Bartolo Colon (6-6) got the win, surrendering five runs on nine hits over five innings. Ryan Cook allowed runners to reach first and second in the ninth before recording three straight outs to earn his first career save.
Tyler Colvin and Todd Helton both hit solo home runs for the Rockies, who lost their sixth straight game and fell to 0-7 in interleague play on the season.
Jeremy Guthrie (3-5) was charged with seven runs on eight hits over five inning in the setback.
