MASON, Ohio — Roger Federer and Andy Murray advanced to the semifinals of the Western & Southern Open in contrasting fashion Friday to set up a rematch of their Wimbledon clash. Federer made quick work of Spaniard Feliciano Lopez in a 6-3, 6-4 quarterfinal romp that lasted just over an hour. Murray needed to grind out another win against Richard Gasquet, outlasting the Frenchman 4-6, 6-1, 6-4 after two hours. Third seed Murray saved a match point in the third set and fought fatigue to win his second straight three-set battle. “I fought and gave everything I had, but thankfully it's just been enough in the last two days,” Murray, who lost to Federer in straight sets in the Wimbledon semifinals, told reporters. Earlier, top seed Novak Djokovic avenged his French Open final loss to Stan Wawrinka by crushing the Swiss 6-4, 6-1. Djokovic, now two wins away from becoming the first player to win all nine ATP Masters titles, needed a mere 63 minutes to dispatch fifth seed Wawrinka in the first meeting between the players since Roland Garros. Wawrinka denied Djokovic a chance to complete a career Grand Slam in Paris but was wayward in Cincinnati, finishing with 33 unforced errors and pushing a backhand wide on match point. Djokovic, a four-time runner-up in Cincinnati, broke Wawrinka's serve four times and dropped just 12 points on serve in his final tune-up event ahead of the US Open which starts Aug. 31. “(My performance) came at the right time against one of my biggest rivals and the guy I lost to last time we played in the finals of the French Open,” Djokovic said. “Obviously I approached this match very seriously in trying to prepare myself and get myself in a good position to win.” The world No. 1 next faces Ukrainian qualifier Alexandr Dolgopolov, a 6-4 6-2 winner over Czech sixth seed Tomas Berdych. In the women's section, defending champion Serena Williams reached the semifinals but not before having her mettle tested in a 3-6, 6-4, 6-2 win over sixth-seeded Serb Ana Ivanovic. Williams, who will be chasing a calendar sweep of the four grand slams at the Aug. 31-Sept. 13 US Open, struggled with her serve and was forced to come from behind several times in a rematch of last year's final. “Out of the previous nine times we've played I think we've gone three sets at least six times so I know she plays really well,” the top-seeded American said in an on-court interview. “She's been No. 1, she's won a Grand Slam. I knew it was going to be a big test for me today and I'm really happy I was able to get through.” Up next for Williams will be 14th-seeded Ukrainian Elina Svitolina, a 6-4, 2-6, 6-0 winner over Czech Lucie Safarova, seeded seven. In the other quarterfinals, third-seeded Romanian Simona Halep dispatched Russian Anastasia Pavlyuchenkova 7-6, 6-2. She will now face a semifinal against Serbian Jelena Jankovic who beat Slovakian qualifier Anna Karolina Schmiedlova 6-4, 6-2.
