The left-hander held Los Angeles to only two runs on two hits in seven innings, with three strikeouts and no walks in the win.
He'll get the chance to match that for the second time in a week when the Padres face the Dodgers and Aaron Harang in the series opener at Dodger Stadium on Friday.
Richard worked ahead in the count for much of that start, allowing only a two-run home run to Matt Kemp, with both runs unearned. The left-hander will try to get ahead of hitters again on Friday, understanding just how potent a lineup the Dodgers have.
"You know the middle of their order is extremely talented, so you don't want to fall behind those guys," said Richard.
That not only includes Kemp and Andre Ethier, who is 3-for-9 with five RBIs against lefties, but Juan Riviera, who already has eight hits and four RBIs this season.
"He's always been close to .300 and drives in runs for me," said manager Don Mattingly, whose Dodgers are 6-1 and off to their best start in 31 years. "And that's just what he's doing for us. He's never looked like a guy who would hit 30 homers. He drives in runs with singles. Juan doesn't change his approach with a guy on second base. He stays with the plan."
Harang will hope for that type of production out of the lineup after struggling in his debut against Richard. The right-hander surrendered four runs (three earned) on seven hits in 4 1/3 innings and took the loss against his former team.
"I felt I was pitching kind of tight," Harang said after the start. "I was tense or something. I put a lot of pressure on myself and just wasn't able to locate. You fall behind and got to throw strikes and that's when they get hits. I wasn't making the pitches, that's what it comes down to."
Padres: Quentin ready for live BP
In another positive step in the rehabilitation of his right knee, outfielder Carlos Quentin will take live batting practice this weekend.
Manager Bud Black said Thursday that Quentin will remain in San Diego for rehabilitation purposes while the team travels to Los Angeles.
Quentin had surgery on March 19 with the hope that he could play in four to six weeks, and so far, he's had no setbacks.
Dodgers: Team to speak at Robinson's high school
Dodgers past and present will visit Jackie Robinson's high school to talk about his legacy in advance of Jackie Robinson Day.
Current Dodgers players Dee Gordon and Tony Gwynn, along with Dodgers alumni Tommy Davis, Lou Johnson, Ken Landreaux and Derrel Thomas will speak about Robinson's impact on baseball and society at John Muir High School in Pasadena.
On Sunday, the Dodgers will celebrate the 65th anniversary of Robinson breaking the color barrier, when all uniformed personnel wear No. 42, which has been retired by baseball in honor of Robinson.
Pregame ceremonies will include the First African Methodist Episcopal Church Unity Choir performing the national anthem and the American Legion Jackie Robinson Post from South L.A. presenting the colors. Seven of the Dodgers' Team 42 scholars, who receive college scholarships through the Dodgers Dream Foundation and the Jackie Robinson Foundation, will be recognized on the field before the game and Dodgers alumni Don Newcombe and Davis will throw out ceremonial first pitches.
Padres right-hander Joe Wieland, who is considered one of the Padres' top pitching prospects, is set to make his Major League debut on Saturday at Dodger Stadium, Black confirmed before Thursday's game.
Hall of Fame broadcaster Vin Scully missed his third consecutive game Thursday night at Dodger Stadium with a bad cold. Charley Steiner and Steve Lyons called the game on PRIME TICKET, while Rick Monday and Kevin Kennedy were behind the microphone on AM 570 Fox Sports Los Angeles.
