, then Tim McCarver clear'em all with a Grand Slam that gave the Cardinals the commanding 10-4 lead. The Birds were down 3-1 earlier in the contest before Shannon connected on a three run shot in the eighth that gave them 4-3 edge. The lead was short lived though, because in the bottom of the eighth Richie Allen parked one over the wall to tie it. Allen's homer simply set up for an exciting finish by the Cards who called in Joe Hoerner after the offensive explosion to close out the game. Hoerner made quick work of the Phillies with a 1-2-3 inning that added a Big Red W to the win column.
