Come the end of tonight, a new Premier League Darts champion will be crowned at London's O2 Arena.
It all started with eight players back in February, but now only four remain with their sights set on winning one of the biggest tournaments in the world of darts.
Defending champion Michael van Gerwen is making his tenth appearance in the play-offs and will be looking to make successful defence of his title.
Tonight's event will be kicked off by the all-Welsh battle between table-topper Gerwyn Price, and Jonny Clayton, and then followed by a rematch of this year's World Championship final when Van Gerwen and Michael Smith go head-to-head. The winner of these two semi-finals will meet in the final.
