KANSAS CITY, Mo. -

Much-maligned Mike Moustakas hit a three-run double in the second inning, and Jason Vargas and the Kansas City bullpen made the meager offense work in a 3-2 victory Wednesday over the Colorado Rockies for a two-game sweep.          

Vargas (4-1) did not allow a hit until the fourth inning and did not allow a run until Drew Stubbs belted a two-run homer to left in the seventh that made things interesting.        

Louis Coleman got the Royals out of the inning without any more damage, and Kelvin Herrera worked a perfect eighth before Greg Holland survived a shaky ninth for his 10th save.         

Jhoulys Chacin (1-1) allowed the three runs that Moustakas drove in but otherwise pitched well for Colorado. He allowed seven hits and a walk over six gritty innings.
