Garbine Muguruza has overcome Simona Halep in the The Western and Southern Open final with a scintillating performance to record a 6-1, 6-0 win over the Romanian.

Halep was aiming to claim the world No.1 ranking by winning the title, but she never stood a chance, with Murguruza in a rare vein of form.

The title is Muguruza's first in the US and her second of the year after her Wimbledon triumph.

Meanwhile, in the men's draw, Australian Nick Kyrgios went down to Grigor Dimitrov 6-3, 7-5.
