Poles apart as Swiatek rolls on at Wuhan Open

She maintained her momentum by winning four straight games to start the second set, before Frech made it 4-1.

Swiatek is seeded No.7 in the WTA 1000-level event.

She reached the quarter-finals of the recent China Open in Beijing.

Swiatek next faces either Ashlyn Krueger or Lanlana Tararudee. 

The Pole is in the same quarter as top-seeded Aryna Sabalenka, who faced Ann Li later on Wednesday as she looked to join Swiatek in the round of 16.

In other second-round matches, No.5 Elina Svitolina, of Ukraine, scored a 6-2 5-7 6-2 win over Russia's Liudmila Samsonova, while British world No.170 Sonay Kartal notched a surprise 6-0 7-5 win over ninth-seeded Belinda Bencic of Switzerland.

Italian 15th seed Jasmine Paolini beat Czechia's Nikola Bartunkova 7-6 (7-5) 6-3.
