Peter 'Snakebite' Wright had an off night on the doubles and was subsequently beaten by Phil Taylor during the eighth round of Betway Premier League matches in Manchester on Thursday.
Mendham darts ace Wright was superior in virtually every other department, with an average of 102.45 to Taylor's 98.75.
Wright also hit six 180s compared to the 16-time world champion's five, but ultimately it was the 12 missed doubles that cost the Scot the match and his place at the top of the table.
The score was level at three legs apiece when Wright's finishing issues rose to the surface.
Taylor pounced by racking up the next three legs to guarantee himself at least a point and while Wright threatened a dramatic late comeback - which included a 156 checkout to keep his hopes alive - the match ended 7-5 in The Power's favour.
Speaking afterwards, the victorious Taylor said: "It's a massive win for me. It was a strange game - we've both missed plenty of doubles, but his 156 was incredible and I thought he was going to come back and get a draw.
"He seems to do things under pressure like Michael van Gerwen does, he's a brilliant player and I think he's going to get stronger, but on the night he wasn't as good as he normally is."
Wright is now second in the standings as the tournament heads to Cardiff next Thursday, with world number one Michael van Gerwen leading the way by a point.
Already-eliminated Kim Huybrechts will provide the opposition for Wright in the Welsh capital.
Meanwhile, number two seed Wright will take on either Michael Plooy or Christian Kist in the second round of this weekend's HappyBet German Darts Championship in Hindesheim.
