Federer still committed to Davis Cup

Roger Federer insisted he remains dedicated to the Davis Cup despite his long-awaited comeback with Switzerland ending in a 3-0 humbling to the United States. After suffering a rare defeat to John Isner in Friday's singles, Federer slumped alongside Stanislas Wawrinka in Saturday's doubles against Mike Bryan and Mardy Fish in front of a partisan crowd in Fribourg. The Americans came from a set down to claim a 4-6, 6-3, 6-3, 6-3 win to complete the 3-0 victory for Jim Courier's men, who march on to the quarter-finals. "It was a tight match. Maybe our level dropped a tiny bit, just a game in each set made the difference," Federer said, according to AFP. The 16-time grand slam champion's defeat to the big-serving Isner snapped a 15-match winning streak in the competition. But Federer said he had no regrets at returning to first-round duty in the competition after an eight-year absence, and vowed to continue making himself available for his country. "I enjoy being with the guys," he said. "We will take it tie by tie. It's not a setback, or a step forward, it's nothing like that. I enjoy my time with the team and with [captain] Severin [Luthi]. That's what counts for me." Fish, who topped Wawrinka in an epic singles match Friday, was delighted to finish the job alongside doubles specialist Mike Bryan, whose usual partner, brother Bob Bryan, was away with his newborn daughter. "It feels great to win. I know what it's like to lose and that's not good," Fish said, according to AFP. "You always want to play with Mike, he's one of the best doubles players ever." Mike Bryan returned the compliment, saying, "It's fun to play with Mardy, he's a clutch player to come back after a four-hour singles on Friday and back it up. It's unbelievable."
