Stanislas Wawrinka and Richard Gasquet wasted little time in reaching the quarter-finals of the Estoril Open in Portugal.
Second seed Gasquet was particularly impressive, losing only two games in his 6-1 6-1 victory over Paolo Lorenzi, while third seed Wawrinka had a trickier time in the first set against qualifier Ivan Navarro before coming through 7-6 (7/5) 6-1.
The Swiss blew four set points in the first-set tie-break but eventually clinched it at the fifth attempt.
In the last eight Wawrinka will face Dutch sixth seed Robin Haase, who dropped the opening set to another qualifier, Inigo Cervantes, but recovered to win 5-7 6-4 6-2.
Awaiting Frenchman Gasquet is Spanish qualifier Daniel Munoz-De La Nava following his 6-4 6-4 victory over eighth seed Flavio Cipolla, while in the final first-round match America's Bobby Reynolds beat Attila Balazs, of Hungary, 6-3 6-4.
