Brett Rumford has moved up to sixth in the Race to Dubai Standings after the Perth International.
The Australian finished sixth at the latest event on the European Tour at Lake Karrinyup Country Club in Western Australia.
The top five in the rankings, Henrik Stenson, Graeme McDowell, Justin Rose, Richard Sterne and Matteo Manassero, were not in action this week.
Jin Jeong beat Ross Fisher in a playoff to take the tournament victory, his first on the European Tour as reported by the organisers' official website.
England's Fisher can take some small consolation by moving into 43rd in the Standings with 576,427 points, according to the updated list published by the European Tour.
Fisher was quoted by ESPN as saying he thought he had done enough to qualify for next week's BMW Masters in Shanghai: "Hats off to Jin for winning his first professional tournament. I'm just pleased I'm knocking on the door and I know one of these days, it will come. I've moved up in the Race to Dubai I should hope that's got me into next week in China."
That event kicks off the Final Series—four events that culminate in the DP World Tour Championship, where the Race to Dubai will be settled on November 17.
With the tour citing a cumulative prize fund of $30.5 million for the Final Series, there are plenty of chances for the final rankings to be shaken up. Stenson is looking nervously over his shoulder at a confident McDowell in particular.
