DENVER -- Instant replay saved the D-backs a run in Tuesday night's 4-2 win.
With one out in the bottom of the second the Rockies' Charlie Culberson doubled to the gap in right-center. Wilin Rosario tried to score all the way from first base and was ruled safe by home-plate umpire Jerry Layne. Arizona catcher Miguel Montero immediately began waving for manager Kirk Gibson to challenge the play.
"I didn't see it, but I just got the sign," Gibson said referring to bench coach Alan Trammell's thumbs up to challenge. "Miggy immediately said, 'I tagged him' and wanted me to come out and challenge it. I asked him and Jerry Layne said that he did not see a tag."
After a brief discussion with Montero and Layne, Gibson elected to use his challenge and the play was overturned, and instead of being the Rockies having a 1-0 lead, there were two outs and a runner on third.
"Big play to keep them off the board there," Gibson said. "That was a big play in the game."
"I don't know if it killed the momentum, maybe briefly," Rockies manager Walt Weiss said. "But it was early enough that we still had plenty of time to make it up."
D-backs starter Chase Anderson was able to pitch out of the inning without a run scoring. It was the 10th time Gibson has challenged a call this year and the fourth time it was overturned.
There was also a crew chief replay review in the bottom of the fourth with one out and Rosario at the plate in order to determine the count on the batter. The replay determined the count to be two strikes and two balls.
