Gulbis has a very high ball toss I noticed it the other day. Even higher than Berdych. Under windy conditions he will have a tough time holding his serve. Very risky high ball toss IMO. I am not sure why coaches don't address that particular aspect of the game. I've in fact seen it in quite a few players.
A couple of break of serves by Berdy and Federer in the meantime so back to on serve again, 4 all, 2nd set.
