Sabalenka, in her most difficult week, said goodbye to the WTA 1000 in Miami with a fit of fury: she crashed her racket against the cement after the defeat with Kalinina. The Belarusian, number two in the world ranking, fell 6-4, 1-6 and 6-1 in the third round.

Last Monday she had suffered the death of her ex-boyfriend, Konstantin Koltsov. Local police attributed the death to an "apparent suicide" after jumping from a Miami hotel room.
