This is the American college system, but I figured some people might be interested because lots of foreigners play in it, and plus two players who came out of the system last year (Isner and Anderson) have already reached the top 100 and an ATP final each. Jesse Levine played in college last year too and has since reached the top 150, winning 3 challenger tournaments. Lots of struggling young pros (A few come to mind pretty quickly) probably would've been better off had they gone to college.
Anyways, the NCAA Championships are underway and Somdev Devvarman of India, who plays for the University of Virginia, is playing John-Patrick Smith of Australia, who plays for the University of Tennessee, in the finals. Smith was a top 10 ITF junior player last year. It'll be interesting to see if he goes pro after his results this year. Devvarman is the defending champion. IMO he should've gone pro after winning last year, especially after seeing the success of Isner, Anderson, and Levine, but since he's a senior he'll be graduating, so I'm assuming he'll be joining the tour full-time. He's already played for the India Davis Cup team.
Devvarman beat Alex Clayton (USA) of Stanford in the semifinals, while Smith beat Andre Begemann (Germany) of Pepperdine. Finals are tomorrow. There are some interesting names and possibly some future top pros. Here's the draw:
