Guerrero had an up-and-down 2005 postseason, batting .389 in ALDS victory over the New York Yankees, but just .050 in the ALCS against the eventual world champion Chicago White Sox. He fared better in a national TV ad for Pepsi with the Yankees' third baseman Alex Rodriguez; the two engaged in a personal home run competition that ended up with the moon being broken. Guerrero also appeared at Game Four of the 2005 World Series, where he was introduced as a member of Major League Baseball's Latino Legends Team.
