Andy Murray overcame a stiff challenge from Janko Tipsarevic to reach the quarter-finals of the AEGON Championships.
The British number one had his serve broken in the first game of each set, but recovered with aggressive tennis to beat the Serbian 14th seed 6-4 7-6 (7-3).
“It was a high-quality match. We both played well, especially at the end of the second set. It was a big test,” said Murray.
Murray had questioned whether he should be playing at Queen’s Club this week after damaging his right ankle en route to the French Open semi-finals.
But Wimbledon starts in less than a fortnight and Murray also needs time on grass courts in order to adapt properly from the clay at Roland Garros.
Rafael Nadal and Andy Roddick also made into the last eight, with wins over Radek Stepanek and Kevin Anderson respectively.
