Adrian Lewis is through to the second round of the World Matchplay but fellow Stokie Ian White is out.
Lewis who hit six 180s beat Steve Beaton 11-9.
He missed just eight darts at a double as he recorded his highest TV average in 18 months of 97.27.
Lewis opened up a two-leg advantage for the first time in the contest at 6-4.
The lead was maintained until Beaton, in his 21st World Matchplay appearance, struck a 111 checkout to level at 8-8, before successive holds of throw took the match to a tie-break.
A 104 finish saw Lewis hold throw before he took advantage of Beaton's low scoring in the following leg, booking his place in the last 16 with a 72 finish.
"It's a massive win for me," said Lewis. "Every time I did my job and got ahead of him I let him off the hook, but fair play to Steve he took his chances.
"I didn't get going at the Summer Series, but it was a good experience which put me in good stead for this tournament.
"I'm playing well enough, I'm showing glimpses but to win this tournament I know I've got to have my head on the whole way through.
"I've had to make a few slight adjustments because of my weight loss but I feel better for it.
"Danny [Noppert] has been playing well for the last 18 months, so that's another match I will have to be up for."
Ian White suffered heartache as he was beaten by Joe Cullen in a final leg decider 13-12.
Cullen avenged his 10-0 defeat to White in the 2019 event, coming through the first sudden-death leg of this year's tournament.
In a contest which saw both players struggling to produce their best, White was the more deadly finisher, landing checkouts of 151, 118 and 100 as he fought back from 3-0 down to take a commanding 8-4 lead.
The pendulum then swung back in Cullen's favour, as the Yorkshireman reeled off five successive legs, four of which were won in five visits to the board.
White found the bullseye for a crucial 89 finish to take the match to a tie-break, which saw Cullen hold throw before applying pressure to the his rival's throw on three occasions, only to see three match darts go begging.
With the players tied at 12-12, the contest went to a deciding leg, as Cullen took advantage of three treble-less visits from White before hitting the winning double at the sixth attempt.
"I felt great on the practice board and I genuinely thought I was going to blow Ian away, but that didn't happen when I got up there," admitted Cullen, who reached the quarter-finals in 2018.
"At 8-4 to me it could have been the same score to me, but I had to tighten up my loose darts.
"I've put a lot of work in since the Summer Series and it's all a learning curve but the target was to beat Ian because of what happened to me last year and I've managed to do that."
