STAN THE MAN: Wawrinka has lost 13 of 15 career matches against Federer, but 14 of those encounters came before the player who wears T-shirts saying "Stan the Man" won his first Grand Slam title at the Australian Open in January. In their most recent matchup, in the final of the Monte Carlo Masters on clay in April, Wawrinka won. "It's going to give me a lot of confidence about myself, knowing that I can beat him," Wawrinka said. "Doesn't matter where." They've been pals for years and paired up to win a gold medal in doubles for Switzerland at the 2008 Beijing Olympics.
