Have just watched a young Swiss guy (just 20) called Adrien Bossel come through 2 qualifying matches at Sheffield Futures, beat Konstantinos Kalaitzis (GBR) #1249 and Miles Armstrong (AUS) #718.
He is a left hander and I cant believe he's only got 1 ranking point, really enjoyed seeing him, probably not got enough power to make it at ATP level, but a good player to watch with a nice touch, pulled off a fantastic backhand lob at break point in the penultimate game of the match against Armstrong.
Doesnt answer your question about next Davis Cup star but enjoyed watching him anyway.
All the best!
bossel actually got through the qualies!!!
he beat pavlovs 3-6 6-3 6-1!
Good luck for the main draw!
Unfortunately thomet lost in the 1st round of the qualies.
