The double-start showpiece will be the sixth televised final between the pair. Littler prevailed in August’s World Series in Australia, while Humphries got the better of him in May’s Premier League - a neat framing for tomorrow’s rematch.
It's a chance for Littler to claim one of the few PDC majors still missing from his collection, having fallen at the first hurdle on his World Grand Prix debut last year.
For Humphries, it represents a third consecutive final in the tournament, a shot at reclaiming the title he won in 2023 and atoning for last year’s semi-final reverse to Mike De Decker.
Littler reached the final with ruthless scoring, less than 24 hours after an epic quarter-final with Welsh star Gerwyn Price. He controlled the semi against 2021 champion Jonny Clayton, winning 5-1.
The teenager set the tone with a 161 checkout in the opening set and moved quickly to 2-0, only for Clayton to respond with finishes of 154 and 128 to drag the match back.
That only seemed to sharpen Littler as he produced a stunning 140 checkout in the deciding leg of a tense fourth set to blunt Clayton’s comeback before running off six legs in a row to close the match.
“I’m really happy with the performance -- the stats showed it,” Littler said afterwards. “That 140 was the big moment. Going 3-1 up settled me, and I think it killed Jonny off a bit. I’m just glad to be in the final.”
Humphries earned his place with another display of heavy scoring, dismantling Danny Noppert. The world No. 1 opened with a 110 average, taking the first set with checkouts of 155 and 108, and then averaged close to 116 in the third as he surged into a 3-0 lead.
Noppert fought back to make it 4-3, but Humphries found finishes of 135 and 110 in the decisive set to wrap up a 5-3 victory.
“It was a great game,” said Humphries, who now joins Phil Taylor and Michael van Gerwen in reaching three successive World Grand Prix finals.
“Danny pushed me all the way, and I got a bit frustrated, but I came out fired up in the eighth set, and it seemed to work. Some people question my mentality, but I showed resilience tonight. The break at 4-3 probably did me a world of good.”
Revenge will be on Littler’s mind after his defeat to Humphries in the Premier League, and there is the extra incentive of chipping away at the lead for the world No. 1 spot.
“I definitely owe Luke one,” the Warrington native said. “He’s got a great record here, but it’s all new for me. Last year I lost in the first round -- now I’m in the final. Hopefully I can get the win and put some pressure on him for that top spot.”
