Andy Murray has progressed to the fourth round of the Australian Open after a hard-fought 6-3, 6-4, 7-5 win over Lithuania's Ricardas Berankis. The third seed and Britain's No 1, will now face either France's Gael Monfils or Gilles Simon  next.
"We know each other pretty well. He works extremely hard. He hits the ball very flat, takes it early and on this court, playing pretty quick, it was tough. I was struggling [after first set], he was making me pretty uncomfortable with his style. I need to strike the ball better. My timing was off. I was leaving the ball very short," Murray said after the game.
The morning session had one relatively major upset - the defeat of sixth seed Juan Martin del Potro. The 2009 US Open champion lost 6-3, 6-3, 6-7(3), 3-6, 6-3 to unseeded Jeremy Chardy of France.
Also eliminated was Marin Cilic ; the Croatian was beaten in five sets by Italy's Andreas Seppi . There was better news for Jo-Wilfried Tsonga though. The seventh seed breezed past Blaz Kavcic of Slovakia in straight sets and will now play countryman and ninth seed Richard Gasquet, who dropped a set beating Ivan Dodig of Croatia.
Meanwhile, women's world No 1, Victoria Azarenka of Belarus, was made to fight for her fourth round slot. She eventually beat unseeded American Jamie Hampton 6-4, 4-6, 6-2 and will now play Elena Vesnina, after the Russian eliminated Italy's Roberta Vinci .
Third seed Serena Williams also marches on, with an emphatic 6-1, 6-3 win over Japan's Ayumi Morita. Williams will now play Maria Kirilenko  of Russia, who beat Yanina Wickmayer  of Belgium.
