Iga Świątek sheds tears of joy after winning China Open

Świątek shed tears of joy after her 69-minute masterclass, which left the four-times Grand Slam champion 465 points behind the top-ranked Sabalenka and with a big chance to leapfrog the Belarusian at the WTA Finals in Cancun, Mexico.

The season finale, where the top eight singles players and doubles teams in the world face off, begins on Oct. 29.

Beijing debutant Świątek was handed the first break of the clash in the sixth game when Samsonova produced a double fault and the 22-year-old then wrapped up the opening set without committing a single unforced error.

Świątek's superb serve proved to be her biggest weapon as she never faced a break point and raced ahead 4-1 in the second set before sealing the win with ease for her 16th title overall as world number 22 Samsonova made another error at the net.

"I'm very happy. For sure, it was the last thing I expected at the beginning of the tournament," Świątek said. "This match today, even though the score makes it seem like it was easy, it wasn't. It was really intense and Liudmila put pressure on me.

"I'm happy that I was solid and consistent and till the end I could keep my focus. At the end I felt really grateful for the support I get from my team because the last two weeks were not easy. So I was happy."

French Open champion Świątek also became the first player since American Serena Williams to claim five or more titles in successive years. Williams managed the feat in 2014 and 2015.

Świątek also became the player with the most WTA 1000 titles before turning 23 with six, eclipsing Caroline Wozniacki's five.

The 24-year-old Samsonova said she would have liked to put up more of a fight in the final but was pleased with her display through the tournament.

"It was an amazing week," said Samsonova, whose run to a second WTA 1000 final of the season ensured she will return to the top 20.

"I was in Tokyo last week and not playing my best tennis, but here I showed some decent tennis and I'm happy for this."
