There was a time last month when the Los Angeles Dodgers' starting staff was able to thrive despite Dan Haren's struggles. The right-hander will try for a fourth win in five starts Friday night as the Dodgers open a three-game series with the San Diego Padres, baseball's best home team since the end of June. Los Angeles (76-58) is operating with starters Josh Beckett and Hyun-Jin Ryu on the disabled list while Zack Greinke pitches through elbow soreness. "I have to be able to step up," Haren told MLB's official website.
