Defending champion Grigor Dimitrov has been beaten in the second round of the Aegon Championships at Queen's Club by Luxembourg's Gilles Muller.
The world number 48 produced a powerful serving display to knock out the sixth seed on centre court and reach the quarter-finals.
In the first set, Muller had to save three break points in the third game of the match, and it looked like a tie-break would be needed with both men confident on serve.
However, Muller snatched it 6-4 as Dimitrov wobbled in the 10th game with a double-fault and loose forehand.
The second set did go to a tie-break and Dimitrov was the first to move ahead as he won three points in a row at the start of the breaker.
Muller hit straight back and the pair changed ends at 3-3 before the Luxembourger produced a forehand winner down the line to move ahead, serving it out 7-5 for victory.
He will next face the winner of this afternoon's match between top seed Andy Murray and Spain's Fernando Verdasco.
