On April 5, 2005, the defending N.L. Champion Cardinals opened up the season with a 7-3 win over the Astros in Houston. The NLCS rematch was highlighted by a three-run home run by Jim Edmonds in the first inning. In the end all three Cardinals outfielders put one in the seats, as Reggie Sanders and Larry Walker both joined Jimmy Ballgame in the home run department. The win was the first of 100 wins for the Cardinals, and it snapped an 18 game home winning streak for the Astros.
