Australia\'s Matosevic into Vienna quarter-finals

Australia\'s Marinko Matosevic knocked the last home player out of the Austrian Open on Thursday, defeating Dominic Thiem 6-3, 7-6 (7/5) to set up a quarter-final meeting with top seed Juan Martin del Potro. Matosevic, ranked 55 in the world, will be playing his fifth quarter-final of the season when he faces Argentina star Del Potro, who fought for just over three hours to win his opening match on Wednesday. Matosevic improved his record to 16-17 this season with his win over wildcard Thiem, who was the final chance for the host nation at the Stadthalle following the exit of two-time champion and fourth seed Jurgen Melzer. \"I played well against a tough opponent, he had the crowd on his side and I needed to concentrate,\" said Matosevic after his win over Thiem, the world 394. \"I\'m glad to win and am looking forward to a test against Del Potro. He\'s been serving unbelievably but I\'m ready for a tough match.\" Matosevic has already made a breakthrough this week, ending a six-match losing streak when he beat sixth-seeded Dutchman Robin Hasse in the opening round. Slovenia\'s Grega Zemlja shattered Australian hopes of seeing two players in the quarter-finals when he defeated Matthew Ebden 7-5, 6-4.
