Victory was also payback for Humphries after he lost last year’s final to Littler as their rivalry continues to grow.
Since first playing each other in the 2024 World Championship final, the pair have faced off a further 22 times with Littler claiming 13 wins to Humphries’ 10.
They are the two top-ranked players in the world and over the past 18 months, that has been abundantly clear.
When they are on top form, it feels as if the other is the only player who can live with them.
Add in the consistency with which they are able to reach that level and it is little wonder the Littler-Humphries rivalry is being talked about as one that could dominate darts for years to come.
“These two could have darts sewn up,” Sky Sports pundit Wayne Mardle said.
“They are going to be the mainstay of the darting world. Others are going to have to play really well to get the better of these two.
“If they have that hunger for four, five, six or even 10 years then someone is going to have to step up.”
Asked if he felt that he and Littler would be fighting it out at the top for the next 10 or 15 years, Humphries was less convinced.
“The problem is, there’s always another person who comes around the corner,” he said.
“In five years’ time there could be about 10 players who are as good as me and Luke and it could be a battle between us all.
“I’d love to say over the next 10 years we’ll battle it out in many finals – and we probably will – but they’ll probably be a lot of other names involved with us.”
For the time being, though, Humphries and Littler have put some distance between themselves and the chasing pack.
But even after 23 matches against each other in such a short space of time, there is no sign of familiarity breeding contempt just yet.
“I love him. I think he’s a good kid,” Humphries said of his teenage competitor.
“He’s a close friend of mine in darts. He’ll probably win much more than I’ll ever win in my career because he’s young and he’s a great talent.
“I’m just happy when I nab one here and there. I said to him on the stage, I’m really happy to win this but I’m sure he’ll get me back plenty of times in the future.
“It’s just another final in the Luke and Luke saga.”
The next stage in the saga will see the rivals become team-mates as they join forces for England at June’s World Cup of Darts in Frankfurt.
“I cannot wait,” Littler told Sky Sports. “He won it last year so hopefully he can lead me to victory.”
They should form a formidable duo but it is only a matter of time before they will be battling it out again on the oche in a major tournament.
And next time it is Littler, rather than Humphries, who might have a bit of revenge on his mind.
