The US Open champion and world No 3 fired a bogey-free 65 to take a three stroke lead into the final round of a 30-man invitational offering appearance money for all, a $5m purse and a cool $2m for the winner.

He is also guaranteed a hug on the 18th green with women’s tennis No 1 Wozniacki expected to watch the final round action.

While he missed several putts, McIlroy still made seven birdies to lead by three shots from American Anthony Kim (65) on 18-under with Padraig Harrington 12 shots behind after a 73 saw him slip back to tied eighth.

Korean Noh Seung-Yul shot a 67 and lie in third on 14 under with Ian Poulter and Hunter Mahan seven adrift in fourth on 11 under.

Lee Westwood had just three birdies in a 70 and shares sixth with Australian Geoff Ogilvy on seven under.

Unsactioned by any tour and therefore bereft of world ranking points, the event has been criticised as a money grab for the elite and a vanity tournament that does little to grow the game in Asia.

According to agency reports:

Chinese property tycoon Shi Jian has stumped up the $5 million purse for the tournament and splashed out millions more on revamping the five-star 72-hole golf resort to major event standard.

The huge cash prize at the unsanctioned tournament has raised eyebrows in the golfing establishment — many critical.

McIlroy sought to defend critics waiting to pounce on elite players taking advantage of the boom in extravagant exhibition showcases in cash-rich China as the rest of the world tightens its belt.

“As golfers we are very fortunate to play for such large amounts of money. We all count ourselves as quite fortunate because of the way the world is at the moment, with a lot of people struggling,” he said.

The five-star resort features a tennis centre and the owner hopes to see Wozniacki make use of it during here stay.

“Caroline is arriving to cheer Rory on. We have readied the tennis centre at our golf resort because we’ve been told she likes to practise every day,” tournament owner Janson Shi told AFP.
