Agree about the grunting. It's bad enough when they grunt hitting the ball but some of the grunts last until their opponent hits the ball which is just unsporting conduct as far as I'm concerned.
Having said that, and agreeing with DM above, all of the women's games I've watched on and off today have all been excellent. Radwanska, Kerber and now the Wozniacki game. Minimal grunting and some fantastic tennis.
Edit: Cameraman's on form today, picked out some right stunners.
Edit: Federer through in straight sets but the bottom half of the draw is ridiculously tough compared to the top so if Federer's to win it again he'll have to beat Dimitrov, Raonic/Zverev, Djokovic and then Murray or Nadal assuming they all make it.
