Scott who led after his opening round of 62, took a while to get going today but once he did he was all but unstoppable, only a three putt bogey at the last keeping him from an even greater lead.
And all of this with a flu like complaint earlier in the week.
Scott has shown over much of his career that he is a noted front runner, and although there have been exceptions such as the Open Championship in 2012 and last year's Australian Open, once he has the lead he has often proven hard to run down.
He will get his chance once again over the closing 36 holes to not only win a 10th official PGA Tour title but to close within a breath of Tiger Woods' mantle as the games leading player (statistically at least).
Scott is playing the event for the first time since 2009, a run of poor results causing him to leave it off his schedule until this year. He does however feel more comfortable on a layout which has undergone change since he missed the cut the last time he played the event.
J.B Holmes is playing on a medical exemption this year after injuring himself roller-blading last year and needs to earn US$$580,000 in 19 events this season.
Hadley won recently in Puerto Rico in his rookie PGA Tour season after a great year on the Web.Com Tour last season.
Aaron Baddeley is the next best of the Australians in a share of 16th place albeit tens shots from Scott's lead.
