Radwanska found herself down an early break to the WTA Rising Star at 3-2 but won four of the next five games to take the first set. It was smooth sailing in the second set for the Pole, as she went up 4-1 and went on to a 6-4, 6-3 triumph that saw her convert on all four of her break points. She even out-aced the big-serving American, four to three.

Radwanska is no stranger to success in Beijing, having won the title in 2011 and having been runner-up in 2009. Though she lost her opener last week in Wuhan, she still appears likely to secure one of the four remaining spots at the BNP Paribas WTA Finals Singapore presented by SC Global. In fact, she could qualify by reaching the final in Beijing.

Another WTA Rising Star fared better than Vandeweghe, as Madison Keys was a 6-3, 6-7(3), 7-5 victor over fellow American Alison Riske. Keys overcame two match points on her serve down 5-3 in the third set en route to beating her sometimes doubles partner for the third straight time.

Others moving on were WTA Rising Star Zarina Diyas, Romina Oprandi and Chinese wildcard Zhu Lin.

Diyas was a 6-1, 6-4 winner over Klara Koukalova. Oprandi topped Bojana Jovanovski, 6-2, 6-4, the exact same score she beat her by last time they played in Miami in March. Zhu was up 6-3, 3-3 on Anastasia Pavlyuchenkova when the Russian had to retire with dizziness, giving Zhu the best win of her career.

The night session saw Sabine Lisicki shake off a slow start for a 4-6, 6-2, 6-0 win over 16-year-old Chinese wildcard Xu Shilin. That set up a second round clash with No.8 seed and WTA Rising Star Eugenie Bouchard. And Carla Suárez Navarro beat Kirsten Flipkens, 6-2, 6-4.

Securing main draw berths with wins in the final round of qualifying were WTA Rising Star Belinda Bencic, Sílvia Soler-Espinosa, Polona Hercog, Bethanie Mattek-Sands, Mona Barthel, Xu Yi-Fan, Tsvetana Pironkova and Monica Niculescu
