Daryl Gurney completed a Premier League double over Michael van Gerwen with an 8-5 triumph in their Manchester contest on night 14.
The Derry man raced into a four-leg lead, taking out 105 and 76 for breaks of throw, before a 127 checkout from Van Gerwen got the reigning champion off the mark.
Double eight saw Van Gerwen take a second leg before Gurney restored his four-leg cushion, and even a 130 checkout from the Dutchman was unable to stop his rival securing at least a draw at 7-4.
Van Gerwen finished 100 to keep his hopes alive in leg 12, but tops for Gurney sealed a key win as he stays a point away from the top four.
"Michael's the best player in the world so it means a lot to me to beat him again," said Gurney. "To beat him twice in one season is a nice record to have.
"I don't panic any more against him now, where I maybe tried too hard to beat him in recent years. I needed to get something out of the game and luckily I came away with the two points.
"If I can go into my next two games with the same temperament I could win them, and if I can get into the top four I will be very happy."

'The Machine' never looked like surrendering the lead after moving 3-0 up, with Price opting not to shake hands before walking off the oche at the end.
Mensur Suljovic occupies the final play-off spot following an 8-6 triumph over struggling Peter Wright, who is winless in nine matches.
The 47-year-old started with a 144 checkout and, despite leading 3-0 and 5-1, was forced to hold off a late fightback to claim his eighth win in his last nine games against Wright.
