Rafael Nadal lost to fellow Spaniard Juan Carlos Ferrero 7-6 (2), 7-6 (3) in the quarterfinals on Friday, leaving the Western & Southern Financial Group Masters without its top two players. Top-ranked Roger Federer’s 55-match winning streak in North America ended on Wednesday with a loss to Britain’s Andy Murray.

Roger Federer was the only one who saw it coming: too much tennis, too little time off. The world’s top player knew it was the perfect combination for a long-awaited upset, one that a disbelieving British teenager pulled off on Wednesday. Andy Murray’s victory ended Federer’s 55-match winning streak in North America.

Roger Federer won his 22nd straight final on Sunday, beating Andy Roddick 6-3, 7-5 for the Cincinnati Masters title and his ninth overall victory this season. Federer improved to 10-1 against Roddick, who tried every tactic but still came up short. Federer has won the past six times they’ve met, including the past two Wimbledon finals.

Rafael Nadal’s 16-match winning streak ended when the 19-year-old Spaniard was beaten on Tuesday night in the first round of the Cincinnati Masters by a less-celebrated teenager. Tomas Berdych wore down the second-seeded Nadal in a two-hour, 57-minute match. Lleyton Hewitt played in his first match in the tournament.
