LONDON -- Andy Murray reached the quarterfinals at Queen's Club on Thursday after overcoming Nicolas Mahut 6-3, 7-6 (4) in a match suspended overnight and then beating Australia's Marinko Matosevic 6-2, 6-2.
Defending champion and No. 5 seed Marin Cilic of Croatia saved a match point and swept the last five games to defeat Spanish qualifier Feliciano Lopez 4-6, 7-6 (5) 7-5.
There were also wins for second seeded Czech Tomas Berdych, No. 3 Juan Martin del Potro of Argentina and fourth-seeded Frenchman Jo-Wilfried Tsonga. But the No. 6 and 2010 champion Sam Querrey was upset by former four-time tournament winner Lleyton Hewitt, who came through 5-7, 6-3, 6-4.
Murray resumed his match against Mahut at 2-2 in the second set and fought off three break points in his first two service games before claiming victory in the tiebreaker.
The top-seeded Scot then took early charge against Matosevic, breaking to lead 2-1 and again in the fifth game. A break for 1-0 gave Murray a perfect start to the second set and a further break for 4-1 all but sealed his opponent's fate.
"The hardest part is just the waiting around," Murray said. "We came off maybe three times yesterday. Today, the same thing again, a lot of waiting around for my match this afternoon. It's important to make sure you sort of relax and don't waste too much energy between matches."
Berdych eased past 16th seeded Slovenian Grega Zemlja 6-3, 6-4, and Del Potro surrendered just eight points in the opening set against Britain's Daniel Evans before winning 6-0, 6-3.
Tsonga, who finished as runner-up to Murray in 2011, survived two three-set battles, defeating fellow Frenchman Edouard Roger-Vasselin 6-3, 6-7 (2), 6-3 in a rain-delayed second round match and then Dutchman Igor Sijsling 7-5, 5-7, 6-3.
American Denis Kudla reached his first ATP Tour quarterfinal with a 6-1, 6-3 win over Kenny De Schepper of France, and Germany's Benjamin Becker upset No. 7 seed Alexandr Dolgopolov of Ukraine 7-6 (5), 7-5.
