PHILADELPHIA (AP) -- Tyson Ross came into Citizens Bank Park riding a hot streak. It took less than one inning for that to come to a screeching halt.
Carlos Ruiz had three hits and three RBIs and rookie Cesar Hernandez reached base four times, scored twice and drove in two runs as the Philadelphia Phillies rode a six-run first inning to a 10-5 victory over the San Diego Padres on Thursday night.
Ross (3-8), who had a 2.16 ERA in nine starts since rejoining the rotation on July 23, gave up five hits and six earned runs with two walks and two strikeouts in just two-thirds of an inning.
"It was not his night at all," Padres manager Bud Black said. "The first inning had a check-swing chopper, then he fell behind and started throwing his first ball over the plate. Their hitters just squared up and he couldn't get the one pitch to stop the damage."
Roy Halladay was in line for the win for the Phillies but couldn't get through the fifth inning after walking four straight batters and committing a throwing error. In his fourth start since coming off the disabled list on Aug. 25, Halladay gave up five runs -- four earned -- and four hits, striking out six and walking a season-high five in 4 2-3 innings.
After two hits to start the first, Utley delivered an RBI single and Ruiz drove in two more with a double in the left-center field gap before Ross even recorded an out. The hard-throwing Padres right-hander was pulled from the game with two outs in the first after Halladay drew a based-loaded walk.
"He couldn't find the strike to get Halladay and walked in a run," Black said. "That was critical. He had him 1-2."
Following Ross' early exit, San Diego reliever Anthony Bass gave up a two-run double to Hernandez, who had led off the first with a single. The inning ended when Halladay was easily thrown out at home trying to score from first on Hernandez's double.
The Phillies added a run in the third, two in the fifth and one in the seventh, and five relievers held San Diego hitless over the final four innings to lead Philadelphia to its fifth victory in their last six games.
Justin De Fratus (3-3) was credited with the win after getting out of the fifth-inning jam.
Utley added two RBIs and Freddy Galvis and Kevin Frandsen collected two hits apiece for the Phillies, who took the rubber game of the three-game series in front of 29,986 rain-soaked fans watching two teams already eliminated from playoff contention.
"It was one of those games out of 162 that you just want to turn the page," Black said. "The Phillies just beat us."
After a 55-minute rain delay that pushed back the start of the game, Padres outfielder Will Venable belted a leadoff home run to right field on the third pitch he saw from Halladay. The homer was the 22nd of the season for Venable and the ninth leadoff homer of his career, a Padres record.
Tommy Medica, who homered in his major league debut on Wednesday, led San Diego with two hits, including the infield hit that drove in a run and knocked Halladay out of the game in the fifth.
But the Padres were fighting an uphill battle all night because of the poor outing from Ross.
"Adam Wainwright gave up nine runs against Cincinnati, so it can happen to the best of them," Black said. "Wainwright is a good pitcher. So is Tyson Ross."
NOTES: The Phillies have not lost a series to the Padres since Aug. 24-26, 2007. . With his first-inning walk, Halladay picked up his first RBI since Sept. 11, 2012. . The Phillies matched their season-high for hits in an inning with six in the first. It was the fifth time this season they accomplished the feat. . The Padres announced that Trevor Hoffman has been appointed to the role of upper level pitching coordinator & special assistant to the general manager. The former star closer spent the last three seasons as a special assistant to the president & CEO.
