Nijman has been superb all day and has averaged between 92 and 96 for most of the day going from strength to strength after easing past Raymond van Barneveld 5-1 in his opener.
He ended the day by doing the same and averaged 96 in the process with four 180's in defeating the former Lakeside World Champion.
This was also book ended with victories over David Evans and Paul Nicholson 5-4 and 5-3 respectively.
Speaking of Evans, he also ended the day superbly defeating Nicholson 5-2 to make it three wins out of four as 'Stretch' finished second on Day One.
For most of the day, he has capitalised in some cases on players not kicking on and this was the case against 'The Asset' with a timely break after the latter missed a dart at double 16 and followed that up with a hold of throw brought him on the way to victory.
