Riding a Rocky Mountain High like none other, Colorado is heading to its first World Series.

With their 21st win in 22 games, the relentless Rockies beat the rattled Diamondbacks 6-4 in Game 4 Monday night to sweep the NL championship series at a chilly Coors Field.

Series MVP Matt Holliday's three-run, 452-foot shot into the pine-filled rock pile in center field capped a six-run outburst in the fourth inning, and the wild-card Rockies -- a team that debuted in 1993 -- were on their way.
