DENVER -- The Colorado Rockies fell behind three times Friday, but they came back to beat the San Francisco Giants 6-4.

It was the Rockies' third straight win, and gave them a 3-2 record on their homestand with two games remaining.

It also ended San Francisco's three-game winning streak, and was Colorado's fourth straight victory this season against the Giants. The Rockies swept a three-game series in San Francisco on April 13-15.

Eddie Butler (3-1) allowed four runs in six innings but ended up the winning pitcher when the Rockies chased Giants starter Chris Heston (2-2) during their three-run sixth that put them back on top 6-4.

Right fielder Carlos Gonzalez broke an 0-for-16 slide in the sixth with a leadoff double, an opposite-field poke into the left-field corner. Second baseman DJ LeMahieu followed by grounding a double inside first base.

With one out, pinch hitter Rafael Ynoa doubled, the second straight time he has done that as a pinch hitter. That drove in two runs and was the 11th hit allowed by Heston, ending his evening. Left-hander Javier Lopez came on and gave up a two-out single to right fielder Corey Dickerson, an opposite-field flare to left that scored Ynoa.

The Rockies' 15-hit attack included eight extra-base hits -- seven doubles and a solo homer in the third by center fielder Charlie Blackmon. LeMahieu had three hits, including two doubles, and two RBIs

After Christian Friedrich and Brooks Brown pitched the seventh, Boone Logan came on in the eighth. He gave up a leadoff single and a walk but got third baseman Casey McGehee to ground into a double play. Logan then threw a called third strike past shortstop Brandon Crawford, who disagreed with home plate umpire John Tumpane. Giants manager Bruce Bochy came out to argue and was ejected by Tumpane.

The Rockies also trailed 2-0 in the second and 3-2 in the third but tied the Giants in each of those innings.

Rockies closer Adam Ottavino, who was unavailable Thursday due to slight tightness in his lower right triceps muscle, pitched the ninth and earned his third save while extending his scoreless streak this season to 9 1/3 innings.

The Giants took a 4-3 lead in the fifth on a two-out double by first baseman Brandon Belt. The hit scored second baseman Joe Panik, who led off with a double.

Thanks to third baseman Nolan Arenado, Rockies starter Eddie Butler avoided a big inning in the fourth. After giving up two singles to start the inning, McGehee hit a hard grounder that Arenado backhanded near the third-base line. He then ran about 15 feet to the base to force Brandon Belt and fired to first just in time to get McGehee and complete a spectacular double play.

Giants left fielder Gregor Blanco led off the third with a double and scored on center fielder Angel Pagan's one-out single, putting the Giants ahead 3-2. But Pagan was doubled off first base after Blackmon made a running catch in right-center.

Blackmon then led off the third with his second homer of the season to tie the score at 3-3.

Right fielder Justin Maxwell had given the Giants a 2-0 lead in the second when he followed a leadoff walk to Belt with his second homer of the season.

The lead didn't last long, however, as first baseman Justin Morneau and catcher Nick Hundley hit back-to-back doubles in the Rockies' half of the inning. LeMahieu singled home the second run.
