The fancied names continued to fall on day two of the WGC-Accenture Match Play Championship as Luke Donald and Louis Oosthuizen were both well beaten.
Donald suffered a mauling at the hands of American Scott Piercy as he was thrashed 7&6, but there was better news for another Englishman, Ian Poulter, as he booked his place in the last 16.
To be fair to Donald there was little he could have done to stop Piercy who took just 30 shots to the turn, including holing out for eagle from 220 yards at the par-four fifth hole.
Oosthuizen, the last of the top seeds from the four brackets, saw his hopes ended by American Robert Garrigus who progressed with an impressive 3&2 triumph.
Poulter was on excellent form as he dispatched Bo Van Pelt to advance, the European Ryder Cup hero winning 3&1.
Poulter was actually seven-under-par for the 17 holes he played against his American opponent and will now face South Africa's Tim Clark in Saturday's third round after he beat Thorbjorn Olesen 3&2.
Lowry continues run
Shane Lowry followed his memorable victory over World No 1 Rory McIlroy with an even better display as he completely outplayed Sweden's Carl Pettersson to emerge a 6&5 victor.
Spain's Gonzalo Fernandez-Castano won by the same scoreline as he hammered Tiger Woods' conqueror Charles Howell III, but fellow Spaniards Sergio Garcia and Rafael Cabrera-Bello both bowed out as they were beaten by Matt Kuchar and Martin Kaymer respectively.
Belgian Nicolas Colsaerts - the defending Volvo Match Play champion - demonstrated his liking for the format as he knocked out Justin Rose with a 4&2 triumph.
Meanwhile, this week's defending champion also made comfortable progress as Hunter Mahan completed a convincing 4&3 win over Richard Sterne on the 15th green.
Four matches required extra holes with Jason Day beating Russell Henley at the 19th, Graeme McDowell finally shaking off Alex Noren at the 20th and Steve Stricker overcoming Nick Watney on the 21st hole.
The longest match of the day saw Bubba Watson edge out Jim Furyk on the 22nd green, while the final contest to finish saw Webb Simpson beat Sweden's Peter Hanson 1up with a birdie at the last.
Will Ian Poulter win a major in 2013?
