JOHANNA KONTA’S defence of her Miami Open title ended yesterday as US veteran Venus Williams beat the British number one 5-7 6-1 6-2 in their fourth-round match in Key Biscayne.

The result will see 11th seed Konta drop from 14th in the world rankings to outside the top 20.

Konta won last year’s Miami Open, beating Denmark’s Caroline Wozniacki 6-4 6-3 and becoming the first British woman to take the title.
