Michael van Gerwen landed the PDC European Tour's first nine-dart finish for five years with a stunning perfect leg against Ryan Joyce in Hamburg on Saturday night.
Van Gerwen began his bid to win a sixth European Tour event of 2018 with a 6-2 win over qualifier Ryan Joyce, which will go down in history for the Dutchman's moment of perfection.
The world number one led 2-1 before opening leg four with scores of 180 and 177, and then took out 144 with two treble 20s and double 12 to secure a nine-dart finish.
Van Gerwen later took out 121 as he went on to seal a 6-2 win and a place in Sunday's final stages.
The last nine-darter on the European Tour had been achieved five years and a day earlier by Ross Smith in the Gibraltar Darts Trophy, with a host of players - including Van Gerwen - going close to perfection in the intervening years.
