Jake McCarthy homered, singled twice and drove in four runs, Ryan Feltner returned to the rotation with six shutout innings and the Colorado Rockies beat the San Francisco Giants 8-3 in Denver on Saturday night.

Kyle Karros also went deep, and TJ Rumfield and Willi Castro had two hits each for Colorado, which has won consecutive games for the first time since May 7-8.

Drew Gilbert homered among his two hits, and Jung Hoo Lee and Matt Chapman also had two hits for San Francisco, which has lost five in a row.

Feltner (2-1) was activated from the injured list (right ulnar nerve inflammation) to make his first start since April 23. He retired the first five batters he faced before Chapman's two-out double in the second, and he erased leadoff singles in the third and fifth innings with double-play grounders.

He left after scattering four hits and fanning two to earn his first win since April 6.

The Rockies, who used a five-run rally in the ninth inning to win 8-6 Friday night, built on that momentum in the first inning against Adrian Houser.

McCarthy led off with a walk and one out later, Goodman drew a base on balls to put runners on first and second. Castro followed with an RBI single, Ezequiel Tovar followed with a two-out single and Houser hit Sterlin Thompson with the bases loaded to make it 2-0.

McCarthy lined a two-run homer into the Colorado bullpen in the fourth inning, his third of the season, to double the Rockies' lead.

Houser (2-5) allowed four runs on eight hits in 3 2/3 innings. He struck out four and walked two.

The Rockies made it 5-0 on McCarthy's RBI single in the fifth and then padded the advantage in the seventh.

Karros led off the inning with a pinch-hit homer, his third of the season, Tyler Freeman reached on a bloop double and scored on McCarthy's single. McCarthy stole second and scored on Rumfield's single.

Gilbert spoiled Colorado's shutout bid with a two-run homer in the eighth, his third, and Chapman had a two-out RBI single in the ninth.
