When Chad Billingsley's start turned sour, the Los Angeles Dodgers' bullpen bailed him out. Manager Don Mattingly yanked Billingsley after he allowed four runs in the third inning to the Washington Nationals, and the relievers responded with 6 2/3 hitless innings. Tony Gwynn had a tiebreaking double in the ninth inning and the Dodgers beat the Nationals 7-4 in the first game of a doubleheader on Thursday.
