July 4th, 1976
On this day in 1976, after hitting an apparent grand slam in the top of the second inning, Tim McCarver is credited with only a three-run single when he passes teammate Garry Maddox on the base paths in the Phillies' 10-5 victory over the Pirates at Three Rivers Stadium. The other base runners are allowed to score on the Philadelphia catcher's 'grand slam single' because only the player who passes his teammate is called out and there were less than two outs.
