Defending champion Caroline Wozniacki was knocked out of the Australian Open as five-time Grand Slam winner Maria Sharapova provided a reminder of her ability with a three-set win.
Russia's Sharapova, seeded 30th, hit 37 winners in a 6-4 4-6 6-3 victory to reach the fourth round.
Wozniacki, 28, led 4-1 in the first set, only to see Sharapova battle back, reports BBC.
The third seed broke in the final game of the second to level, but Sharapova edged a tight third in Melbourne.
The 2008 Australian Open champion, 31, took her second match point to win in two hours and 24 minutes and set up a fourth-round meeting with Australia's Ashleigh Barty on Sunday.
"I haven't played many matches in the last year, especially against top players and these are the ones I train for, so it's really rewarding to win," said Sharapova, who served a 15-month ban for failing a drugs test.
Danish world number three Wozniacki, defending the ranking points won in Melbourne last year, is set to slide down the standings as a result of the defeat.
She was competing at a Grand Slam as the defending champion for the first time, but says the experience did not put on added pressure.
"I did not find it hard all all. I find it kind of pleasurable," she said.
"In tennis, you're one on one, you battle and you do your best. One day you win, some days you lose.
"I gave it everything I had today. She was just a little bit better than me and that was really it."
