Andy Murray overcame post-Olympic fatigue by winning his 21st straight match to reach the semifinals of the ATP-WTA Cincinnati Masters with a 6-4, 6-4 victory over Bernard Tomic Friday. Top seed Murray, running out of puff after claiming his second Olympic gold medal in Rio, grabbed his left hip in the opening game against Tomic, but soon settled in. The world No. 2 won his fifth match over the Australian and stands 32-1 since losing to Novak Djokovic in May in Madrid. "I knew that coming straight from the Olympics I was going to be tired. But I've still managed to win," Murray said. "Conditions help a bit. There are not a lot of long rallies. I have a few days off when this week is done and then I'll prepare for the US Open." Murray next faces fourth seed Canadian Milos Raonic, who beat Dominic Thiem 6-3, 6-4. The Scot leads the series 8-4, beating Raonic four times in 2016 including the Wimbledon final. Raonic advanced to his seventh semifinal of the season in 68 minutes. The 25-year-old finished with 32 winners, while Thiem, with four 2016 titles, managed only 10 winners and failed on two break point chances. "I definitely executed well. I did quite a few things well today," Raonic said. Former US Open champion Marin Cilic reached his first Masters semifinal, advancing when Croatian compatriot Borna Coric retired with fatigue after losing the opening set 6-2. Bulgarian Grigor Dimitrov put out new US No. 1 Steve Johnson in straight sets, 7-6 (10-8), 6-2. Dimitrov now faces Cilic, who has won two of their three matches. Women's Olympic silver medalist Angelique Kerber stands just two wins away from No. 1 after defeating Carla Suarez Navarro 4-6, 6-3, 6-0. Kerber could overhaul Serena Williams if she wins the title Sunday. "It all feels amazing, I'm seeing all the hard work of the last few years paying off," said Kerber, 28, who beat Williams in the final of the Australian Open but lost to her at the same stage at Wimbledon. "This is a moment for which I've been dreaming — and now I'm living the dream." Kerber will play 2015 finalist Simona Halep after the Romanian broke No. 5 Agnieszka Radwanska eight times in a 7-5, 6-1 win. Kerber needed a fightback against Suarez Navarro to post her 46th victory of the season. "It was not so easy to turn it all around in the second set. But I never doubted my game, I knew I could turn the match." Czech fifth seed Karolina Pliskova advanced over Russian seventh seed Svetlana Kuznetsova 6-3, 4-6, 6-2 and next plays fourth seed Garbine Muguruza, the French Open champion who beat Hungarian Timea Babos 6-4, 6-3.
