Smith dumped out Michael van Gerwen in a stunning 6-5 win which saw him take out 114 to claim the victory and further increase the likelihood of a new winner.
'Smudger' in the early going moved 2-1 in front averaging around 105 but this dwarfed to MVG's 119 average but despite that at the break it was 3-2 with Smith missing one dart to take the lead himself.
When they returned though, he hit the front again landing a fifth 180 to go 4-3 ahead. MVG responded in kind with an 11 darter to make it 4-4 and they exchanged legs before Van Gerwen forced a decider.
After a tense couple of visits, Smith brought himself down to a finish and didn't make no mistake pinning the 114 for victory which seemed to massively shock the Deal ace.
Gurney also had to claim a hard fought win seeing off William O'Connor averaging 98 and hitting five 180's in defeating 'The Magpie'.
'Superchin' was excellent in the early going going 4-1 up at the interval with 4/7 on the doubles as it looked like he was cruising.
That wasn't the full story though and O'Connor took successive legs to go only 4-3 down in a matter of time but despite that Gurney missed match darts which in this case allowed O'Connor a second chance as he went only one behind at 5-4.
Gurney didn't miss his second opportunity though confirming his place in the second round and averting a similar shock to Van Gerwen.
