Adrian Beltré's 48th grand slam home run tied him with Mike Schmidt of the 1980 Philadelphia Phillies for the most homers by a third baseman in Major League history. He is one away from Shawn Green's club record of 49.
Green, despite striking out three times, scorched a RBI single in the eighth and pinch-hitter Robin Ventura's grounder allowed Bradley to score the tying run in the eighth.
Werth got things started for the Dodgers in the ninth with a one-out single to left. Steve Finley followed with a single to left-center, sending Werth to third, before the Rockies walked Beltré to bring up Bradley.
Bradley danced around first, then raised his right hand after his teammates mobbed him in celebration, holding aloft four fingers. The crowd of 36,958 yelled in approval at the sight of Bradley's fingers, knowing any combination of Dodgers victories or San Francisco Giants losses totaling four will give the Dodgers the National League West title.
After Beltré drove in his 121st run to erase a 2-0 Colorado lead, Jackson gave up two runs in the third and three in fourth before leaving the premises.
He almost allowed another homer before the umpire ruled that a fan had reached over the left-field fence to touch the ball. However, The Rockies rocked Jackson and took a 7-5 lead.
Colorado retired 16 of the next 17 Dodgers and things looked dark indeed before the late-inning heroics. Yhency Brazoban (4-1), who threw a grand slam in San Francisco, retired the only batter he faced in the ninth to earn the win.
Reliever Scott Stewart replaced Jackson and gave up one run on three hits in two-thirds of an inning. Wilson Alvarez then retired the Rockies in order in the fifth and sixth innings and Duaner Sanchez did the same in the seventh and eighth. Giovanni Carrara, Mike Venafro and Yhency Brazoban each pitched one-third of an inning in the top of the ninth.
The Dodgers won in their last at-bat for the 23rd time this year.
