(Reuters) - Iga Swiatek overcame a lengthy rain delay and a stern test from Karolina Muchova to seal a 6-1 4-6 6-4 victory at the Canadian Open that will assure the Pole retains her number one ranking when the U.S. Open warm-up event concludes.

Riding the momentum from her fourth title of the season last week at her home tournament, the Warsaw Open, Swiatek looked poised for easy passage breezing through five straight games breaking Muchova twice to claim the first set.
