"The putt was the worst one, I could see my hands physically shaking when I was taking the putter back so it was nice to hole it and a great way to win the tournament". He stands a good chance of winning this year's race by virtue of having amassed the most points.
The Sheffield man ripped up the rulebook to an extent a year ago in that he isn't a big hitter, whereas the previous winners all were.
While the PGA Tour Champions is catching flak for its playoff system, one that enabled Kevin Sutherland's sole victory to defeat Bernhard Langer's marvelous seven-win campaign, there won't be any controversy involved with the European Tour's Race to Dubai coronation this week.
In his teens, Sergio Garcia was seen as the next best golfer to come after Tiger Woods and the two even had fierce rivalry for some years.
"It would be the biggest moment of my career, I'll be well aware of that tomorrow", Jamieson said.
Rose will claim the title if he finishes first or solo second, and Fleetwood finishes third or lower.
It's all lush green rolling fairways, white sand bunkers (99 in total) and crystal-clear lakes (which patrol the last four holes in particular). I think they have narrowed a lot of the fairways from previous year. So you have to be careful with that because it's easy to forget.
On the three-way race for the Race to Dubai title, Garcia pleaded ignorance about the possibilities. "This is a place I've done well even before my win here last year - I finished fourth in 2015 - so I love the course and all being well I'll have a similar sort of result and end the year on a high". It doesn't really bother me.
"I can't control what other people do".
"To play the best I can play and give myself the best option of winning this week".
Justin Rose is the closest challenger to Tommy Fleetwood this week.
That said, Rose knows that another victory on the sprawling Earth Course would guarantee Race to Dubai success, which in itself would have a degree of symmetry to it. Obviously both Tommy and Justin are playing really well so I'm not expecting them to finish 40th or 50th. I can live with it.
Garcia finally broke his Major duck in 2017, but it shouldn't be forgotten that he got the year off to a great start by claiming the Dubai Desert Classic title and naturally there is a lot of crossover form between that one and this week's event.
Those poor souls have been subjected to the horrific ordeal of getting ready to play the season-ending DP World Tour Championship in 20-something degree heat while lapping up all that Dubai has to offer.
