The blasts returned to Coors Field on Friday night -- long before the fireworks.

In a throwback to the pre-humidor days, Colorado beat the Florida Marlins 18-17 after trailing by nine runs in the biggest comeback in Rockies history. Chris Iannetta singled home the winning run off Kevin Gregg in the ninth inning.

Garrett Atkins, who had a career-best five hits, drove in the tying run off Gregg (6-4), who blew his second save in 24 hours. After Hanley Ramirez's error on a potential double-play groundball loaded the bases, Iannetta singled to left through a drawn-in infield.

Colorado scored in every inning but the eighth, yet trailed until Atkins' tying single in the ninth. Taylor Buchholz (3-2) threw one inning for the win, Colorado's fourth straight.
