Bulgarian Grigor Dimitrov is officially on TSF radar after the Bulgarian teenager took a set off Rafael Nadal in the second round of the ABN AMRO World Indoor Tournament.
Dimitrov turned pro last year after taking the junior Wimbledon and U.S. Open titles. He’s currently ranked in the 400s. In case you’re wondering, he turns 18 in May.
