Kleermaker saw off the likes of Aaron Turner, Dave Parletti and Nick Kenny en route.
The likes of Cody Harris, Jamie Caven and Wesley Harms were all involved so in reality it was a somewhat surprising win.
The ladies was also surprising with Hutchinson overcoming some big names to win the title.
Hutchinson overcame Aileen de Graaf followed by an in form Laura Turner.
There is one more tournament to take place in the West Fries Open on Sunday with the same amount of prize money to play for.
