SINGAPORE: Red-hot world number three Karolina Pliskova has vowed to keep her foot on the accelerator after crushing Garbine Muguruza on Tuesday to become the first semi-final qualifier in the WTA Finals.
Pliskova, who is in contention to finish world number one, continued her stranglehold over the Spaniard with a 6-2, 6-2 victory in just 62 minutes. The Ukrainian has not dropped a set from her two games to ensure she finishes top of the White Group.
She will play her final round robin match on Thursday against winless number seven seed Jelena Ostapenko, who has been eliminated.
