Day 3 of the Aussie Open saw some new faces like Belinda Bencic push top players like Li Na hard.
And not everything went to form - No.15 seed Sabine Lisicki succumbed to the crafty Monica Niculescu.
But Serena Williams didn't hesitate to unleash her lethal game onto unheralded Serb Vesna Dolonc.
She had Rena's Army - what she calls her fans - supporting her from the sidelines on Rod Laver Arena.

Alison Riske - formerly a grass court specialist - reached the third round for the third straight major.
Casey Dellacqua, Australia's No.2 player after Sam Stosur, had her support from the crowd as well.
The left-handed Dellacqua upset No.18 seed Kirsten Flipkens in a one-hour, three-minute rout, 63 60.
Back in the third round of her home major, Dellacqua spoke to Rennae Stubbs before leaving the court.
Eugenie Bouchard also had huge crowd support in her match against former Top 20 star Virginie Razzano.
It was a nail-biting finish but the No.30-seeded Canadian won - and then got serenaded with O Canada.
Former Australian Open semifinalist Zheng Jie rallied from 4-1 down in the third to beat Madison Keys.
And one of the feel good stories of the day - Jelena Dokic returned to action in the doubles event.
