London - Dominika Cibulkova shrugged off a furious line call controversy to power into the Wimbledon quarter-finals with a 6-4, 6-1 rout of Taiwanese giant-killer Hsieh Su-Wei on Monday.
Cibulkova was furious when Hsieh successfully persuaded the umpire to replay a point that was initially called in the Slovakian's favour and would have given her three set points in the opening set.
But the 29-year-old challenged her anger to crush Hsieh - who had shocked world number one Simona Halep in the previous round.
Cibulkova is ranked 33rd in the world and controversially missed out on being seeded at Wimbledon when tournament officially moved up seven-time champion Serena Williams into the seedings despite the American being ranked outside the top 150 following her maternity leave.
Although Cibulkova complained about the decision, the former Australian Open finalist has refocused well enough to make her third Wimbledon quarter-final.
She faces Latvian 12th seed Jelena Ostapenko, a former French Open champion, for a place in the semi-finals.
