Baseball is a game of tradition. And since their inception in 1962 the Astros (then Colt 45s) have played in the National League. All of their rivalries and history has occurred in the National League. Also, moving them to the AL West would require a good portion of their games to start too late to watch or be reported in the newspaper the next day, as they would start at 9 pm cst. This would put an additional strain on the team and its fans. So, please, Mr Selig, respect tradition and leave the Astros in the NL.
