Rayn nearly broke, Vasek managed a couple of very good first serves, held..... got to 30:30 on Ryan's serve - then suddenly fell to the ground in complete spasms - took several minutes to get going again - umpire gave him a time violation (cramp doesn't count), Ryan then served - ball looked out but called in - Vasek is shouting his head foo, standing on one leg - gets an unsportsmanlike conduct warning..... Ryan manages to hold
Just watched the end of that. Looked to me as a bit of gamesmanship from Pospisil as he'd clearly taken something to try and get through the cramp and he was trying to make the match long by complaining and waiting for it to kick in perhaps?
Great win regardless, he's certainly back to form!
