Viktor Troicki booked his place in the semi-finals of the Aegon Championships at Queen's Club with a straight-sets win over John Isner this evening.

Both players held serve throughout the opening set, but it was Troicki who held his nerve to win 7-5 in the tie-break.

Another tie-break seemed likely in the second set until Isner lost his serve in the eighth game to slip 5-3 behind.

Troicki then made no mistake to win the next game, and in turn the match, to clinch a spot in the last four.

The Serb will now face Andy Murray in the semi-finals, after the British number one's victory over Gilles Muller earlier today.
