BEIJING, China (AFP) — Iga Swiatek hailed a "really big" victory after she delivered a dominant performance to win the China Open on Sunday, beating surprise package Liudmila Samsonova in straight sets to crown a resurgent run of form.

The world No. 2 triumphed 6-2, 6-2 in Beijing to take the first China Open women's title since the pandemic, after Beijing lifted its isolationist zero-Covid policy.

The victory capped a strong showing for four-time Grand Slam champion Swiatek, who was deposed as the world's top-ranked player by Aryna Sabalenka last month.

The 22-year-old broke Samsonova's serve in the sixth game and sealed the opening set when the unseeded Russian slammed a forehand into the net.

Swiatek looked assured throughout and quickly notched another break in set two when her error-prone opponent fired another forehand wide.

And when Samsonova sent an ill-advised drop-shot into the net to hand her the victory, the Pole doubled over with emotion before a delighted crowd.

"For sure, this is really big for me. Winning this title is something I never would have thought at the beginning of the tournament," Swiatek said at a post-match news conference.

"(It) will give me confidence… that there's always a chance to overcome and work on what you do or what you're feeling," she said.

"You can always get better and sometimes it's pretty easy, but we pretend to make it more complicated in our heads," she added.

"I'm really happy that I just focused on hard work and it paid off — maybe not instantly, but I'm happy that after the US Open I just got back to basics and just worked really hard tennis-wise."

Swiatek was the favorite to win the final after handing US Open champion Coco Gauff her first defeat in 17 matches in the final four on Saturday.

Sabalenka had been knocked out in the quarter-finals by fifth-ranked Elena Rybakina, who was in turn dumped out by Samsonova in the other semi-final.
