Rockies 3, Giants 0: Tyler Chatwood pitched five shutout innings as visiting Colorado and its major-league worst pitching staff recorded its second shutout in four games.

Rookie Wilin Rosario doubled twice and caught two runners stealing, and Tyler Colvin had two hits and an RBI as the Rockies won for the third time in their last four contests, and for only the fourth time in their last 17 meetings with the Giants.

Colorado, which has a 5.37 ERA, dropped San Francisco into a first-place tie with the Los Angeles Dodgers in the National League West.

San Francisco outscored Colorado 35-13 in a three-game sweep at Coors Field last weekend, including an 8-3 victory Sunday when Tim Lincecum beat Chatwood. On Friday, Chatwood (2-2) allowed three hits, walked two and struck out two.

Lincecum on Friday recorded his third straight quality start for the first time this season, but fell to 6-12. He allowed three runs, six hits, walked two and struck out three in seven innings.

Colorado's Adam Ottavino walked two in two innings, Matt Belisle pitched a perfect eighth and Rafael Betancourt worked a 1-2-3 ninth for his 20th save in 21 chances to complete the three-hitter.

Dexter Fowler's two-out single scored D.J. LaMahieu with the game's first run in the third inning.

Colvin stroked a two-out single on an 0-2 pitch to right field to plate Rosario after his second double of the game came with one out in the fourth. Chris Nelson's sacrifice fly in the seventh inning scored Colvin, who led off with a single, stole second and moved to third on LaMahieu's sacrifice bunt.

San Francisco threatened with runners at first and third and one out in the fifth inning, but Lincecum struck out and Rosario threw out Brandon Crawford trying to steal second.

The Giants' Buster Posey had his 13-game hitting streak snapped when he flied out as a pinch hitter with two on and two out in the seventh inning.

Crawford went 2-for-3 and is batting .440 (11-for-25) against the Rockies this season.
