Naomi Osaka’s run at the Qatar Open ended in the quarter-finals with a narrow defeat by Karolina Pliskova.

The former world number one was through to the last eight at a tournament for the first time in nearly two years following her maternity break but she could not capitalise on good starts in both sets.
