Chinese tennis player Li Na has beaten former Wimbledon champion Petra Kvitova 6-4, 6-2 to reach the final of the WTA Championships in Istanbul.
According to Sport24, already the first Chinese singles player to win a Grand Slam, and now assured of a season-end highest-ever world ranking of at least number three, Li's latest victory was a reward for positive early groundstroke attacking from both wings and a ratio of unforced errors significantly lower than Kvitova's.
Earlier, Serena Williams also overcame some physical and emotional problems to beat Jelena Jankovic in three sets and set up a final clash with Li.
The WTA Championships in Istanbul is the tour's flagship season-ending tournament.
