Phil Taylor completed back-to-back Players Championship victories in Nuland with a second successive win over Gary Anderson.
Taylor followed up his final-leg win over the Scot on Saturday in Holland with a 6-2 triumph in Sunday's decider, to claim the £6,000 title.
The win is Taylor's ninth on the PDC Pro Tour this year, and 11th in total in 2009, and takes his earnings to £232,000 since January 1.
Taylor led 2-0 in the final before Anderson took the third after six missed doubles from the world number one.
An 85 checkout put Taylor 3-1 up, and he followed a 177 with a 124 finish in moving three legs clear.
Anderson took leg six, but Taylor replied with an 11-darter that featured scores of 180 and 177, and sealed victory in 14 darts with an average of over 108.
Taylor had only lost five legs on his way to the final, recording 6-1 victories against Russell Mason, Julio Barbero, Andy Smith, Colin Osborne and Adrian Lewis.
Anderson's two finals over the weekend will almost certainly see him qualify for the Stan James World Matchplay this summer, as well as for the Ladbrokes.com World Darts Championship at the end of 2009.
He faced world number six Mervyn King in the first round, winning 6-2, before defeating former Lakeside champion Mark Webster in a deciding leg.
Steve Brown and Peter Wright were also defeated before he whitewashed Dutchman Vincent van der Voort in the quarter-finals and defeated Mark Walsh 6-4 at the last-four stage.
Walsh followed up his Players Championship win last weekend with a run to the semis, recording 6-5 victories against Larry Butler, Mensur Suljovic, Tony Eccles and Toon Greebe on the day.
Lewis' semi-final appearance was his first since he lost in two Players Championship finals to Taylor in Germany five weeks ago - although a 6-1 scoreline continued his losing run to his Stoke rival.
Vincent van der Voort hit his first competitive nine-darter two legs into the event, in a whitewash win over Mario Masurka, before going on to reach the quarter-finals.
Andy Jenkins was a quarter-finalist for the first time since January, while Dutch youngster Greebe made the last eight for the first time since October 2007.
