Dave Chisnall sealed his place in the Betway Premier League play-offs with a 7-4 win over Adrian Lewis in Birmingham on Thursday night.
The Morecambe ace, who consolidated second place in the table, has two league nights left to play but can now look forward to being part of the final four at The O2 in London on May 21.
Lewis opened the game with a 180 and led 3-1 before Chisnall turned the contest on its head with successive checkouts of 130, 116 and 104, before taking out a key 61 to move 5-2 up.
He added a 180 to lead 6-3, and though Lewis hit back in the next it was the 2014 Grand Slam of Darts runner-up who claimed the win.
Chisnall said: “I’m delighted.
“I’ve finished well this season and that was the difference again tonight.
Even though I’m through it’s important to keep playing the darts I’ve been playing recently - you don’t want to slack off and hopefully I can carry on winningDave Chisnall
“The defeat last week (to Raymond van Barneveld) was playing on my mind a bit before the game and I started slowly, but those three ton-plus finishes probably won me the game.
“Adrian missed a few darts at a double and I took my chances and scraped the win.
“Even though I’m through it’s important to keep playing the darts I’ve been playing recently - you don’t want to slack off and hopefully I can carry on winning.”
Elsehwere, Van Barneveld jumped up to third in the table with wins over Lewis and Gary Anderson at the Barclaycard Arena.
Phil Taylor is in danger of missing out on the Play-Offs for the first time since the Premier League was introduced in 2005 after a 7-4 defeat to Michael van Gerwen.
The night’s other game saw James Wade and Stephen Bunting share a dramatic 6-6 draw which means that the duo cannot now qualify for the Play-Offs.
The two remaining league nights, at the Metro Radio Arena in Newcastle next Thursday and at The Brighton Centre on May 14, will see four games played per night as the battle for the final two Play-Off places concludes.
Chisnall next takes on Bunting in Newcastle but first has three Players’ Championship events in Coventry on Friday, Saturday and Sunday.
