Twelve months on from breaking their Wembley duck, Lee Radford's men became the first Hull FC team to retain the famous trophy after a dramatic 18-14 win over Wigan Warriors in an absorbing Ladbrokes Challenge Cup final.
Architect of their hard-fought victory was scrum-half Marc Sneyd, who became the first player to lift the Lance Todd Trophy outright for the second successive year courtesy of another masterclass kicking display.
With both sides scoring three tries apiece, the result came down to the marksmanship of Sneyd, who landed all three conversions but, more importantly tormented Wigan with his pinpoint tactical kicking to deny them a record-extending 20th victory.
After John Bateman opened the scoring in the fourth minute, Hull responded through Fetuli Talanoa and Mahe Fonua.
Oliver Gildart went over in the 32nd minute to reduce the deficit to 12-10 at half-time, before Fonua's second try proved crucial for Hull.
Joe Burgess crossed to set up a nervy final eight minutes but Hull held on.
