Heard Stefan Kozlov hit with Roger Federer, several times, and Henrik Wiersholm hit with Novak Djokovic at the US Open. Obviously a fantastic experience for both of them and I expect motivational.
Saw in the NY Times that John McEnroe spends time with Noah Rubin on a regular basis.
Just wondering - do the top US players take the time to hit with the juniors on a regular basis? I would like to so.
