It’s come down to a best-of-three series with a trip to the Fall Classic on the line. The Houston Astros beat the Cardinals 6-5 in game four, tying the National League Championship Series 2-2. St. Louis ran out to a 3-0 lead in the first. The inning included a two-run home run by Albert Pujols. The Astros got a run back in the bottom of the inning on an RBI double by Jeff Bagwell. The Cards reclaimed a three-run lead in the third thanks to a sacrifice fly by Jim Edmonds. But a two-run double by Lance Berkman in the bottom of the third cut the Cards’ lead to one. Pujols added his third RBI of the day on a single in the fourth, putting the Cardinals on top 5-3. But the Astros rallied in the sixth off Kiko Calero. A home run by Berkman and RBI single by Raul Chavez tied the game 5-5. In the seventh, Carlos Beltran connected again. Beltran belted his eighth home run of the postseason off Julian Tavarez. The eight homers ties a major-league postseason record. Beltran also set a new record by homering in his fifth straight postseason game. Brad Lidge picked up his second straight two-inning save, striking out Scott Rolen to end the game. Game five of the best-of-seven series is tonight in Houston. Woody Williams faces Brandon Backe. Game six will be played on Wednesday in St. Louis. If necessary, game seven would also be in St. Louis on Thursday.
