ATP tour site gives very little information:-
Started playing tennis aged five with his parents, who played tennis for fun…Father, Jerzy, and mother, Anna Szalbot, were both professional volleyball players…Idol growing up was Pete Sampras…Likes all surfaces and favourite shot is forehand…Hobbies include computers and computer games…Considers himself very skilled with computers in general…
My guess is that there's something wrong with those ytd figures
It's alright, I'm talking pish! Plays on the challenger circuit! Genius!
