(Reuters) - Third seed Agnieszka Radwanska stormed into the semi-finals of the China Open on Thursday with a 6-1 6-2 win against Yaroslava Shvedova, while American Madison Keys edged past Petra Kvitova 6-3 6-7(2) 7-6(5).

Radwanska will next face Elina Svitolina of Ukraine, who followed up her surprise win over world number one Angelique Kerber by easing past Australia's Daria Gavrilova 7-6(3) 6-1.

Due to Thursday's rain in Beijing, Shvedova was forced to play twice, earlier beating Alize Cornet 6-2 6-4.

Fatigue appeared to catch up with Shvedova as Radwanska lost just three games to seal her third China Open semi-final in the last four years.


The eighth-seeded Keys led by a set and a break and appeared to be in control of her quarter-final clash against Kvitova, but the Czech, winner of last week's Wuhan Open title, fought back to level the match in a tiebreak.

The 21-year-old Keys raced to a 3-0 lead in the deciding set, but was once again pegged back by the 14th-seed. Keys eventually held her nerve to triumph in a tiebreak after 2 hours and 41 minutes on court.

Keys, who edged closer to qualifying for the WTA season-ending finals in Singapore, will next face Britain's Johanna Konta.

Konta lost the first four games against home-favorite Zhang Shuai, but then reeled off 12 in a row to win 6-4 6-0.

"Jo is playing really well," Keys told the WTA website (

"I mean, at this point everyone's trying to qualify, everyone's trying to play their good tennis at the end of the year.

"Pretty much whoever you play is going to be a tough match."
