DENVER — Nolan Arenado homered among his three hits and Chris Iannetta hit a go-ahead two-run double in the sixth inning to lead the Colorado Rockies over the San Francisco Giants 12-11 on Thursday.
Arenado reached base five times, starting with his 10th home run. Ian Desmond and Mark Reynolds also homered on a cold, sometimes wintry day at Coors Field.
The announced temperature at first pitch was 39 degrees and a steady snow fell in the first inning.
Colorado won despite two home runs and a career-best six RBIs by Giants first baseman Tyler Austin. He hit a two-run homer in the third inning and a three-run shot in the sixth off Bryan Shaw (2-0) to tie the game at eight.
Iannetta put Colorado back in front against reliever Tyler Beede (0-1) in the sixth, and pinch-hitter Daniel Murphy singled off Austin’s glove to put the Rockies ahead 11-8.
Both teams scored a run in the eighth and the Giants got two more in the ninth off Wade Davis before he struck out Stephen Volt for his sixth save.
The Rockies built a 7-0 lead in the second inning off starter Derek Holland. Arenado and Reynolds went back-to-back in the first and Desmond capped a four-run second with a two-run homer. The Giants rallied for five runs — three earned — off starter Kyle Freeland and tied it in the sixth.
Giants: LHP Drew Pomeranz was placed on the 10-day injured list with a lat strain. Pomeranz lasted just 1 2/3 innings in his previous outing. San Francisco recalled C Aramis Garcia and Beede in corresponding roster moves for Pomeranz and C Buster Posey.
Rockies: Manager Bud Black said LHP Jake McGee and RHP Chris Rusin were scheduled to pitch rehab assignments with Triple-A Albuquerque on Thursday. McGee (left knee sprain) was scheduled to start the game and Rusin (mid-back strain) was expected to come in later in the game.
POSEY OUT WITH CONCUSSION
The Giants placed Posey on the seven-day concussion list prior to Thursday’s game. Posey said he was hit with a foul ball Sunday against Cincinnati and felt the effects since despite playing in Tuesday’s 14-4 win over the Rockies.
“They are going to take extra time to find out how I am,” Posey said. “When they examined me (Wednesday) they felt I should have felt more normal after three days. When you are dealing with the brain, you’ve got to be cautious.”
Giants: RHP Dereck Rodriguez (3-4, 5.75) opens a three-game home series against the Cincinnati Reds on Friday night.
Rockies: RHP German Marquez (3-2, 3.46) makes his fifth home start of the season and ninth overall against the San Diego Padres on Friday night.
