Gary Anderson has defeated Raymond van Barneveld to secure his place in the last 16 of the Grand Slam of Darts.
The 2015 PDC world champion came through by a 5-3 scoreline to leave Van Barneveld needing to beat Larry Butler to join Anderson in the second round.
Andy Boulton had recorded three legs in a row to get back to 4-4 before American thrower Butler held his nerve in the final leg.
Phil Taylor is all but assured of a place in the next stage after averaging 108.42 on his way to a 5-2 win against Robbie Green.
Rowby-John Rodriguez kept his hopes alive with a 5-2 triumph against Martin Phillips, but he will likely need to beat Taylor in his final match.
James Wade impressed in his clash with fellow left-hander Mark Webster, averaging almost 106 on the way to an empathic 5-1 win, while 2014 quarter-finalist Keegan Brown prevailed from a last-leg decider against Michel van der Horst.
Robert Thornton is within touching distance of the second round after beating Johnny Clayton 5-2, while Terry Jenkins boosted his chances in a 5-0 whitewash of Geert De Vos.
