(CNN) -- Tournament favourite Andy Murray is through to the quarterfinals of the AEGON Championship at Queen's Club in London after a straight sets victory over Guillermo Garcia-Lopez of Spain.
Top seed Murray continues to look strong as he secured a place in the quarterfinals at Queen's Club.
The top seed's 6-4 6-4 victory, achieved in just under 70 minutes, sets up a last-eight clash against American Mardy Fish.
"Once I got the break in the first set, I felt more comfortable and went for my shots a bit more," world number three Murray told reporters after his victory on Thursday.
Eighth seed Fish booked his place in the quarterfinals with a 6-1 6-4 success over Spain's Feliciano Lopez, the 10th seed.
Veteran clay-court specialist Juan Carlos Ferrero also secured his place with a 6-4 7-6 win over Belgian Xavier Malisse.
He now faces Steve Darcis in the quarters, after fourth seed Gael Monfils was forced to withdraw from their all-French encounter with a wrist injury.
Sixth seed James Blake also progressed, but the American was made to battle before defeating compatriot Sam Querrey 6-4 4-6 6-3.
American second seed Andy Roddick won the battle of the two multiple Queen's winners, when he beat Australian Lleyton Hewitt 7-6 7-6.
Roddick and Hewitt have won the pre-Wimbledon warm-up event eight times between them, with Rafael Nadal's victory last year the first time neither player had lifted the trophy this decade.
But Hewitt's bid for a record fifth success in west London is over for another year after Roddick edged through to the quarterfinals, where he will face Ivo Karlovic, whom he beat in the 2005 final.
Meanwhile, in the Halle grass-court tournament in Germany, second seed Novak Djokovic -- the tournament favorite after Roger Federer's withdrawal -- had to fight back from dropping the opening set to defeat Florent Serra of France 5-7 7-5 6-1.
The Serb was joined in the last eight by seventh seed Jurgen Melzer of Germany, who progressed when local favorite Nicholas Kiefer retired after losing the opening set 6-1.
