Daniel Donovan Naulty (born January 6, 1970) is an American former Major League Baseball pitcher who is now a pastor.

After just one season in New York City, Naulty was traded to the Los Angeles Dodgers for minor league first baseman Nick Leach.

He soon caught on with the Kansas City Royals, however, after just 1.2 innings with the Omaha Golden Spikes, in which he gave up eight walks and nine earned runs, he was released.

George J. Mitchell contacted Naulty in January 2007 as part of his investigation of performance-enhancing drug use by Major League Baseball players.

He is one of few former and current baseball players interviewed by investigators to admit to using steroids, beginning in 1993 as a minor leaguer and continuing through his major league career.

Shortly after being drafted, he realized that in order to compete, he needed to throw harder, and add muscle to his thin 6'6" frame.

The negative impact of his drug use hit him later in his career when he thought about the fact that he took a roster spot from another player who was competing naturally.
