Cameron Menzies and Jesus Noguera are the top two players on the 2019 Unicorn Challenge Tour Order of Merit after 16 events.
Menzies and Noguera were joined by Callan Rydz and Patrick Lynskey in winning an event each last weekend in Wolverhampton.
With four events remaining (to be played across September 28-29 in Wigan), Scotland's Menzies and Spain's Noguera are in line to secure two-year PDC Tour Cards for the first time in their careers.
Following the conclusion of the 20th and final event, the player who tops the Order of Merit will book their place at Alexandra Palace for the 2019/20 William Hill World Darts Championship.
