But the 29-year-old channeled her anger to beat 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.
