Reigning champion Littler is yet to taste defeat in Wolverhampton and he will be aiming to preserve his unbeaten run when he takes on three-time Women’s World Matchplay champion Greaves.
Greaves recorded a memorable victory when the pair met in last year’s Winmau World Youth Championship semi-finals and will take on the world number one for a first time on the big stage.
A high-profile Group A is completed by Dutch Darts Champion Niels Zonneveld, who will await both Littler and Greaves on Sunday and Monday in further round-robin ties.
The newly-expanded 48-player tournament will take place at WV Active Aldersley from November 14-22, as the sport’s biggest names go head-to-head for the iconic Eric Bristow Trophy.
In a change to previous years, the players are split into 16 groups of three, with only the group winner advancing to the knockout stages.
The opening round-robin games will take place during a bumper double session on Saturday, with 2023 champion Luke Humphries pitted against former Masters champion Joe Cullen and PDC Asian Champion Paolo Nebrida in Group I.
Dutch number one Gian van Veen will headline Group M, as the world number three prepares to take on former World Youth Champion Bradley Brooks and debutant Carl Sneyd.
Three-time champion Gerwyn Price kicks off his campaign against Challenge Tour champion Joe Hunt, with Poland’s number two Sebastian Bialecki also awaiting in Group E.

Format
16x groups of three players
Top 16 qualified players from PDC Rankings seeded. Next 16 qualified players from PDC Rankings numbered 17-32 for draw, and remaining players numbered 33-48 for draw (with any players without a ranking listed at the end in alphabetical order).
Seeds will be allocated to groups in the following order for the Group Stage:
Group A - Seed 1
Group B - Seed 16
Group C - Seed 8
Group D - Seed 9
Group E - Seed 4
Group F - Seed 13
Group G - Seed 5
Group H - Seed 12
Group I - Seed 2
Group J - Seed 15
Group K - Seed 7
Group L - Seed 10
Group M - Seed 3
Group N - Seed 14
Group O - Seed 6
Group P - Seed 11
In the Group Stage, two points will be awarded for a win, and no points are awarded for a defeat.
Should there be a three-way points tie in any group after the round-robin games have been played, these would be split as follows:
Total Leg Difference
Total Legs Won
Total Legs Won Against Throw
Highest Total Tournament Average (to two decimal places)
Highest Winning Match Average (to two decimal places)
If players cannot be split after the above criteria has been applied, a play-off will be organised between the players at the end of the session in which the final group game is played, and will be a two-way or three-way nine-dart shoot-out in which the player scoring the most points is deemed the winner, the player scoring the second highest points total would be deemed to have finished second in the group, with the lowest total finishing third. The order of throw would be determined by PDC Ranking, with the highest-ranked player having the option to throw first, second or third (if applicable), and the second-highest ranked player then having the second option of which order to throw in should there be three players involved. Should any scores be tied after nine darts, those players would continue throwing three darts apiece until there is a separation.
Following the completion of the Group Stage, each group winner will progress to the knockout stage from the Last 16 onwards, and the tournament will proceed in bracket order as follows:
Winner Group A v Winner Group B
Winner Group C v Winner Group D
Winner Group E v Winner Group F
Winner Group G v Winner Group H
Winner Group I v Winner Group J
Winner Group K v Winner Group L
Winner Group M v Winner Group N
Winner Group O v Winner Group P
