The road trip struggles continued for the Colorado Rockies, who got off to a fast start against the Arizona Diamondbacks but blew a 4-1 lead in the opener of a three-game series.

Rockies move a half game ahead of the Giants in the wild-card race and have won five of their past six games, nine of their past 12 and 31 of 42 since June 3.

The Rockies, who blew a four-run lead Saturday, blew a three-run lead as they lost consecutive games for the first time since June 23-24 and saw their steak of four consecutive series wins at home end.
