HOUSTON, TXIn a historic development in the 2005 Major League Baseball postseason, Fox executives announced that the Chicago White Sox, who defeated the Houston Astros in four games after a 1-0 victory Wednesday, must now play the New York Yankees in the best-of-seven 'Real World Series' beginning Saturday night at 8 p.m., in order to determine the actual world champion. 'The White Sox must complete one final challenge before they may be crowned true champions,' Fox president Peter Liguori announced over Minute Maid Park's PA system, interrupting the White Sox's celebration. 'The Yankees are the keepers of the Real World Series trophy, and in order to win it, the White Sox must travel to New York and beat Derek Jeter, Alex Rodriguez, Randy Johnson, and the other formidable, marketable stars who await their arrival.' Liguori added that, in the event that the White Sox decline the challenge, the Red Sox have been scheduled to stand in for them.
