Never in more than 100 years of World Series history has a player made his major-league debut on the game's grandest stage. That could change this year if Kansas City Royals phenom Raul Mondesi Jr., gets into a game. Kansas City added Mondesi to its World Series roster on Tuesday, creating the possibility that the 20-year-old son of former Los Angeles Dodgers All-Star Raul Mondesi could be the first to debut in the series. The Royals play host to the Mets in Game 1 on Tuesday (8:07 p.m., FOX).
