Adam Daniel Greenberg is a former American professional baseball player. He was an outfielder for the Chicago Cubs of Major League Baseball in 2005 and was best known for being hit in the head in his major league debut on the first pitch of his first plate appearance. He was one of two players in league history to be hit by a pitch in their only plate appearance without ever taking the field, the other being Fred Van Dusen of the 1955 Philadelphia Phillies. However, a successful online petition drive in 2012 led to him getting signed by the Miami Marlins to a one-day contract. He had one at bat for the Marlins and struck out on three pitches. He agreed to a minor league contract with the Baltimore Orioles for 2013, but the option wasn't pursued. He also played parts of five seasons with the Bridgeport Bluefish of the Atlantic League of Professional Baseball near his hometown.
