Unlike those other fellows, he's still in the game -- ranked No. 3 coming out of Toronto. In fact, Federer was the only member of the Big Four to reach the semifinals, with Rafael Nadal sidelined with a wrist injury and Novak Djokovic and Andy Murray losing to Jo-Wilfried Tsonga.
Federer lost in the final, giving Tsonga a week to remember; he beat four top 10 players -- in four days.
Heading into Cincinnati, where are the big names in men's tennis trending? Let's go to this week's Up or Down.
No. 1 Novak Djokovic: Just when it looked like the Wimbledon champion was ready to tear into the hard-court season, he was upended by Tsonga, the No. 13 seed. Maybe he was just saving some tread on his tires for the push to the US Open ... or was it something more?
No. 3 Roger Federer: He turned 33 last Friday in Toronto, but Federer's still got staying power. He got by Marin Cilic in a fabulous third-round match that featured some vintage shots. And what about that casual between-the-legs shot against Feliciano Lopez in the semifinals? That tells you all you need to know about his mindset entering Cincinnati.
No. 4 Stan Wawrinka: Since winning his first Grand Slam singles title at the Australian Open and his maiden ATP Masters 1000 in Monte Carlo, the Swiss No. 2 has had some issues regaining his footing. Wawrinka lost his second match in Toronto to Kevin Anderson and is a spotty 9-6 since Monte Carlo.
No. 6 David Ferrer: The Spaniard is 32 now, but still good enough to reach the quarterfinals in Masters 1000 events. He beat Michael Russell and Ivan Dodig to get there in Toronto, falling to Federer in three sets. He remains a top-10 player and will be among the top eight seeds at the US Open.
No. 7 Milos Raonic: The Washington champion ran out of steam at home in Canada, losing a three-set quarterfinals match to Feliciano Lopez. He had nine break-point opportunities in an early game in the third set but failed to convert. Like compatriot Eugenie Bouchard, Raonic may benefit from playing this week in an arena that doesn't harbor huge expectations.
No. 8 Grigor Dimitrov: The 23-year-old Bulgarian continues to impress. He won his first three matches in Toronto (beating hard-serving Kevin Anderson in the quarters) before running into a red-hot Tsonga. Going forward, it will be interesting to see how Dimitrov deals with the new pressure of being a top-10 player.
No. 9 Andy Murray: Murray had won nine of 10 previous matches against Jo-Wilfried, but couldn't get past the Frenchman in the quarters. The year after he underwent back surgery, Murray has yet to win a title. He has a chance to turn around his season in Cincinnati and New York.
No. 10 Jo-Wilfried Tsonga: Tsonga entered Toronto as the No. 15-ranked player among ATP World Tour players and had gone out in the fourth round of the three Grand Slams (losing to Federer and Djokovic twice). He was a revelation in Canada, knocking off Djokovic, Murray, Dimitrov and Federer on the way to a memorable title.
