Andy Murray has sealed his place in the semi-finals of the Miami Open after defeating world number 38 Dominic Thiem.

The British no. 1, who reached the quarter-final stage of the competition after sealing his 500th career ATP tour win over Kevin Anderson on 31 March, lost the opening set but recovered well to seal a 3-6 6-4 6-1 win.

Murray will now meet Tomas Berdych in the semi-final stage as he targets a fourth final in Miami.

The 27-year-old rallied after a disappointing opening set and capitalised on a series of unforced errors against his Austrian opponent in the second. Thiem managed to claw the contest back to 4-4 before Murray broke again.

Having levelled the contest, Murray dropped just one game in the deciding set to ease to victory.

"I expected a tough match," Murray said. "He's beaten some very good players this week already. When you let him dictate the points, he hits the ball as hard off each side as anyone.

"I think in the third set the difference was really my returning. I returned his first serve extremely well. I put him on the back foot. When I was returning the first serve well, I was able to dictate points."
