Joe Beimel, Jonathan Broxton and Takashi Saito allowed Arizona nothing and struck out three over the final 3.1 innings.
He was supported by a 15-hit attack that featured home runs by Tony Abreu (#2) and James Loney (#13).
Pierre had four hits and a walk, Loney added three, Martin two and every starting position player collected at least one safety.
The charging Rockies, who won their eighth straight, are only four behind the Diamondbacks and 1 1/2 behind San Diego in the wild card race.
Billingsley also profited from some spectacular fielding. Andy LaRoche saved a two-run double in the first and made two other highlight stops. Abreu ranged well behind second, threw almost backhand and Loney gobbled up the ball well down the foul line for the out. Kemp also made a fine running catch in foul ground in the sixth.
The Dodgers got four hits in the first inning and scored only a single run, a home run by Tony Abreu. Juan Pierre singled and was nailed stealing, Kemp and Loney singled but were left on.
Arizona got three singles in the first and tied the game.
James Loney and Russ Martin opened the fourth singles, and they both scored on a sac fly by Andre Ethier and a single by Andy LaRoche.
They added another pair in the fifth when Pierre drew a rare walk and Loney's third hit of the game curled around the right field foul pole for his 13th home run and a 5-1 lead.
Billingsley started to struggle in the sixth, allowing a single and a pair of walks, and was relieved by Joe Beimel, who set a new record for lefthanders with his 81st appearance. He ended the sixth with a ground ball to second.
LaRoche walked in the eighth and when no one payed any attention to him, stole second. He scored when Chin=Ling Hu singled to right. Pierre beat out an infield hit and when the DBacks shortstop threw the ball away, Hu scored to make it 7-1.
Broxton set the Snakes down 1-2-3 in the bottom of the eighth. Then Takashi Saito worked around a hit batsman to pitch a scoreless ninth.
The Dodgers have Monday off, then face the Rockies, who have won eight straight, and then finish with the Giants.

Dodger Blue Notes-- Joe Beimel's 81st moved him past Tom Martin (80 - 2003) for the most appearances by a lefty in Dodger history. Beimel and Jonathan Broxton are now tied for fourth place on the franchise's single season games pitched list, six behind Paul Quantrill (86, 2002). Broxton (T-2nd), Beimel (T-2nd) and Scott Proctor (79, T-5th) all rank in the top five for games pitched this season in the Major Leagues. ...James Loney collected two more hits last night and is hitting .434 (23-for-53) over his last 13 games while driving in 20 runs over his last 16 contests. Loney is hitting .395 (34-for-86) with seven home runs, seven doubles and 25 RBI in the month of September. His 25 RBI this month are second in the NL, behind Matt Holliday (26). ...Matt Kemp celebrated his 23rd birthday and collected his first birthday hit after not playing on his B-day last year. ...For your history lesson today, on this date in 1962, Maury Wills swiped his 97th base, to break Ty Cobb's single-season Major League record. And one year ago today, Brad Penny struck out four Diamondbacks in one inning at Dodger Stadium, tying the Major League record. Penny fanned Chad Tracy to lead off the second inning, but he reached on a passed ball by Russell Martin. The big right-hander would go on to strike out Stephen Drew, Miguel Batista and Eric Byrnes in the frame.
