Serena Williams continued her role of loose cannon in the women's draw by shocking in-form 11th seed Jelena Jankovic 6-3 6-2.

Serena Williams continued her role of loose cannon in the women's draw by shocking in-form 11th seed Jelena Jankovic 6-3 6-2 in the fourth round of the Australian Open on Sunday.

The unseeded two-times former champion put on a formidable display of hitting and phenomenal chasing to overcome the fancied Serb in 83 minutes on Rod Laver Arena.

"I like being a dangerous floater," Serena, who is currently ranked 81st, told the crowd.

The 25-year-old American, champion in 2003 and 2005, will now play Israel's 16th seed Shahar Peer for a place in the semi-finals.
