The Colorado Rockies still have a shot at the postseason heading into the final week of the regular season after a three-game sweep of Arizona. Kyle Freeland extended his unbeaten streak to 10 starts, and the Rockies beat the Diamondbacks 2-0 Sunday to stay 1 1/2 games behind the Los Angeles Dodgers in the NL West and 1 1/2 games back of St. Louis for the NL's second wild card. ''Arizona's lineup, we all know it can wake up at any moment and throw four or five runs on you whenever,'' Freeland said.
