The 2023 champion averaged 108.55, hit seven 180s and had a checkout percentage of 76.9% as he won 10-3 in Wolverhampton.
His quarter-final opponent will be Michael Smith, who beat Chris Dobey 10-9 in a dramatic encounter.
Smith was 5-2 down but levelled at 5-5 with a 164 finish, before he went on to take a 9-8 lead.
Dobey made it 9-9 to set up a decider, but missed 11 match darts as the tension seemed to get to both players, prior to Smith eventually securing victory.
