MASON, Ohio — Roger Federer jutted his right index finger toward the summer-blue sky to celebrate his latest Cincinnati title. He would have needed both hands to count all of them. Federer remained perfect in Cincinnati finals, winning an unprecedented seventh championship Sunday while denying Novak Djokovic the one title that always eludes him. Federer never faced a break point during a 7-6 (7-1), 6-3 victory at the Western & Southern Open. Serena Williams got her name on the Rookwood trophy for the second time, beating third-seeded Simona Halep 6-3, 7-6 (7-5) for back-to-back Cincinnati titles. She heads to the U.S. Open to try to become the first player since Steffi Graf in 1988 to pull off a calendar Grand Slam sweep. "I'm ready," Williams said. "I don't care if I win or lose or break even. I'm ready to start it, get it over with, and be done and go on to the next event. But I'm so ready for New York. Let's go, right?" It took Williams six tries to get her first Cincinnati title. Federer has never failed. The Swiss star is 7-0 in the finals. He loves the fast-playing courts and the small-town atmosphere in suburban Cincinnati heading into the big-city pressure of the U.S. Open. "I don't know how many years I can come back, but I'll try my best to be here many more years to come," Federer said.No surprise there."He's very good on this center court," Djokovic said. "He's more confident each year." By contrast, the world's top-ranked player is 0-5 in Cincinnati championship matches, never winning so much as one set. Djokovic covets the title, the only one he needs to become the first to win all nine of the current ATP Masters events. "The fifth time I've been in the title (match) and never won this title, so I guess I have to wait for Roger to retire," he said. "I've been coming back each year wanting it more." Federer feels for him. "I really hope you can win here someday," Federer told him on court during the trophy presentations. "He deserves it. C'mon, so close." In addition to Cincinnati, Federer has won seven titles at Dubai and Wimbledon and eight at Halle. With the win, he'll be seeded second behind Djokovic at the U.S. Open. Federer spent the past few weeks practicing in Switzerland, and he arrived in Cincinnati hoping to get his game smoothed out for the U.S. Open. His serve is right where he needs it. During his five matches in Cincinnati, Federer wasn't broken during 49 service games.
