Stanislas Wawrinka has eased his way into the quarter-finals of the Aegon Championships at Queen's following a 6-2 6-2 victory over Sam Querrey.

The Australian Open champion grabbed the first break of the match and immediately held to take a 4-2 lead. A further break was enough for Wawrinka to push on and ease to a one-set lead in London.

Despite Querrey saving three initial break points, Wawrinka once again was able to see it through and break his opponent's serve in the second set.

Wawrinka continued to dominate on the grass surface by securing another break point to ease his way to victory.
