Barty topples Sabalenka to seal semi-final spot
World number-one Ash Barty secured a place at the Miami Open semi-finals with a 6-4 6-7 (7-5) 6-4 win over Aryna Sabalenka.
With her ranking at the top of the WTA tour in jeopardy, the defending champion held her nerve to finish strongly, after dropping the second set to the powerful Belarusian.
Barty will take on the winner of the quarter-final between Anastasija Sevastova and Elina Svitolina in the semi-finals.
