SAN DIEGO (AP) -- When Clayton Richard was lost to a shoulder injury just two pitches into his start Friday night, Tim Stauffer and Tyson Ross helped extend the San Diego Padres' remarkable run by shutting down the Dodgers for seven innings.
Chris Denorfia and Chase Headley each had two RBIs as the Padres roughed up Clayton Kershaw and four relievers shut down the Dodgers in a 5-2 victory over Los Angeles on Friday night.
''Tim and Tyson were the players of the game,'' Padres manager Buddy Black said. ''What they did on short notice was really impressive.''
San Diego has five starting position players out with injuries and now Richard's headed to the disabled list with shoulder inflammation, but the Padres keep on winning.
The surging Padres are an NL-best 13-7 in June. San Diego has won eight straight at Petco Park and nine of their last 11 overall.
Stauffer (1-0) relieved Richard and earned his first win since Sept. 16, 2011, by allowing one run in four innings. Ross followed that with three shutout innings.
The Dodgers have lost nine of 12.
Kershaw (5-5) allowed four runs on seven hits in six innings. He allowed four earned runs in a game this season just once prior to Friday. The Dodgers ace has struggled against San Diego, going 0-3 with a 4.67 ERA in three starts this year.
''They are a team that battles him pretty good,'' Dodgers manager Don Mattingly said. ''It certainly helps that they've seen him a lot. They're a club that makes him pitch and extends at bats. They've been tough on him, and tonight they scratched out enough runs to win.''
Black said Richard would head to the disabled list with inflammation in the left arcomioclavicular joint, located at the top of the shoulder near the collarbone, and pain in his neck and upper chest.
''It was rough, something I hoped wouldn't happen,'' Richard said. ''I had some discomfort this week leading up to (the start), but I thought I'd be able to get through. Unfortunately, once I got going I knew things weren't right.
''Once we get it isolated and figure out exactly what's going on, we'll be able to get it calmed down and go from there,'' he said.
Stauffer allowed a run in the top of the first, but Denorfia homered off Kershaw in the bottom half to tie it 1-all. Then the Padres added three more runs in the third.
Logan Forsythe doubled and Denorfia walked before Chase Headley hit a triple. Kyle Blanks drove him home in the next at-bat for a 4-1 lead.
Hanley Ramirez's RBI double off Dale Thayer in the eighth made it 5-2.
Dodgers rookie phenom Yasiel Puig went 2 for 4 against the Padres, which raised his average to .455 and marked his 11th multihit game in 17 major league games.
NOTES: Dodgers CF Matt Kemp will start a three-game minor league rehab assignment on Saturday with Triple-A Albuquerque. He'll play designated hitter in the first game and move to the outfield in the final two. Kemp has been sidelined since May 30 with a right hamstring strain. If he avoids a setback, Kemp should be back in the big leagues next week. OF Scott Van Slyke (shoulder) will also start a rehab assignment with Albuquerque on Saturday. . OF Andre Either did not start Friday's game with minor knee swelling, but he pinch hit in the seventh. . LHP Chris Capuano threw a light bullpen Friday, after earning a win against the New York Yankees on Wednesday. Capuano felt great after his first start since straining a triceps muscle on May 29. . Padres LF Carlos Quentin took on-field batting practice for the first time since injuring his shoulder a week ago. He hurt himself swinging a bat on Jun 14 and hasn't played since. . Padres 2B Jedd Gyorko (groin) ran and hit for a second straight day. He's scheduled to start a minor league rehab assignment soon. It'll likely be a three-game stint with Class-A Lake Elsinore. . 1B Yonder Alonso (broken hand) will be examined on Monday by Dr. Lorenzo Pacelli. If that exam goes well, Alonso will resume baseball activities shortly after.
