Losing their challenge proved costly. In the sixth inning, Denard Span scored on a groundout by Bryce Harper and it appeared Harper beat the play for an infield single. In fact, Harper stood at first base expecting the play to be challenged. But manager Matt Williams couldn't do anything about it.
"We don't have a challenge left. We can't go out there for that challenge," Williams said. "We used it with Espy on the stolen base and felt confident that he was in there. But they ruled otherwise."
Harper felt the play at first was pretty close. When he looked at the video, it was clear to Harper that he was safe. It would have meant bases loaded, one out and Ryan Zimmerman coming to the plate.
"That would have changed the momentum of the game. That's pretty rough. It [stinks]," Harper said.
Zimmerman was then hit a by pitch, and Ian Desmond lined out to first baseman Anthony Rizzo to end the threat.
