LONDON - Former world number one Victoria Azarenka has been knocked out of Wimbledon, losing 6-3 3-6 7-5 to Serb world No.45 Bojana Jovanovski.
Azarenka, twice a Wimbledon semi-finalist, had only returned to action at Eastbourne last week following a three-month lay-off caused by a left foot injury.
The 22-year-old Jovanovski has reached the third round for the first time and will next face Czech qualifier Tereza Smitkova.
Australian Open champion Li Na, a three-time quarter-finalist, swept to a 6-2 6-2 victory over Austria's Yvonne Meusburger, hitting 33 winners to just four from the world No.38.
Second seed Li, 32, goes on to face Barbora Zahlavova Strycova of the Czech Republic.
She says she's unconcerned about her 21 unforced errors.
"If you want to play more aggressive, this is the normal way," she explained.
Five-time champion Venus Williams, 34, and playing in her 17th Wimbledon, defeated pint-sized Japanese Kurumi Nara 7-6 (7/4) 6-1 in a battle of little and large on Court 3.
Williams will now face 2011 champion Petra Kvitova in the third round.
