Istanbul, Turkey (SportsNetwork.com) - Chinese star Li Na prevented world
No. 2 Victoria Azarenka from reaching this weekend's semifinals at the season-
ending $6.5 million WTA Championships.
Li was joined in the semis by fifth-seeded former Wimbledon runner-up Petra
Kvitova, who snuck past eighth seed Angelique Kerber 6-7 (3-7), 6-2, 6-3.
