Tomas Berdych dampens Australia's day at Melbourne Park

The Czech seventh seed, who announced his engagement to girlfriend Ester Satorova earlier this week, was in no mood to extend that sentimentality to the local fans cheering Tomic with a clinical 6-2 7-6(3) 6-2 victory.

The tall 29-year-old destroyed Tomic's serve in a quick-fire match with two thirds of the points decided in rallies of less than four shots to set up a quarter-final with either third seed Rafael Nadal, who was equally impressive in his 7-5 6-1 6-4 victory over South Africa's Kevin Anderson.

The local fans still have the opportunity to celebrate their national holiday on Monday with at least one player advancing to the quarter-finals with Nick Kyrgios, the last Australian remaining in either draw, playing Andreas Seppi later on Sunday.
