1. Vital Statistics: Klahn was born on Aug. 20, 1990, in Poway, Calif., where he currently resides.

7. In His Own Words: "Growing up, I always knew I wanted to go to college. My parents have always stressed the importance of receiving a good education and keeping up with my studies, so going pro right from the juniors never crossed my mind," Klahn said to USTA.com about playing college tennis.
