Roger Federer reckons that it wouldn't take much to prevent him from winning his second straight U.S. Open title. A virus. An injury. A windy day that makes everything go awry. ``A little thing needs to go wrong and you lose,'' he said. For everyone else, maybe. It's going to take a whole lot more to keep the Swiss star from extending one of the most dominant runs in ATP history.
