A home run by hot-hitting Buster Posey backed a strong start by Jake Peavy, as San Francisco picked up a game in the National League West race by edging Arizona 2-1 Tuesday at Chase Field in Phoenix.

The Giants’ victory, combined with Colorado’s 10-4 win over Los Angeles, left San Francisco three games behind the Dodgers with 11 games remaining. In the process, the Giants snapped a three-game losing streak.

Peavy (6-4) gave up one run on five hits, struck out four and issued one walk in 7 2/3 innings. Acquired from Boston in July before the non-waiver trade deadline, Peavy is 3-0 in his last five starts.

Diamondbacks starter Josh Collmenter (10-8) allowed two runs on seven hits in his eight innings of work.

Posey put the Giants on the board with a solo homer in the fourth inning, his 21st of the season. In his career, Posey is 11 for 20 (.611) with three home runs against Collmenter.

Arizona tied the game at 1-1 when Chris Owings tripled and scored on a single by A.J. Pollock.

The Giants went ahead to stay in the seventh on a sacrifice fly by Brandon Crawford that scored Hunter Pence, who singled and moved to third on a base hit by Travis Ishikawa.

The Diamondbacks tried to rally with two out in the bottom of the eighth with runners on first and second, but reliever Sergio Romo got Pollock to fly out, ending the inning. Santiago Casilla picked up his 16th save by hurling a perfect ninth inning.

Elsewhere for San Francisco, Pablo Sandoval had two hits, and Crawford had a bunt single and double.
