Novak Djokovic suffered a shock defeat by South African qualifier Kevin Anderson at the Sony Ericsson Open.

Defending champion Djokovic arrived in Miami as the form player having won in Indian Wells last week but lost 7-6 (7-1) 3-6 6-4 to the world number 122.

The third seed, who had a first-round bye, was broken in game five of the decider and Anderson served out to win.

In earlier women's matches, Justine Henin, Serena Williams and Svetlana Kuznetsova all made progress.

Belgium's Henin was playing for the first time since defeat by Francesca Schiavone in Dubai last month, and saw off Germany's Angelique Kerber 6-4 6-2.

"I feel much better physically today than I did a few weeks ago - that's for sure," said Henin, who has struggled with a knee injury.

"So we could see it in my serve, I can play with my forehand again and I feel that everything is better now."

Local favourite Williams thrashed Edina Gallovits 6-1 6-2, while third seed Kuznetsova beat Yung-Jan Chan 6-1 3-6 6-0.

"I love playing here," said Williams, who lives nearby in Palm Beach Gardens.

"I love having all my friends come and see me play. It's like playing at home."
