DENVER (AP) -- Nolan Arenado had four hits and four RBIs, leading Chad Bettis and the Colorado Rockies to an 11-2 victory over the San Francisco Giants on Sunday.
Troy Tulowitzki and Nick Hundley each drove in two runs as Rockies earned a split of the rain-soaked, four-game series.
Bettis (1-0) was nearly unhittable until the ninth inning. Nori Aoki singled on the first pitch of the game, and San Francisco's next hit was Matt Duffy's leadoff single in the eighth.
Bettis was charged with two runs and six hits in a career-long 8 1/3 innings. He struck out a career-high seven and walked two.
Aoki led off the ninth with a double and scored on Joe Panik's single to left. Buster Posey's one-out single extended his hitting streak to 16 games and Brandon Belt followed with an RBI double to chase Bettis. Brooks Brown got the last two outs.
The start of the game was delayed 2 hours, 10 minutes while a thunderstorm moved through the area. All four games in the series were delayed by rain, including both ends of Saturday's doubleheader.
The Rockies have dealt with weather delays at Coors Field throughout the spring. Saturday's nightcap was a makeup of an April 26th rainout, and four other games were either postponed or shortened due to rain.
Colorado's offense had a nice day once the skies cleared.
Arenado tripled and scored in the second. He started Colorado's eight-run fourth with a single and capped it with a three-run drive on the first pitch he saw from reliever Jean Machi.
Hundley and Daniel Descalso had RBI singles and Tulowitzki had a two-run single ahead of Arenado's team-best eighth homer.
Arenado singled up the middle in the sixth to make it 10-0. It was his fifth career four-hit game. He flied out in his last at-bat.
Giants starter Tim Hudson (2-4) remained winless in Colorado after allowing eight runs and six hits in 3 2/3 innings. Hudson is 0-3 in 10 starts at Coors Field. It is the only NL park he has not recorded a win.
San Francisco pitchers came to Denver having not allowed a run in 28 innings and extended it to 34 innings in Friday's opener. The staff allowed 32 runs in the last 28 innings of the weekend series.
Giants 3B Casey McGehee was designated for assignment before the game. McGehee won the NL Comeback Player of the Year award with Miami last season but has struggled this year. McGehee has 10 days to be traded, released or accept an assignment to Triple-A.
Giants: San Francisco will carry 13 pitchers into the second leg of the road trip because of the heavy workload due to the number of games the team has played. The Giants recalled RHP Hunter Strickland to help a fatigued bullpen. "I'm a little concerned how much we've been using these guys," manager Bruce Bochy said. "We've got to get that pen back in order. I knew it would be a test for us and the bullpen getting through this stretch of games."
Rockies: RHP Jordan Lyles has been diagnosed with a sprained toe on his left foot. He suffered the injury in the first game of Saturday's doubleheader. Manager Walt Weiss said he isn't sure if Lyles can make his next start, which would be Friday in Philadelphia.
Giants: RHP Tim Lincecum (4-2, 2.08 ERA) gets the ball in the opener of a three-game series in Milwaukee on Monday. Lincecum is 4-3 with a 4.16 ERA in 11 career starts against the Brewers.
Rockies: RHP Eddie Butler (2-5, 4.38) opens a three-game series in Cincinnati. Butler has pitched a combined 5 2/3 innings in his last two starts and has seen his ERA jump from 3.73 to 4.38.
