The Colorado Rockies head back on the road tonight for the first time since the season’s opening weekend. They open a six-game, two-city road trip in Milwaukee with the first of three games against the Brewers at Miller Park. The Rockies just concluded a nine-game homestand against divisional opponents on which they went 5-4, including wins in the final two games of the homestand over San Diego on Tuesday and Wednesday. They are 6-6 overall. The Brewers dropped to 6-7 overall after failing to complete a sweep of Los Angeles in a 4-3 home loss yesterday afternoon. Right-hander Jhoulys Chacin takes the mound for the Rockies searching for his first win of the season. Milwaukee counters with southpaw Shawn Marcum. ESPN Radio 1410 has the action, with pregame coverage at 6:30 and the first pitch at 7:10.
