Defending champion Victoria Azarenka and five-time winner Serena Williams both recorded easy second-round victories, while Roger Federer also cruised through on a humid day four at the Australian Open.
Britain's Andy Murray also won comfortably while Laura Robson overcame world number eight Petra Kvitova in a three-hour battle to join Heather Watson in the third round at Melbourne Park.
Rod Laver Arena
Victoria Azarenka (Blr)  beat Eleni Daniilidou (Gre) 6-1 6-0
The defending champion powered to victory in 55 minutes to reach the third round. The world number one will next play American Jamie Hampton in the next round.
"I definitely stepped it up from my first match, and I was in the zone trying to execute all of my shots," said the Belarusian. "I was trying to make everything happen, and that's what I'm happy about."
"It was pretty hot. That's why I was trying to play fast. The first match I got a little bit sunburned and you don't want to make that mistake again."
Serena Williams (US)  beat Garbine Muguruza (Spa) 6-2 6-0
The third seed brushed aside any injury worries as she raced into the third round. The American hurt her ankle in the first round but was moving freely in her victory over the Spaniard.
The only mishap came when Williams hit herself in the mouth with her racquet. "One day I twist my ankle, today I hit myself in the face - I don't know what's going to happen on Saturday," she said.
"I'm hoping maybe I'll just hit some winners. I thought if there's swelling, at least I'll get super-sexy lips, right?"
Williams next plays Japan's Ayumi Morita as she continues her bid for a 16th Grand Slam title and a sixth at Melbourne Park.

Former world number one Wozniacki produced a good display to see off her resilient 16-year-old opponent. Vekic is based in London and is coached by Tim Henman's former coach David Felgate.
"I'm starting to feel seriously old because all the players at a physio session recently were younger than me," said Wozniacki. "I was even asked about retiring but I'm only 22!"

Date-Krumm, who has attributed her longevity to leading a simple life, said she gets a lot of support from fellow players. "Everybody says to me, 'You are crazy'. First word is always, 'You are crazy'. But they support me a lot," she said.
