NEW YORK - He's North America's top player but sadly for the success-starved United States, Milos Raonic is Canadian and wouldn't have it any other way. The 22-year-old Raonic stands at 11 in the world and is seeded 10 at the US Open where on Saturday he reached the fourth round for a second successive year. In contrast, John Isner is America's highest-ranked player at 17 in the world and carrying the burden of attempting to win his country's first Grand Slam men's singles title since Andy Roddick in New York in 2003. "Sort of the relief is definitely there that obviously there's a lot more pressure on Americans. I'm sort of doing a lot of stuff into unchartered territories so people are very supportive of it," said Raonic.–AFP
