World number one Aryna Sabalenka claimed her second title of the year by beating Jessica Pegula 7-5 6-2 in the women's Miami Open final.
There were seven breaks of serve in a hard-fought first set, which swung the way of both players, before the Belarusian won a game to love on Pegula's serve.
Sabalenka's power got her out of trouble on a number of occasions while Pegula's struggles to hold her own serve, along with her inability to deal with the force of her opponent's game, proved the world number four's downfall.
Her frustration grew as Sabalenka took control of the second set.
