Rockies pitcher Alex White homered and Colorado finally solved a struggling Ryan Vogelsong, beating the San Francisco Giants 6-5 Monday night to snap a five-game losing streak.
Buster Posey and Hunter Pence went deep for the Giants, who lost for only the second time in 10 road games. San Francisco's lead in the NL West was trimmed to five games over the idle Los Angeles Dodgers.
Trailing 6-2, the Giants got a two-run homer from Posey in the seventh inning off reliever Rex Brothers and pulled within one in the eighth. Brandon Crawford drew a one-out walk from Matt Belisle, pinch-hitter Aubrey Huff singled and Angel Pagan followed with an RBI double, his third hit of the game.
Belisle got out of the jam by retiring Marco Scutaro and Pablo Sandoval.
Guillermo Moscoso (2-1) picked up the victory by working two innings, allowing one run on three hits. Rafael Betancourt pitched a 1-2-3 ninth for his 28th save in 33 chances.
Colorado manager Jim Tracy was ejected in the bottom of the seventh by second base umpire Angel Campos after a heated argument over an inning-ending double play. Campos ruled that Scutaro tagged Josh Rutledge before throwing to first to get Carlos Gonzalez. Tracy, ejected for the third time this season, argued that Scutaro missed the tag.
The Rockies also lost catcher Ramon Hernandez to a left hamstring strain sustained while running out a double in the fourth. He was replaced by pinch-runner Wilin Rosario, who advanced when Chris Nelson reached on first baseman Brandon Belt's fielding error and came home on Charlie Blackmon's double-play grounder.
Vogelsong (12-8) allowed four runs and six hits over five innings in losing for the first time in seven career starts against the Rockies while with the Giants. The outing extended a tough stretch over his last six starts since Aug. 13 in which he has gone 2-3, allowing 28 runs on 43 hits in 26 1-3 innings for an ERA of 9.57.
The right-hander entered 5-0 with a 1.80 ERA in six previous starts against the Rockies for the Giants, who had won all six games. But he was in trouble from the outset this time, allowing successive doubles to Tyler Colvin and Rutledge, the first two batters he faced. One out later, Jordan Pacheco hit an RBI single to put the Rockies up 2-0.
White hit his first career homer in the second, offsetting a drive he allowed in the top of the inning to Pence for the Giants' first run. White was lifted after allowing one run on six hits in four innings after throwing 76 pitches, roughly the limit for starting pitchers in the Rockies' unorthodox four-man rotation.
A two-out error by Sandoval on Rosario's grounder to third opened the door to a pair of runs by the Rockies in the sixth. Nelson followed with a run-scoring triple and Blackmon added an RBI single to build a four-run lead.
NOTES: LHP Josh Outman was recalled from Double-A Tulsa before the game by the Rockies. ... Six of the 16 homers allowed by Vogelsong have come in his last four starts. ... White's homer was the first by a Rockies pitcher since May 7 when Drew Pomeranz went deep against San Diego's Edinson Volquez.
