With seven separate players having shared glory in the year's previous European Tour events, Aspinall became the first double winner of 2025 to scoop the £30,000 top prize. The Stockport ace had finally claimed a European Tour title at the European Darts Trophy in March, and leaves Leverkusen with another coveted trophy after denying Heta.
The Australian played his part in an epic final, hitting his first five attempts at doubles - but he crucially missed two darts to take the tie into a deciding 15th leg before Aspinall pounced for glory. Legs of 13 and 11 darts gave Aspinall the early edge, before Heta checked out 84, 130 and 140 - the latter finishes both completing 12-darters - as he edged ahead.
The Australian also took out 135 as the pair traded legs, before Aspinall punished misses from Heta to regain the edge at 6-5 and 7-6. Heta then missed his chance at double 18 to send the final into a deciding leg, and Aspinall returned to pin double six as he completed a brilliant triumph.
Aspinall, a Premier League semi-finalist had opened his challenge against Bradley Brooks on Saturday and ended German hopes in Leverkusen in Sunday afternoon's third round by seeing off Ricardo Pietreczko.
He then edged out Chris Dobey 6-5 in a tight quarter-final and averaged 103 in a gutsy semi-final win over Wessel Nijman which also went to a deciding leg.
