I looked this guy up on atptennis.com, and he is rising rapidly in the rankings, despite being about 200. He is only 20 years old, and he just got to the finals of Chennai, losing to Wawrinka 6 and 6. And the most interesting thing about this guy is that he is listed at 5 foot 4. Has anyone seen him play? He must be faster than heck to do so well at that height?
