Rory McIlroy fully lived up to his top seeding at the WGC World Match Play championship in San Francisco on Saturday, crushing Asia's best Hideki Matsuyama 6&5 to reach the last eight.

The 25-year-old world number one only scraped into the last 16 at the death by coming back from two down with two to play to defeat Billy Horschel at the second extra hole of the closing round-robin games on Friday.

But there was no such jitters against Matsuyama who, like McIlroy, had won three straight to get to the tournament's knockout stages.

Both players birdied the par-five first before McIlroy holed from 25 feet for another birdie on the second to take the lead. A two-putt birdie from long range on the fifth was enough to take McIlroy two up.

Bogeys from a rattled Matsuyama at the sixth and seventh sent McIlroy racing clear at 4-up and the Northern Irishman birdied the eighth to go 5-up before Matsuyama finally grabbed some respite from the assault with a birdie two at the ninth.

But if the Japanese player harboured any hopes of staging an unlikely comeback they were all but snuffed out at the next hole when a rampant McIlroy chipped in for a winning birdie to restore a five-hole lead with eight to play.

Another birdie from McIlroy at the 12th made it mission impossible for Matsuyama and a one-sided contest came to an abrupt end two holes later leaving the Irishman still eyeing a quick detour to Las Vegas to take in the boxing showdown between Floyd Mayweather and Manny Pacquiao if he could finish his quarter-final in time.

"I'll need to play even better this afternoon to have a chance. There's two tickets and there's a plane waiting but whether I get on it or not we'll have to wait and see. But obviously this (the tournament) takes priority above anything else," said McIlroy.

In earlier last 16 results there were 2&1 wins for Gary Woodland over Australian Marc Leishman, for Australian John Senden over Hunter Mahan and for Englishman Tommy Fleetwood over South African Branden Grace.

Danny Willett pulled off an upset 3&2 win over countryman and former world number one Lee Westwood, who had put out Masters champion Jordan Spieth the previous day.

US veteran Jim Furyk was too good for JB Holmes, winning 5&3, while Rickie Fowler bounced back from an early deficit against South African Louis Oosthuizen to level the scores, but a poor approach to the 18th forced him to concede the tie.

Back-to-form Paul Casey made it three Englishmen in the last eight with a 3&1 triumph over South African Charl Schwartzel.
