Marco Scutaro had three hits, two RBI and two runs scored to lead the San Francisco Giants past the Colorado Rockies, 8-3, in the rubber match of a three-game series at Coors Field.

Joaquin Arias and Brandon Crawford added two RBI apiece for the NL West- leading Giants, who have won four of their last six.

Tim Lincecum (9-14) surrendered three runs on six hits and four walks with eight strikeouts over six innings to win his fifth straight road start.

"He has really elevated his game," San Francisco manager Bruce Bochy said. "He's gotten on track, which is huge for us. Some of the other guys have had some hiccups and he has picked us up."

Jeff Francis (5-5) was touched for five runs on seven hits over three innings to take the loss for Colorado, which lost for the eighth time in 10 games.

Wilin Rosario homered and knocked in two runs in defeat.

San Francisco wasted no time in getting on the board as Gregor Blanco led off the game with a triple and came home Scutaro's base hit to center field.

Scutaro then moved to third on a single by Buster Posey and Hunter Pence's fielder's choice before crossing the plate on an Arias base hit through the left side of the infield. Hector Sanchez's RBI single to left field and Crawford's two-run double to right field gave the Giants a 5-0 advantage.

"It's always tough when you're down by that many runs," Carlos Gonzalez said. "Obviously you want to have the game close so you feel much better at the plate."

Colorado answered with a run in bottom of the first when Gonzalez worked a two-out walk, advanced to second on a balk and scored on Rosario's single to left field.

After the Rockies failed to cut into their deficit further in the second inning by leaving the bases loaded, Rosario made it a 5-2 game in the third inning with a solo shot to left field.

But the Giants got a run back in the sixth inning when Crawford hit a leadoff double, moved to third on Lincecum's sacrifice bunt and raced home on Scutaro's two-out single.

Chris Nelson hit a one-out single and rounded the bases on Charlie Blackmon's pinch-hit double to right field in the bottom of the sixth to bring the Rockies back within 6-3, but they would get no closer and Pence knocked in Scutaro with a triple and came home on Arias' sacrifice fly in the ninth inning to account for the final margin.
