Number eight seed Victoria Azarenka lost her cool but still managed to overcome a spirited challenge from Nadia Petrova to reach the Wimbledon quarter-finals.
Azarenka had already won the opening set on a tie-break when she lost her discipline in the second.
The Belarus player, unhappy with a line call, accused the umpire of ‘ruining the game’ before going over to sarcastically shake the hand of the line judge.
Azarenka's tantrum occurred at 4-2 down in the second set as she struggled to get on top of Petrova's game. She went on to lose the set 6-2.
But in a one-sided final set on Court Three, Azarenka's class told and the Russian closed the match out to win 7-6 (7/5) 2-6 6-3.
She now faces Serena Williams in the last eight.
