Trevor Story homered, Nolan Arenado picked up his major league lead-tying 112th RBI with a double as part of a four-run sixth and the Colorado Rockies beat San Francisco 9-6 on Tuesday night for their 10th straight win over the Giants at Coors Field.
The Rockies held off a late rally by the Giants to increase their lead to 2 1/2 games over Milwaukee for the second NL wild-card spot.
After spot starter Tyler Chatwood left after three innings, Colorado used eight relievers with Chris Rusin (4-0) earning the win. Greg Holland pitched a perfect ninth for his 37th save.
Denver native Ty Blach (8-12) surrendered five runs over 5 1/3 innings for the Giants. Blach made his major league debut at Coors Field on this day a season ago.
The Giants trailed 7-3 in the eighth, when Denard Span lined a two-out, two-run double. Joe Panik followed with an RBI single — his fourth hit of the game. Adam Ottavino was summoned into the game and struck out Buster Posey on a pitch way outside the zone to end the inning. The Giants left nine runners on base.
Arenado's 112 RBIs ties him with Miami's Giancarlo Stanton for most in the majors. The Rockies third baseman has led the league in the category in each of the last two seasons.
Pablo Sandoval went 0 for 4 with a walk and remains hitless in his last 37 at-bats. It's tied for the longest streak by a Giants player since Johnnie LeMaster went hitless in 37 at-bats in 1984.
Chatwood was limited to 61 pitches in his first start since Aug. 2. He's been working out of the bullpen.
