Caroline Wozniacki breezed into the second round of the Australian Open on a baking hot day in Melbourne.
The 10th seed dropped only two games in defeating Spain's Lourdes Dominguez Lino 6-0 6-2.
She said of the conditions: "It was a little warm out there today. I put a (drink) bottle down on the court and it started melting a little bit underneath. It was great that I managed to finish it off in two sets and it wasn't too long."
Wozniacki is playing in her first grand slam since becoming engaged to golfer Rory McIlroy but insists she is as hungry as ever to try to be a grand slam force once more.
The 23-year-old has not reached the quarter-finals at one of the sport's four biggest tournaments for two years.
She said: "I think I'm in a very good place in my life right now, on the court and off the court. I know what I want. I want to improve all the time. I want to be the best."
There was a scare for eighth seed Jelena Jankovic when she fell during her match against Japan's Misaki Doi and needed treatment to her ankle, but she recovered to win 6-1 6-2.
Eleventh seed Simona Halep, who won more titles than any other woman except Serena Williams last season, was an even more emphatic winner, the Romanian defeating qualifier Katarzyna Piter 6-0 6-1.
