Third-seed Andy Murray recovered from an early setback to beat Austrian Dominic Thiem 3-6, 6-4, 6-1 on Wednesday to reach the semi-finals of the Miami Open where he will face Czech Tomas Berdych.

Murray's 501st career win was far from easy as the 21-year-old Thiem, ranked 52nd in the world, used an impressive backhand and some entertaining tennis to take the first set.

But after Murray, far from his best, forced a deciding set, he took firm control after earning a break at the end of a long fourth game to go up 3-1.

Eighth seed Berdych defeated Argentine Juan Monaco 6-3, 6-4 in their quarter-final to set up a re-match of their tense and at times acrimonious Australian Open semi-final which Murray won in four sets.

Monaco, backed by a large Argentine support, put up a strong fight in the second set until Berdych broke for a 5-4 lead.
