Buster Posey joined a very exclusive club with his first home run in a month for the San Francisco Giants.

Posey hit his 17th home run of the season in the top of the fourth inning, giving him 100 for his career. Matt Duffy continues to have a great rookie year, as he hit a two-run triple in a five-run fifth inning and the Giants salvaged a split in the four-game series with a 7-4 victory over the Colorado Rockies at Coors Field.

Madison Bumgarner picked up his 17th win of the season, as he went six innings, allowing four runs on nine runs, walking one and striking out three.

With the victory, the Giants also picked back-to-back victories on the road for the first time in a month.

After the Duffy triple in the fifth, Posey was intentionally walked. Marlon Byrd, who went 4-for-5 on the afternoon greeted reliever Brett Brown with a single that scored Duffy.

Brandon Belt was walked by reliever Rex Brothers and then Brandon Crawford broke the game wide open with a double of his own.

The Rockies cut the down to 7-4 in the bottom of the fifth, as Cristhan Adames hit a two-run single; however Bumgarner regrouped to get Nolan Arenado to ground into a double play and then Carlos Gonzalez lined out to first end the threat.

Santiago Casilla picked up his 32nd save in 37 opportunities, as he pitched a perfect ninth inning.
