Maria, Rafa march on

EUGENIE BOUCHARD

Maria Sharapova was all business as she raced into the Australian Open quarterfinals 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.
Three-time runner-up Andy Murray rode his luck to fight back and win a titanic four-setter over Grigor Dimitrov.
Sixth seed Murray beat the 10th seeded Bulgarian 6-4, 6-7 (5/7), 6-3, 7-5 and will now play Australian teenager Nick Krygios in the last eight.
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 semifinals.
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.
Australian teenager Nick Kyrgios fought back from match point down to beat Andreas Seppi in five sets to reach the last eight.
The 53rd-ranked Kyrgios defeated the 46th-ranked Italian, who beat Roger Federer in the last round, 5-7, 4-6, 6-3, 7-6 (7/5) 8-6 and will play either Andy Murray or Grigor Dimitrov in the last eight.
The popular Bouchard is widely seen as a future major champion after her semifinal 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.
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 semifinals.
Makarova blitzed unseeded German Julia Goerges 6-3, 6-2.
