SAN DIEGO (AP) -- Wilin Rosario had a career high four hits and drove in three runs and Jhoulys Chacin beat San Diego for the second time this season, leading the Colorado Rockies over the Padres 9-5 Saturday night.
Rosario broke a 1-1 tie in the second with his fourth home run of the season, a two-run drive off Edison Volquez (0-3). Rosario made it 5-1 with an RBI single in the third, singled off Thad Weber leading off the fifth and singled off Joe Thatcher in the ninth.
Chacin (2-0) allowed two runs and four hits in five innings, his ERA rising from 1.35 to 1.96. He threw 83 pitches, extending the Rockies' streak of consecutive games without a 100-pitch start to 113. Colorado is 5-0 against the Padres this season.
Volquez gave up seven runs - six earned - six hits and three walks in 3 1-3 innings, leaving him with an 11.68 ERA. San Diego's fourth straight loss dropped the Padres to 2-9.
San Diego's Carlos Quentin, on the active roster while the players' union appeals his eight-game suspension stemming from Thursday's brawl with Los Angeles Dodgers pitcher Zack Greinke, popped out to the catcher as a pinch-hitter in the eighth with runners on second and third and two outs.
Michael Cuddyer hit a two-run homer in the fourth off Weber, giving the Rockies a major league-leading 15 on the road this season. Carlos Gonzalez had three hits and a walk, and Troy Tulowitzki had two hits and two RBIs.
Todd Helton hit an RBI double in the third, tying Ivan Rodriguez for 20th on the career list with 572 doubles.
San Diego's Everth Cabrera tied his career high with four hits, including a triple and home run in the seventh off Edgmer Escalona. Will Venable homered off Escalona later in the inning.
With the chance to become the first Padres player to hit for the cycle, Cabrera singled in the ninth.
NOTES: Reid Brignac was in the starting lineup at third base for the Rockies as Chris Nelson was given the night off by manager Walt Weiss. Weiss said Yorvit Torrealba will be the starting catcher Sunday when Jorge De La Rosa starts. Clayton Richard pitches for the Padres.
