MLB: Colorado 5, New York Mets 2

DENVER, Sept. 3 (UPI) -- Jason Giambi, in his first Colorado appearance, singled in the go-ahead runs in the eighth Wednesday to give the Rockies a 5-2 win over the New York Mets.

Colorado signed Giambi to a minor league contract after he was released by Oakland and the Rockies called him up this week.

With the score tied at 2-2 and the bases loaded with one out in the eighth, Giambi was called on to hit for Clint Barmes. He swung at the first pitch from Brian Stokes (1-4) and singled to center, driving in Troy Tulowitzki and Brad Hawpe.

Yorvit Torrealba followed with an RBI single and the Rockies held on for their second straight victory.

Colorado remained one game in front of San Francisco in the race for the National League wild-card berth.

Ubaldo Jimenez (13-10) went eight innings to get the victory, giving up two runs on five hits with four strikeouts. Franklin Morales worked a perfect ninth for his first major league save.

The Mets have lost nine of their last 11.
