Andy Murray beaten by Roger Federer in Cincinnati
Andy Murray was beaten 6-3 7-5 by world number three Roger Federer in the quarter-finals of the Western & Southern Open in Cincinnati.
After losing the first set, Murray, 27, fought back to lead 4-1 in the second, but lost six of the final seven games.
Federer, 33, now faces Canadian Milos Raonic in a re-match of their semi-final meeting at Wimbledon in July.
"I don't remember hitting very many good shots after the 4-1 game. I blew it, it's a shame," said Murray.
Federer dominated from the start and forced Murray to save six break points before making the decisive break in the fifth game.
A series of Murray forehand winners gave him a double-break 4-1 lead in the second set, but he lost three of his next four service games as Federer rediscovered his first-set form.
Murray has not won an ATP ranking event or beaten a top-10 player since Wimbledon in 2013 and since having surgery on a back injury last September his ATP world ranking has slipped from third to ninth.

"The court is like a battlefield. It's my job. It's where I'm supposed to perform."
