I'm a bit late to the game on this one, but I get to see the match with Barney leading 6-3 and Whitlock shooting 180 for his 3rd of the match to leave 121 but Barney steps up to finish 156 with perfect rhythm and precision to stretch the lead to 7-3
Whitlock throwing first and scoring just enough to hold his advantage, but Barney hits 140 leaving 141, Whitlock hits 180 to leave 70, but Barney steps up to take another cool finish... wants 141 hits t20, t19, d12.
In the two legs that I saw Barney was cool, relaxed and apparently enjoying himself.
Barney hits 4 - ton+ finishes... 116, 160, 156, and 141
Barney wins it 8-3
