After failing to get in, Smith took full advantage and produced a 70 checkout to lead. Clayton levelled up but surged to the set after Clayton missed darts for it.
Clayton opened the second set with a 44 checkout but Smith made it 1-1. Clayton looked to potentially head towards sending it all the way with a 110 checkout for 2-2.
But Smith wasn’t in no mood to be sent through to a deciding set with a 130 checkout on double five producing clinically for ‘Smudger’.
Luke Humphries sealed the final spot in the second round and will now face Luke Woodhouse instead of recent nemesis Dave Chisnall after a straight sets win over Daryl Gurney.
It was another champion gone in Gurney with four 180's for 'Cool Hand Luke' en route.
Humphries wasn’t in any mood to give mercy in his opening gambit against Gurney. He produced two 180’s and after missed darts took the set on double eight 3-1.
Gurney went 2-1 up in the second set but a 130 set up from Humphries after not getting a shot at 170 saw the latter send it all the way. Gurney could only set up with a 139 to leave 32 and second time around, it was double 16 pinned for Humphries for the win.
