Mike Yastrzemski doubled, homered and scored twice to help the San Francisco Giants complete a four-game sweep of the Colorado Rockies with a 3-0 victory on Thursday afternoon in Denver.
Joc Pederson went 3-for-4 with an RBI and Luis Gonzalez and Jason Vosler each contributed two hits for the Giants, who improved to 11-5 against Colorado this season.
The Giants (73-77) used a string of relievers in the series finale.
Jharel Cotton (3-2) made his San Francisco debut and threw 2 2/3 innings of scoreless relief in the middle innings to earn the win. He allowed two hits, struck out one and didn't walk a batter.
Rockies starter Jose Urena (3-7) allowed two runs and seven hits in 5 2/3 innings. He struck out six and walked one.
Yonathan Daza and Michael Toglia had two hits each for Colorado (64-86), which had 10 hits.
The Giants took a 1-0 lead in the first inning when Yastrzemski doubled with one out and came home on a two-out single by Pederson.
Yastrzemski came up with one out in the sixth and blasted an 0-2 pitch deep over the fence in right for a 2-0 lead.
Yastrzemski has 10 home runs in 27 career games at Coors Field.
LaMonte Wade Jr. made it 3-0 with a two-out RBI single in the seventh.
John Brebbia started on the mound for San Francisco and allowed one hit in one inning.
The Rockies had the bases loaded and one out against Tyler Rogers in the second, but he induced an inning-ending double play, one of four by Colorado.
Jarlin Garcia followed with scoreless third and fourth innings for the Giants.
After giving up a leadoff double to Brian Serven in the fifth, Garcia got the next batter out before Cotton came out of the bullpen and retired the next two to keep Serven at second base.
Cotton got through the sixth and seventh innings unscathed thanks to inning-ending double plays. Colorado hit into another double play to end the eighth.
Cotton, 30, was designated for assignment by the Minnesota Twins last week and claimed by the Giants on Sunday.
