Rory McIlroy thrashed Hideki Matsuyama 6&5 to progress to the quarter-finals with a victory that included four successive hole wins from the fifth tee.
Paul Casey and Tommy Fleetwood increased the British interest in the last eight with victories over Charl Schwartzel and Branden Grace respectively.
Elsewhere, John Senden defeated Hunter Mahan 2&1, with Gary Woodland despatching Marc Leishman by the same scoreline.
Former Open champion Louis Oosthuizen defeated Rickie Fowler by one hole and Jim Furyk made light work of JB Holmes, winning 5&3.
