Muguruza stays number one despite Ostapenko defeat
Garbine Muguruza held on to her status as world number one despite a quarter-final defeat to Jelena Ostapenko at the Wuhan Open on Thursday.
Simona Halep's challenge for top spot had been ended in the second round, but Karolina Pliskova remained a threat until she was beaten by Ashleigh Barty earlier in the day.
And it was just as well for Muguruza that the Czech lost her last-eight clash, as she threw away the advantage to lose 1-6 6-3 6-2 to French Open champion Ostapenko.
Muguruza dominated the first set, losing the opening game before reeling off six in succession to race into the lead.
However, the Wimbledon winner came under severe pressure on her own serve in the second and - in an almost a complete reversal of the first - she managed to hold on just one occasion.
It was a similar story in the decider, too. After opening with a break, Muguruza lost her way as Ostapenko grew in confidence.
The Latvian won a superbÂ six in a row to wrap up the match and her first victoryÂ over Muguruza in three attempts.
Ostapenko will meet AustralianÂ Barty in the semi-finals.
