Chris Capuano threw seven shutout innings and drove in two runs to lead the Los Angeles Dodgers to a 5-1 win over the Chicago Cubs on Saturday.
Capuano (4-0) held Chicago to three hits and struck out seven, extending his scoreless innings streak to 18 2-3. His two-run double in the second gave him his first RBIs since Aug. 24, 2007.
Cubs starter Chris Volstad (0-4) fell to 0-9 over 17 starts dating to July 10. He allowed four hits and five runs over five innings, walking three and striking out one.
The first-place Dodgers avoided their first three-game losing streak of the season. It's just the second time since 1988 that Los Angeles has won at least 18 of its first 27 games.
Los Angeles started 19-8 in 2009, the last year the Dodgers won the NL West.
During Volstad's long winless streak, his Achilles' heel has been an inability to avoid big innings. The problem surfaced again on Saturday when his leadoff walk to Andre Ethier in the second led to a sacrifice fly.
Later that inning, Volstad left a pitch up to Capuano, who laced it into the gap in right-center for a two-run double.
Capuano, who was a capable hitting pitcher before missing two seasons with an elbow injury, had gone just 5 for 79 without an RBI since returning to the majors in 2010.
Capuano is off to his best start since winning his first five decisions in 2007. He's hoping this season turns out better after he lost his final 12 decisions that year. The lefty has won seven of his last nine starts against the Cubs, who barely threatened him on Saturday.
Chicago loaded the bases with one out in the first, but Capuano struck out Alfonso Soriano and Ian Stewart looking. The Cubs got just three base runners against Capuano over his last six innings and didn't get another runner past first base.
Matt Kemp went 0 for 3 but drove in a run with a sacrifice fly in the fifth.
Kemp's batting average dropped below .400 for the first time since April 10. The major-league home run leader hasn't gone deep in the Dodgers' last four games, his longest drought of the season.
Dee Gordon doubled home Matt Treanor in the fifth. Gordon also singled and stole his 12th base of the season.
Starlin Castro singled three times for the Cubs, but committed his eighth error, the most in the majors.
Bryan LaHair walked twice, extending his streak of reaching base to 23 straight games, but his career-best 10-game hitting streak was snapped.
