LOS ANGELES - Josh Rutledge began the season at Triple-A Colorado Springs before the Colorado Rockies recalled him less than three weeks ago. The little-used second baseman came up big in a key situation Sunday to help them win another series.
Rutledge hit a three-run homer to support Jorge De La Rosa's seven strong innings, and the Rockies beat the error-prone Los Angeles Dodgers 6-1 in the rubber game of the three-game set.
Colorado was leading 3-1 in the sixth when Rutledge drove Hyun-Jin Ryu's 89th and final pitch into the left-field pavilion. Rutledge's homer was the 16th of his career, and his first with more than one man on base since his grand slam Sept. 16, 2012, at San Diego. He came into the game with one RBI in 18 at-bats.
"Obviously, that changes the game there," manager Walt Weiss said.
Nolan Arenado had two hits and extended his career-best hitting streak to 17 games - the longest active string in the majors. The Gold Glove third baseman also robbed Scott Van Slyke of extra bases, making a diving stop across the foul line behind third base and throwing him out.
"I told him that was one of the top three plays I've ever seen him make. And that's saying something," Weiss said. "He's as good as I've seen."
The Rockies won their fourth straight series.
De La Rosa (2-3) allowed a run and four hits. The left-hander has beaten the Dodgers in three straight starts after going 0-8 with a 7.32 ERA in his 10 previous career starts against them.
"I just tried to attack the hitters," De La Rosa said. "I was just trying to make my pitches."
Justin Turner's throwing error in the second inning on De La Rosa's two-out single in the hole put runners at second and third. Ryu hit major league batting leader Charlie Blackmon with a pitch and gave up a two-run single by Brandon Barnes on an 0-2 count that put the Rockies ahead 2-1.
Three innings later, Blackmon scored the Rockies' third run after a double and an error, beating a throw by Turner after he tagged out Barnes.
