Dan Haren tossed seven sharp innings to give the Dodgers four pitchers with 13 wins for the first time in 19 years, and Los Angeles beat the San Diego Padres 4-0 on Wednesday night. He joined Clayton Kershaw, Hyun-Jin Ryu and Zack Greinke as the first quartet with at least that many wins since Orel Hershiser, Fernando Valenzuela, Jerry Reuss and Bob Welch in 1985. Haren and J.P. Howell combined to retire nine consecutive San Diego batters before Kenley Jansen came on in the ninth to earn his 42nd save.
