- Former world No 1 beaten 7-6 (6), 7-6 (5) by Czech in Doha
- Swiatek, Rybakina and Pavlyuchenkova also reach last four
Naomi Osaka’s run at the Qatar Open ended in the quarter-finals with a narrow defeat by Karolina Pliskova.
The former world No 1 was through to the last eight at a tournament for the first time in nearly two years after her maternity break but she could not capitalise on good starts in both sets. Instead, it was Pliskova, champion at the Transylvania Open last week, who continued her winning run by triumphing in two tie-breaks for a 7-6 (6), 7-6 (5) victory.
