Path to the NLDS: Houston (89-73) finished second in the NL Central and won the Wild Card; Atlanta (90-72) won the NL East by two games
After offense was much of the story in the first three games, neither the Astros nor the Braves could manage to muster any late in Game 4 as it took 18 innings for the Astros to pull out a 7-6 victory and advance to the NLCS.
Game 4 featured 14 pitchers, with Astros Game 2 starter Roger Clemens finishing the game and earning the victory for Houston.
The Astros were down 6-1 against Braves starter Tim Hudson in the eighth inning when Lance Berkman hit a grand slam to narrow the gap to one. Brad Ausmus tied it in the ninth with another homer. Both teams were then held quiet for another nine innings until pinch-hitter Chris Burke (batting in Berkman's place in the lineup) hit a series-clinching walk-off homer off Atlanta's Joey Devine.
