Seth Smith hit a two-out, two-run single in the ninth inning to give the surging Colorado Rockies a 4-3 win over the Cincinnati Reds on Wednesday night.
Colorado won its sixth consecutive game and extended its NL wild-card lead to four over San Francisco, which lost 4-2 to San Diego.
Clint Barmes started the winning rally with a one-out double off All-Star closer Francisco Cordero (2-5). Pinch-hitters Jason Giambi and Ryan Spilborghs then walked before Cordero struck out Carlos Gonzalez to bring Smith to the plate.
Smith fouled off four balls before lining a base hit off second baseman Brandon Phillips to drive in Barmes and pinch-runner Jason Marquis.
Scott Rolen gave Cincinnati a 3-2 lead with a leadoff homer in the ninth.
