SAN FRANCISCO (AP) - Tim Lincecum pitched San Francisco one win closer to an NL West crown, and the Giants lowered their magic number to clinch the division to seven with a 6-3 victory over the Colorado Rockies on Tuesday night.
Lincecum (10-14) struck out six and walked two in 6 1-3 scoreless innings on a day the second-place Los Angeles Dodgers were postponed by rain in Washington.
Marco Scutaro had three singles, drove in a run and scored twice and Xavier Nady had two RBI singles for the Giants (85-63), who moved a season-high 22 games over .500. Pablo Sandoval added two hits, including a double, and Hunter Pence added a sacrifice fly.
Wilin Rosario hit a two-run homer off Santiago Casilla in the eighth inning, matching the Rockies' rookie record of 25 set by Todd Helton in 1998.
