DENVER (AP) -- Jorge De La Rosa pitched six strong innings to win his sixth consecutive decision, Todd Helton homered and the Colorado Rockies snapped the Los Angeles Dodgers' six-game winning streak with a 7-5 victory on Wednesday night.
De La Rosa (16-6) allowed two runs and six hits in matching his career high for wins in a season and tying Washington's Jordan Zimmermann for most wins in the National League. De La Rosa went 16-9 in 2009 for the Rockies.
Colorado built an early lead off Edinson Volquez, who was making his first start for Los Angeles after being signed last week by the Dodgers following his release by San Diego.
Volquez (9-11) allowed four runs and six hits in four innings in falling to 0-5 in six starts against Colorado this season.
