An agitated Daniil Medvedev teed off at the chair umpire and lost his cool in the heat before steadying to claim a 6-2 7-6(4) 6-7(4) 7-5 win over Maxime Cressy and book his second Australian Open quarter-final on Monday.
The Russian second seed found the American serve-and-volley exponent a tough nut to crack at Margaret Court Arena and his frustration spilled over after losing the third set.
Apparently refused a request to leave the court to freshen up, Medvedev barked at the French chair umpire Renaud Lichtenstein and complained that Cressy was spending too much time between serves.

Medvedev`s frustration only grew as eight break points slipped through his fingers in the fourth set before he finally slipped a forehand past the American in the 11th game to take his serve.
Medvedev wrapped up proceedings with a slew of huge serves before stepping in to thrash a forehand winner on match point.
