Ryan Meikle made it two PDC Unicorn Development Tour title wins in as many days in Hildesheim on Sunday, while Wessel Nijman was also victorious.
Having claimed the fifth Development Tour title of his career at Event Two on Saturday, Meikle made it back-to-back triumphs in Sunday's opening event.
The 23-year-old averaged 97.8 in his 5-2 semi-final win over Sebastian Bialecki, before winning 5-3 in the final against emerging German talent Nico Kurz.
The opening Development Tour weekend of the year concluded with Dutchman Nijman doubling his career tally of titles.
Having competed on the Unicorn and Challenge Tour systems since 2017, Nijman enjoyed his first taste of ProTour action in 2019 and he continued his progress with a 5-3 win over established German talent Martin Schindler in the final.
