Joe Cullen edged ahead of Peter Wright in the race for a Premier League darts play-off place after winning week 15 in London.
Cullen beat Anderson, Wright and Jonny Clayton to move into fourth position in the table heading into the final week.
The win means Clayton and Wright will fight it out in Newcastle on Night 16 for the right to join Clayton, Michael Van Gerwen and James Wade in the final four.
Cullen started the night impressively, beating Anderson 6-1 before downing Wright by an identical score in the semi-finals.
On the other side of the draw, Premier League leader Clayton advanced to the final after coming through tough tests against Gerwyn Price and Michael Smith.
In the final, Cullen was able to sneak a 6-4 win to set up the showdown in Newcastle, where he will play Wright in a winner-take-all quarter-final clash.
"It is tough to play Jonny, he is a good friend of mine and I actually apologised to him for the reaction because I think it was a bit lucky with the shot at the end," Cullen said.
"It is not nice to celebrate like that against your friend and Jonny is a top lad but he knows how much I needed that tonight.
"I put so much pressure on myself the past few weeks and some of the performances have been horrific and I mean horrific.
"My B game is pretty good normally but it has been an A or a C, there has not been many B games in this Premier League and I have no issue in saying some of these performances, I was genuinely embarrassed.
"The performance in Dublin was embarrassing.
"I don't think I was great tonight but I ground the results out and, at the end there, it should have been a simple finish and it wasn't but that has been the story of the Premier League for me this year.
"You are trying to pick a game where you can guarantee two points and it is impossible.
"People will look at me and think I have got Joe [Cullen] tonight, that should be two points but we can all play really good darts on the night and I think that is testament to the PDC.
"The format this year is really cut-throat and the last four weeks I think I have lost in the opening round.
"I was under a lot of pressure tonight and I think, well I don't think, I know that I responded because I won the night."
