Curtis played all four games of the 1999 World Series in left field. He is best known for hitting a walk-off home run in Game 3 of the series against the Atlanta Braves; it was his second home run of the game. When, immediately following the home run, NBC sportscaster Jim Gray sought to conduct an on-field interview with Curtis, Curtis refused to talk with him. He indicated that this was in response to Gray's earlier, pointed interview on gambling with Pete Rose, a former baseball player who had been banned from involvement with MLB because of his gambling history. Curtis told Gray: "I can't do it. As a team, we kind of decided, because of what happened with Pete, we're not going to talk out here on the field". Then-Yankees manager Joe Torre later said there was no such unified effort to snub Gray from either Yankees players or front office staff, and that Curtis had acted alone.
