Stuart Grehan earned 65 World Amateur Golf Ranking points for his victory in the South of Ireland at Lahinch — more than double Stuart Bleakley's bounty for his win in 2014.
An improved field last week helped the event move from Category F to D, meaning it is now back on a par with the other three provincial championships; the East, the West and the North.
Grehan's second provincial "major" win of the season also helped him jump 69 spots on the World Amateur Golf Ranking to 269th and earn his first senior international cap.
The other main Irish movers his week are Irish No 1 Cormac Sharvin, who rose one spot to 14th in the world, Gary Hurley up two to 25th, Paul McBride up 14 to 417th, Kevin LeBlanc up eight at 484th and Alex Gleeson, up 131 places to 493rd thanks to his victory in the Boyd Quaich at St Andrews.
In the women's rankings, Duke's Leona Maguire remained at No 1 with Olivia Mehaffey up four places to 31st following the European Ladies' Amateur Championship. Castletroy's Chloe Ryan also moved into the top 200 at 196th thanks to a 22 place rise.
