The Astros defeated the Cardinals 3–0 in Game 5 with Jeff Kent driving in the winning runs with a walk-off home run in the bottom of the ninth off Jason Isringhausen. Astros starter Brandon Backe took a perfect game into the fifth inning, when he walked Cardinals center fielder Jim Edmonds, and allowed only one hit (a single to second baseman Tony Womack in the sixth) in eight innings. The Cardinals' Woody Williams was nearly as effective, allowing only one hit (a two-out single to Jeff Bagwell in the first) and two walks over seven innings. Houston led the best-of-seven series 3–2 and was one win away from their first World Series appearance.
