Pitcher Alan Horne has gone from first round draft pick to college baseball star to Tommy John surgery during the course of his career. As of 2008, he is playing AAA ball in the New York Yankees organization.
Along with future big leaguer Jeff Mathis, Horne led Marianna High School to the Florida Class 3A Final Four in all four years he played there, and the school captured the state title in his junior year. After graduation, he was selected by the Cleveland Indians in the first round of the 2001 amateur draft but opted to play college ball at the University of Mississippi instead.
At Ole Miss, Horne was rated one of the top prospects in the Southeastern Conference, but after two seasons, he was sidelined by Tommy John surgery. After playing at Chipola Junior College in 2004, he was selected by the Anaheim Angels in the 30th round of the 2004 amateur draft but did not sign with the club. Instead, he transferred to the University of Florida, where in 2005 he won 10 games and struck out 108 and reached the Finals of the College World Series.
Horne was then selected by the New York Yankees in the 11th round of the 2005 amateur draft. He was signed by scout Brian Barber and made his pro debut the next summer with the Tampa Yankees, going 6-9 with a 4.84 ERA and 122 strikeouts. He played for the Trenton Thunder in 2007, going 12-4 with a league-leading 3.11 ERA and 165 strikeouts and being named Eastern League Pitcher of the Year. He began 2008 with the Scranton/Wilkes-Barre Yankees and was 1-0 in 2 starts before going on the disabled list in April.
