Andy Murray kept on track to claim a record fifth title at Queen's Club by beating fellow Briton Aljaz Bedene 6-3, 6-4 to reach the quarterfinals Thursday. John Isner of the US fired 43 aces and held 10 match points but lost to Gilles Muller of Luxembourg 3-6, 7-6 (16), 7-6 (7). Murray faced a break point in the opening game but then broke to lead 5-3 and served out the set. Murray maintained the pressure in the second set, and despite failing to convert four break points to lead 1-0 and dropping his own serve after breaking for 2-1, a further break for 4-3 proved decisive. Murray's next opponent will be another countryman, Kyle Edmund, who received a walkover when Frenchman Paul-Henri Mathieu withdrew with a wrist injury. Isner seemed to be set for victory against Muller, holding six match points in the second-set tiebreaker, but Muller leveled the match on his fifth set point. In the final set, the American held off five break points as the set moved to another tiebreaker, but then failed to capitalize on a further four match points. Federer in quarters Roger Federer hurried into the quarterfinals of the Gerry Weber Open in Halle Thursday, wrapping up a 6-3, 7-5 victory over Tunisia's Malek Jaziri in 69 minutes. The top seed, who has won eight titles at the German grasscourt tournament that has proved ideal preparation for Wimbledon during his long career, quickly overcame a second-set hiccup when he dropped his serve to go 3-0 down. He rediscovered his rhythm, recovered the deficit and then broke the Tunisian in the 11th game before serving out the match. Federer next meets Belgian David Goffin, who was leading Sergiy Stakhovsky 4-6, 7-5, 2-0 when the Ukranian retired hurt after an awkward fall. The Swiss, ranked three in the world, is also joined in the quarterfinals by home favourite and eighth seed Philipp Kohlschreiber, who downed lofty Croatian Ivo Karlovic 6-7(7), 6-4, 7-5 despite being on the receiving end of 26 aces. Kvitova knocked out Petra Kvitova, the twice Wimbledon champion who has been hoping to build grass court momentum for a third title tilt, instead became the latest star to be eclipsed at the Aegon Classic Thursday. Moving gingerly on the lush surface, and crucially losing momentum after getting a break of serve early in the final set, Kvitova fell to a 6-4, 4-6, 6-3 second round loss to Jelena Ostapenko, the world No. 38 from Latvia. She next plays Madison Keys, the top 20 American who became the first player into the quarterfinals by winning 6-1, 6-3 against Tamira Paszek, the Austrian qualifier. Nadal set for Toronto return Rafael Nadal is on track to make the Olympics and plans to return from a wrist injury at the Toronto Masters at the end of July, days before the Games begin, his coach said Thursday. "The plan is to play in Toronto because that's what suits us," Toni Nadal, who is also Nadal's uncle, told a press conference in Mallorca, adding the 14-time Grand Slam title winner could start training on court again in two weeks. "It's following the normal recovery schedule and now he has to strengthen the wrist and the arm again," said Toni Nadal. "(Nadal) will arrive in form in Rio. It will give him time to prepare." Nadal had been scheduled to be Spain's flag-bearer at the opening ceremony. The Spanish federation announced earlier Thursday that Nadal and Garbine Muguruza will lead Spain's charge for Olympic tennis glory and could play together in the mixed doubles.
