College
NCAA Men's Singles Title
Britton, at the age of 18, won the 2009 NCAA Men's Tennis singles championship as a freshman. He is the first Ole Miss men's tennis player to ever win a NCAA men's singles championship. Britton defeated Moritz Baumann of Wisconsin in the first round then beat Dominic Inglot of Virginia in the second round. In the third round, Britton sent Rice senior Bruno Rosa out of the tournament in straight sets, and then he beat Stanford’s Alex Clayton in the quarterfinals. To advance to the NCAA championship match, he defeated Blake Strode of Arkansas with a straight set win. To win the championship, Britton defeated Ohio State senior Steven Moneke, making him the first American-born player to win the NCAA singles title since Alex Kim of Stanford in 2000. The championship win also makes him the first freshman since 19-year-old Cecil Mamiit of USC in 1996 and the first non-seeded player since Luke Smith of UNLV in 1997. He is the youngest of the three freshmen to win the singles title, including John McEnroe, who was 19 when he won it for Stanford in 1978 – making him the youngest player ever to win the national championship.
Leaving college
After only one semester in college, Britton announced on July 1, 2009, that he would not return to Mississippi but would instead turn professional and had already signed a contract with a sports agency, Octagon Worldwide. He received a wildcard into the 2009 U.S. Open where he played #1 seeded and ranked Roger Federer in the opening round. Federer won in straight sets as expected, but Britton did manage to break Federer twice.
Britton began playing tennis when he was 4 years old. Britton was home-schooled starting in the seventh grade. Because he was traveling extensively for tennis, he completed his high school education through the Alpha Omega Online Academy. Devin’s parents are Scott and Cindy Britton. He is the youngest of three children. He has two older sisters, Tara Chez and Katie. Devin trained at the IMG/Bollettieri Tennis Academy in Bradenton, Florida where he was coached by Nick Bollettieri, David Amye and Gabe Jaramillo. At Ole Miss, he was coached by Billy Chadwick. His serve and volley style is rare among modern players.
