World number two Aryna Sabalenka started her Miami Open campaign after an emotional week with an impressive win over her close friend Paula Badosa.
Two-time Australian Open champion Sabalenka, 25, played her second-round match four days after the death of her former partner Konstantin Koltsov.
Koltsov, an ex-ice hockey player, died in Miami aged 42 in what police described as an "apparent suicide".
Sabalenka decided to play the event and won 6-4 6-3 against Spain's Badosa.
The pair have described themselves as "best friends" on the WTA Tour, sharing a long and warm hug at the net after Belarusian Sabalenka secured victory to reach the last 32.
