Dutchman confident he can cause an upset

Robin Haase is confident he has the game to test the best in the world when he faces Andy Murray in the second round of the US Open. The Dutchman has previously pushed the the likes of Andy Roddick, Lleyton Hewitt and Rafael Nadal hard at grand slams - with Haase leading the latter 2-1 at Wimbledon before finally losing in five sets. And Haase is hoping he can now build on these previous experiences. Haase said: "I've played Nadal, Hewitt, (Novak) Djokovic here, I'm used to the big courts. I'm looking forward to another one. Against Nadal I almost made it and now I hope I can do it." Haase beat Murray in their only previous meeting in Rotterdam in 2008 - and he is ready for the world No.4 at Flushing Meadows. "If you look at my results, I can beat almost anyone," he said. "I'll definitely have to keep my percentage of errors really low, because he's not making any errors most of the time. "I'll have to be healthy and be there mentally for every point. And of course I need to serve well. I just need to play my best game and hit a lot of winners."
