This is the Rockies third postseason appearance in the franchise's 17 years. They swept the Phillies and Arizona in the 2007 playoffs before getting swept by Boston in the World Series.

On Wednesday, during game one, the Phillies shut down the Rockies. One strike away from a shutout, Cliff Lee stepped off the mound, took a deep breath and allowed himself to enjoy the moment. Quite a debut for a postseason rookie.

Lee dominated the Rockies, tossing a five-hitter, and the Phillies began their World Series title defense with a 5-1 victory in their playoff opener.

Raul Ibanez had two hits and two RBIs, and Ryan Howard and Jayson Werth drove in runs with key extra-base hits off 15-game winner Ubaldo Jimenez.

Lee, the reigning American League Cy Young Award winner, struck out five and had no walks in his first career playoff start. He retired 16 straight batters at one point until Garrett Atkins hit a wind-blown double in the seventh. Lee lost his shutout when Troy Tulowitzki doubled in a run with two outs in the ninth.

A sellout crowd of 46,452 -- the largest in the six-year history of Citizens Bank Park -- rocked the ballpark, waving their white-and-red "Fightin' Phils" towels. The Phillies were 7-0 at home last October and set a franchise attendance record this season.

First pitch is at 12:37 p.m.
