PARIS — Spain's David Ferrer clinched his maiden Masters title when he ended Polish qualifier Jerzy Janowicz's brilliant run in Paris with a 6-4, 6-3 final win Sunday. Fourth seed Ferrer proved too consistent for world No. 69 Janowicz, who had previously beaten five players from the top 20. Janowicz gradually ran out of steam and Ferrer ended the contest on his first match point when the Pole sent a backhand wide. Ferrer, who fell down on the court in joy, heads to London where he will play in the World Tour Finals starting Monday. “I was very nervous because it was my chance to win a first Masters title but somehow I knew this time was my turn,” Ferrer told a courtside interviewer. Janowicz was probably mentally exhausted when he stepped onto the Berry center court, having already played seven matches en route to the final. “Again, I slept only four hours last night. I'm not a machine. I'm proud of myself,” the 21-year-old Pole said at court side. Janowicz, who started the year outside the top 200 and will break into the top 30 when the ATO releases its rankings Monday, had the first break point in the ninth game but wasted it by sending a forehand into the net. World No. 5 Ferrer took the opening set in the following game as Janowicz sent another forehand long. The Pole hit back in the third game of the second set, breaking for 2-1 when he successfully challenged a Ferrer forehand that was called in. The Spaniard, however, benefited again from Janowicz's unforced errors to break back in the following game. Janowicz continued to pressure his opponent but Ferrer had too much experience in the bag, pushing the Pole to misfire in long rallies to save another couple of break points. Ferrer now had his grip on the tie and he never released it, wrapping up a deserved win after one hour 27 minutes. Having bagged seven titles in 2012, Ferrer surpassed Roger Federer's tally of six, but the Spaniard played down the achievement ahead of the Tour Finals. Petrova trounces Wozniacki In Sofia, Russia's Nadia Petrova thrashed top-seeded Dane Caroline Wozniacki 6-2, 6-1 Sunday to secure her maiden Tournament of Champions trophy and a 13th career title. It was the 30-year-old's third tournament victory of the year after winning a Wimbledon warmup event in Den Bosch, the Netherlands, and the Pan Pacific Open in Tokyo in September. Winning the season-ending WTA event at the Armeets Arena in Sofia earned second seed Petrova a check for $270,000 and helped her rise one place in the world rankings to 12th. Federer to try to 1-up the rest at ATP finals The best tennis players in the world will be trying to one-up each other this week at the ATP Finals. Novak Djokovic has already clinched the year-end No. 1 ranking, robbing that aspect from the season-ending tournament for the top 8 players in the world. But with the Australian Open champion sharing the Grand Slams this year with Rafael Nadal (French Open), Roger Federer (Wimbledon) and Andy Murray (US Open), there is still one more big title to win in 2012. Federer said: “Whoever wins this wins something more. That's where I think you can feel the importance of this event.” Federer is in Group B with David Ferrer, Juan Martin del Potro and Janko Tipsarevic. Djokovic and Murray are in Group A with Tomas Berdych and Jo-Wilfried Tsonga. — Agencies
