Maria Sharapova was all business as she raced into the Australian Open quarter-finals on Sunday to set up a glamour showdown with Eugenie Bouchard, as Rafael Nadal continued his unrelenting Grand Slam march.
The Russian world number two ended Chinese hopes by swatting aside 21st seed Peng Shuai 6-3, 6-0 as she lifts her game the deeper she gets in the tournament.
It hands organisers a dream last eight clash between two of the most marketable players on tour with Canadian seventh seed Bouchard surviving a mid-match slump to defeat unseeded Irina-Camelia Begu of Romania in three sets.
Nadal, a 14-time Grand Slam champion, was dominant after a tight first set against power-hitting South African Kevin Anderson, running out a 7-5, 6-1, 6-4 winner and will next play Czech Tomas Berdych for a place in the semi-finals.
The consistent Berdych, who made the final four last year, ended Australian Bernard Tomic's tournament with a comfortable 6-2, 7-6 (7/3), 6-2 hit-out.
"After a tough period of time for me, it's a fantastic result and I'm very happy with the way I played today (Sunday)," said Spain's Nadal, who came into the tournament after a three-month injury layoff.
"It was probably my best match here this year so that's very important for me and very special."
Berdych, who has lost his last 17 encounters with Nadal, admitted he would have to be at the top of his game to win.
"I'm going to have to sit down with my team and prepare the right tactics," he said
"Whatever I need to do I'm going to be ready for it and will try to fight until the last point."
Another Australian, Nick Kyrgios, will attempt to down Roger Federer's shock conquerer Andreas Seppi of Italy later Saturday while Britain's Andy Murray has a tough task against 10th seed Grigor Dimitrov.
Sharapova, gunning for a sixth Grand Slam title and her first in Australia since 2008, said her match against Peng was tougher than the score suggested.
"I've always had a little trouble against Peng Shuai, she's a really tough competitor," she said.
The Russian added that Bouchard, the tour's most consistent performer at Grand Slams last year who pushed her in their French Open semi-final, would be another big challenge.
"She's been playing incredibly well, confident aggressive tennis. I have a tough match ahead of me."
Go for shots
The popular Bouchard is widely seen as a future major champion after her semi-final appearance at Melbourne Park last year, a feat she matched in Paris before making the Wimbledon final.
It didn't go all her way against Begu, who sparked to life in the second set to push the ambitious 20-year-old to a third before winning 6-1, 5-7, 6-2.
Bouchard has met Sharapova three times before and lost each one, a statistic that doesn't sit well with her.
"I think I've progressed a lot since then and I definitely want to keep playing my game no matter what," she said.
"Really take it to her, go for my shots. That's what I want to do on the court. And it's more fun when I play that way too."
Dangerous Romanian third seed Simona Halep also went through, battling past unseeded Belgian Yanina Wickmayer 6-4, 6-2 and will meet Russian 10th seed Ekaterina Makarova for a place in the semi-finals.
Makarova blitzed unseeded German Julia Goerges 6-3, 6-2 to maintain her no-nonsense form, having yet to drop a set.
It is the third time the Russian has made the quarters in Melbourne after strong runs in 2012 and 2013. She also appeared in the last 16 in 2014 and in 2011, making the Australian Open her most consistent major.
But Halep defeated her in their only previous meeting at New Haven in 2013.
"I have confidence I can beat her again but it's a quarter-final and it will be a tough match," said the third seed.
