MLB: Colorado 4, Cincinnati 3

DENVER, Sept. 9 (UPI) -- An infield single by Seth Smith drove in two runs with two away in the ninth Wednesday, rallying the Colorado Rockies to a 4-3 victory over Cincinnati.

The Reds took a 3-2 lead in the top of the ninth on a solo homer by Scott Rolen but let the game get away in the bottom of the inning on a grounder that eluded the grasp of second baseman Brandon Phillips.

Colorado's comeback gave the Rockies their sixth straight win and pushed their lead over San Francisco in the National League wild-card race to four games. The Giants lost earlier in the day to San Diego 4-2.

Francisco Cordero (2-5) came on in the ninth to protect the one-run lead and got Yorvit Torrealba on a fly ball to open the inning. Clint Barmes then doubled and pinch-hitter Jason Giambi walked.

After Jason Marquis was called on to run for Giambi, Ryan Spilborghs walked to load the bases.

Cordero struck out Carlos Gonzalez, leaving it up to Smith. He hit a grounder wide of second and Phillips made a diving stop but the ball got pinned under his body and by the time he collected it both Barmes and Marquis had scored to end the game.

Matt Daley (1-1) worked the final 1 1/3 innings and got the victory despite giving up the go-ahead homer to Rolen.
