Pittsburgh ? Umpire Tim Welke admitted Sunday he probably missed a call at first base that cost the Colorado Rockies the tying run in a loss to the Pittsburgh Pirates the day before.

Welke, the crew chief, called Colorado’s Jay Payton out at first base to complete a game-ending double play in Pittsburgh’s 1-0 victory Saturday.

There were runners at first and third and one out when Payton came to the plate.

Replays appeared to show Payton beat the throw from second baseman Abraham Nunez. Welke said Payton probably was safe.

“Now, I looked at the replays, and I know the replays aren’t very good, but I don’t get a second chance at it. It was a tough night sleeping last night,” said Welke, a major-league umpire for 21 years.

The Rockies argued that Payton was clearly safe. Colorado general manager Dan O’Dowd said Sunday he filed a complaint with Major League Baseball.
