Li avenges US Open defeat by Robson to reach last 16
Li avenged a third-round loss to Robson last year’s tournament and will next face either Japanese qualifier Kurumi Nara or Serbian ninth seed Jelena Jankovic for a berth in the quarter-finals.

Chinese fifth seed Li Na advanced to the fourth round of the US Open on Friday, smacking 11 aces in a 6-2, 7-5 victory over British teen Laura Robson.
Li avenged a third-round loss to Robson last year’s tournament and will next face either Japanese qualifier Kurumi Nara or Serbian ninth seed Jelena Jankovic for a berth in the quarter-finals.
“I was really happy how I was hitting on the court,” Li said. “And I thought I served really well.”
Connecting on 65 per cent of her first serves and winning all nine points when she came to the net, the 2011 French Open winner took control early and kept it most of the match.
Li said that even her coach, former Justine Henin mentor Carlos Rodriguez, would have to say he liked her effort, even though she said he would have a different message for her during practice.
