hot run by dispatching surprise finalist John Isner 7-6, 6-3 Sunday to become the first player to win the Indian Wells ATP tournament four times. The Swiss world No. 3 blunted the powerful serving of Isner with a controlled display, edging the American 9-7 in the first set tiebreak then breaking him twice in the second set to triumph in one hour and 21 minutes. Federer clinched the title when the towering Isner, who upset world No. 1 Novak Djokovic in the semifinals and rose to a career-high 10th in the rankings, dumped a forehand into the net. The Swiss, who had won three consecutive titles at Indian Wells from 2004-06, raised both arms skywards in celebration as the capacity crowd at the Indian Wells Tennis Garden erupted in applause. “This tournament victory couldn't come at a better time in my career,” Federer, who has triumphed six times in his last eight ATP World Tour events, told reporters while sitting beside the glittering crystal trophy. Federer expressed a measure of surprise over his victory, having come close to withdrawing from the tournament before his opening match because of a lingering flu bug. On a cool afternoon in the California desert, the opening set went with serve until the 12th game when Federer, leading 6-5, had a chance to break Isner when the American hit a forehand long to go advantage down. However, the 6ft-9in (2.05m) Isner saved that with a 129mph (207km/h) serve to force a Federer error and the set went into a tiebreak where the Swiss squandered further set points when leading 6-5 and 7-6. Federer, beaten by Isner in four sets in a Davis Cup first round tie last month, finally clinched the set on his fourth opportunity when his opponent's backhand service return sailed long. He broke Isner in the seventh game of the second, unleashing a trademark backhand pass down the line to go 15-40 up before winning the next point when the American netted a backhand volley as he charged forward. After holding serve to lead 5-3, Federer broke Isner for a second time to end the match, improving his record for the year to 22-2 and surpassing Jimmy Connors and Michael Chang who were both three-time champions at Indian Wells. Since his semifinal loss to Djokovic at last year's US Open, the 16-time Grand Slam champion has been arguably the hottest player on the men's circuit, winning 39 of his 41 matches. Victoria Azarenka earlier routed Maria Sharapova 6-2, 6-3 for the women's title in the WTA Tour's first final between the No. 1 and No. 2 players since 2008. Federer and Azarenka each earned $1 million, the richest winner's checks in the tournament's history. The runner-up earned $500,000 each.
