Barty beats injured Andreescu to claim Miami Open title for second time

• World No 1 wins 6-3, 4-0 after opponent withdraws
• It's never the way you want to finish a tennis match'

The world No 1 Ashleigh Barty defended her Miami Open title in less than ideal circumstances after Bianca Andreescu was forced to retire from their final following an ankle sprain in the second set as Barty led 6-3, 4-0.

Barty had opened the match with a faultless display of attacking tennis for an hour, dominating with her serve and forehand as she moved to a 6-3, 2-0 lead. However, as Andreescu attempted to hold off a double break in the second set, she tumbled while chasing a ball and turned her right ankle. After a medical timeout, she eventually retired.
