Philadelphia manager Ryne Sandberg's successful appeal of a fifth-inning play at first base resulted in a replay review reverting the Bucs' lead from 3-0 to 2-0.
Seconds after Andrew McCutchen had given the Bucs a 2-0 lead with a bases-loaded single with two outs in the fifth inning, Starling Marte appeared to add to it with an infield hit.
With Josh Harrison on third, Marte sent a dribbler to third baseman Cesar Hernandez, whose throw to first was ruled tardy by first-base umpire Dale Scott as Harrison scored.
Pirates manager Clint Hurdle immediately braced for Sandberg's challenge.
