The Englishman's team, Dom can't cook, scored 103 points thanks to a left-field captaincy choice.
Twenty-eight of those points came as a result of giving Bernardo Silva (£7.5m) the armband.
Silva was captained by only 4,646 Fantasy managers, making him a major differential for those who took the plunge.
Jack also doubled up on Liverpool defenders for their home match with Southampton.
The Reds won 3-0 and his picks delivered more than just clean-sheet points.
There were also solid returns up front.
A first goal in three Gameweeks for Harry Kane (£12.4m) brought in nine points.
As the manager with the highest score among those not using any of their chips, Jack wins a copy of FIFA 19, a Nike Merlin match ball and an FPL rucksack and mug.
