Andy Murray to face Milos Raonic in Cincinnati Masters semi-final
Britain's Olympic champion Andy Murray beat Australia's Bernard Tomic 6-4 6-4 to reach the Cincinnati Masters semi-finals.
The world number two will now face Canadian fourth seed Milos Raonic, who he beat in the Wimbledon final in July.
The Scot, who served 10 aces, will attempt to stretch his career-best winning streak to 22 matches.
"I knew that coming straight from the Olympics I was going to be tired but I've still managed to win," he said.
"I played the big points well and that was the difference. That comes from winning big matches and making better decisions."
In the other semi-final Croatian 12th seed Marin Cilic will face unseeded Bulgarian Grigor Dimitrov.
Jamie Murray and Brazil's Bruno Soares were beaten 4-6 6-2 11-9 in the doubles quarter-finals by Dutchman Jean-Julien Roger and Horio Tecau of Romania.
In the women's draw, Germany's Angelique Kerber remains on course to overtake Serena Williams at the top of the rankings after beating Spain's Carla Suarez Navarro 4-6 6-3 6-0.
Kerber will play third seed Simona Halep in the semi-finals, knowing that if she takes the title in Cincinnati she will end Williams' 183-week reign as world number one.
"Of course, everybody is asking me this question," said Kerber.
"When the time is ready, maybe I can reach number one Still, it's a long way. It's closer than a few days ago when I sat here."
