The Dodgers are 19-4 in July, and have built a 3 1/2 -game lead over San Diego atop the NL West.
Los Angeles has not faltered away from Dodger Stadium since a 7-3 loss to Anaheim on July 2.
Bradley was 3-for-4 after entering the game mired in a 2-for-16 skid. Jose Hernandez also homered for the Dodgers, who had 12 hits in winning for the 18th time in their last 21 overall.
“We got the lead, we kept the lead and we got to the seventh inning,” Dodgers manager Jim Tracy said. “We’re pretty good from the seventh inning on when we have the lead.”
“We thought we were going to be able to come back and win the ballgame. We just weren’t able to do it,” Rockies manager Clint Hurdle said.
The Rockies will try to get back on track against Dodgers left-hander Odalis Perez.
Perez has failed to earn a decision in two starts since coming off the 15-day disabled list, but has allowed only two earned runs in 12 innings.
Perez stifled the Rockies on Thursday, holding Colorado to one run and four hits over seven innings in Los Angeles’ 4-2 win.
The 27-year-old left-hander is 5-3 with a 3.16 ERA in 12 career games, including 11 starts, against the Rockies. Perez is 3-1 in five starts at Coors Field despite a 5.90 ERA.
