Other leading lights in the field are Phil Mickelson, Padraig Harrington and Francesco Molinari.
2012 will be the last staging of the event under the banner of Barclays the British banking group responsible for the growth of the event to the status it now holds in the game.
The tournament has established such a position in the game however it is expected that other sponsors will follow although to have a sponsor with the deep pockets of Barclays may not be all that easy to come by.
In one of the more bizarre relationships in sport, the event is co sanctioned between the European and Asian Tours but is promoted by World Sports Group the promoters and global marketers of the OneAsia Tour which is in direct competition with the Asian Tour.
McIlroy will start the favourite not only because he is the game's number one player but because he has enjoyed three victories and one runner-up finish in four of his last six starts worldwide.
Adam Scott returned to competitive golf last week in Shenzhen and did well given it was his first tournament for five weeks. Scott has not won since August of 2011 but there have been plenty of good finishes plus he enjoys and amazing record in this event.
Scott has won the Singapore Open on three occasions and has been 3rd twice. The Sentosa Golf Club is clearly one that fits the eye of the Queenslander and following on from his 8th place finish last week in China.
Louis Oosthuizen won in Malaysia earlier in the year just a week after finishing runner-up at the Masters. The South African has been in good form again recently recording three top tens in his last three starts. Oosthuizen finished 3rd in this event last year so there is a lot to like about his chances.
Phil Mickelson finished runner-up last week in China and played the FedEx Cup series well. Mickelson has won only once in the last eighteen months but victory here would be of little surprise.
Given the co-sanctioning arrangement between the European and Asian Tours the Singapore Open offers the opportunity for a lot of Australians to gain a start in this lucrative event.
In addition to Adam Scott, Richard Green, Marcus Fraser, Andrew Dodt, Scott Hend, Kieran Pratt, David Gleeson, Darren Beck, Marcus Both, Rick Kulacz and Tim Stewart have starts.
Hend might be in for a lucrative week. He finished 3rd in this event three years ago securing one of his biggest cheques in the game. Hend has been in reasonable form of late.
