Paula Badosa overcame a slow start to take down Belarusian top seed Aryna Sabalenka after Maria Sakkari continued her dominance of Iga Swiatek in the round-robin stage of the WTA Finals in Guadalajara, Mexico, on Thursday.

Badosa stunned world No.2 Sabalenka 6-4, 6-0 after winning the last 10 games, while Sakkari secured a comfortable 6-2, 6-4 win over Poland’s Swiatek.

Badosa was 2-4 down in the first set but the Spaniard withstood Sabalenka’s early power to take the opening set.

The 23-year-old, who lifted the Indian Wells title last month, closed out the match with a bagel in the second set as she celebrated a win under the lights on her WTA Finals debut.
Asked how she bounced back from her shaky start, Badosa said: “I said to myself, okay, now you have to be at her level, aggressive, because she was being very aggressive...I said, ‘Now you have to change, stop waiting for her miss and go for it’. That’s what I did.”

Earlier, Greece’s Sakkari got an early service break to take a 2-1 lead and grabbed the first set when Swiatek sent a forehand into the net when returning a second serve.
Swiatek improved in the second set but Sakkari converted her third break point opportunity for a 4-3 lead that looked decisive given Sakkari’s dominant serving.

The Greek won 26 of 27 first serve points and was never broken in the contest played on the purple court in the high-altitude Mexican City. Before match point, Swiatek appeared to start crying and after clinching victory Sakkari comforted her at the net with a hug.

“I saw that she was struggling. It wasn’t a nice thing to see from the other side of the net,” Sakkari said.
