The third round came to a close on Saturday, with Dominika Cibulkova upsetting Carla Suárez Navarro.
Anastasia Pavlyuchenkova led Agnieszka Radwanska, 75 20, but ended up falling to the World No.5, 57 62 62.
Jelena Jankovic had a tough second set - she was down 5-2 - but she got past Kurumi Nara anyway, 64 75.
Garbiñe Muguruza had the victory of the day, battling back to take out Caroline Wozniacki, 46 75 63.
Muguruza is on a roll - she came in off her first WTA title at the lead-up tournament in Hobart.
Conchita Martínez, one of Spain's two greatest female players ever, was in the stands supporting her.
Meanwhile, the No.1 doubles team in the world - Sara Errani and Roberta Vinci - were at the WTA booth.
The Italians were there to promote the Road To Singapore, meet fans, sign autographs and pose for photos.
Errani and Vinci fell first round in singles but are still alive in the doubles draw this fortnight.
Meanwhile, on a day off from matches, Angelique Kerber went on a very special shopping spree...
Kerber celebrated her birthday on Saturday and was picking out a pair of sunglasses for the occasion.
The night match saw Yvonne Meusburger make her Grand Slam third round debut against Victoria Azarenka.
Azarenka was too tough on the day though - she won 11 games in a row from 1-1 to prevail, 61 60.
Azarenka, the two-time defending champion at the Australian Open, shared the love with her many fans.
And one of her biggest fans shared the love with her - Redfoo, now a strong member of Team Vika.
