Sabalenka keeps emotion in check as she beats Badosa

MIAMI, United States -- World number two Aryna Sabalenka returned to the court for the first time since the death of her former boyfriend earlier this week and kept her emotions in check as she beat Spain's Paula Badosa 6-4 6-3 on Friday (Saturday, Manila time.)

After six hours of rain delays, Sabalenka walked onto the court wearing an all-black outfit, a choice matched by her close friend Badosa.

Two-times Australian Open winner Sabalenka on Wednesday said she was "heartbroken" by the death of former boyfriend Konstantin Koltsov in a statement on Wednesday, where she revealed they had not been a couple at the time of his death.

Koltsov died on Monday with Miami police saying he had jumped from the balcony of a room at an resort in an "apparent suicide."

The former NHL ice hockey player and coach, was 42 years old.

Sabalenka made a slow start to the match but broke to go 4-3 up in the first set and never looked back from that point on.

The Belarusian then broke in the third game of the second set with a superb cross court forehand winner and showed too much power for her Spanish opponent as she wrapped up the win in one hour 22 minutes.

The two players embraced at the net before leaving the court without an on-court interview. Sabalenka has asked the WTA to be excused media duties at the tournament.

Badosa said she was not surprised by the way Sabalenka was able to maintain her focus and deliver a solid performance.

"She is a very, very strong woman, strong personality. You can see it on the court...I know her off court so it doesn't surprise me at all," she said.

"I knew she was going to play very well or like normal. I told her I wish her the best and let's see if she can go deep in this tournament," added the Spaniard.

Badosa had said before the match that she expected it to be "uncomfortable"  playing against Sabalenka given her friendship with the Belarusian.

- Mental strength -
But she said their professionalism and mental strength had shown itself.

"Honestly, both of us are pretty strong mentally. We're strong women and she proved it and I proved it," she said.

"We knew how to disconnect in that two hours for the match. She played really well and I played really well given from where I am coming from (with injuries)," she added.

"All that comes from knowing that we've been through a lot in our lives and we're strong women. We knew how to separate (things) in that moment," she said.

American Coco Gauff, the third seed, had little trouble in her test against Argentine Nadia Podoroska winning 6-1 6-2 in one hour 16.

Later on Friday, top-ranked Iga Swiatek is scheduled to face Italy's Camila Giorgi while Naomi Osaka of Japan takes on Ukraine's Elina Svitolina in later matches.

Men's world number three Jannik Sinner of Italy is scheduled to face compatriot Andrea Vavassori while fourth-ranked Daniil Medvedev of Russia takes on Hungarian Marton Fucsovics.

Further rain and possibly storms are forecast in the Miami area for later on Friday however.
