London, June 20 (IANS) China's Li Na advanced to the quarter-finals of the Eastbourne International tennis tournament as her French opponent Marion Bartoli pulled out due to a viral infection.
Li, the second seed, was told about the development by her coach barely 10 minutes before the match started Wednesday, reports Xinhua.
Bartoli, ranked 15th in the world and the 2011 champion, said in a statement: "I'm really disappointed to have to withdraw, since it's so nice here and I've always done well at this tournament."
