Littler, also a Premier League and World Series of Darts Finals champion in 2024, added another televised crown to his growing haul to cap off a record-breaking campaign at WV Active Aldersley.
The 17-year-old had raced through the group stage with three wins for the loss of just four legs, before surviving a match dart to edge out World Grand Prix champion Mike De Decker in a gripping last 16 tie.
Littler then powered through to the semi-finals with a 16-2 demolition of Jermaine Wattimena, which set up a fascinating showdown against two-time World Champion Gary Anderson in the semi-finals.
The Warrington wonderkid won through a 31-leg epic against Anderson in a pulsating last four clash, recovering from 13-9 adrift to triumph with a 103 average and 16 maximums. Anderson produced an inspired seven-leg blitz to seize control against the teenage sensation, conjuring up 164, 142 and 102 checkouts during this spell to race into an 11-7 lead.
Littler fought back from the brink to level at 14-14, before landing three 180s in the last two legs to deny the two-time World Champion in a breathtaking deciding-leg shoot-out. The teenage superstar then produced one of the most dominant displays in Grand Slam history to demolish Lukeman and become the ninth different player to lift the iconic Eric Bristow Trophy.
Lukeman won the opening two legs in 27 darts to seize the early initiative, but then it was one-way traffic, as Littler won 16 of the next 17 legs to pocket the £150,000 top prize, along with the £3,500 bonus he claimed from topping his group.
