Woodhouse and Hamilton went hell for leather in a stirring 12-round scrap in Hull, a throwback to classic closely-contested and straight-up domestic fights.
The scores came in 116-115 and 116-114 for Woodhouse and 116-113 for Hamilton. The split decision win in a see-saw thriller elevates new champion Woodhouse’s record to 22-6 (13 knockouts) while ex-champ Hamilton is now 14-3 with three knockouts.
Realising the dream of becoming a domestic champion after spending much of his younger years representing various Football League sides may be the end of the road for Woodhouse, however.
After the bout he admitted that pre-fight promises to retire, win or lose, were not hollow, and that he still plans to vacate the title and call it a day.
”The last thing I told my late father, Bernard, was I would become champ," an emotional Woodhouse explained.
"I want to bow out as a champion. I have fought some really good guys but that was the hardest fight of my life."
He also all-but confirmed rumours that he had placed a £5,000 bet on himself to one day become British champion at odds of 50/1.
“I cannot confirm or deny I had a five-grand bet on myself to win at 50-1 – but the drinks are on me tonight!"
The Matchroom event was headlined by Tommy Coyle, who overcame four knockdowns to retain his IBF international lightweight title against Daniel Brizuela in Hull.
On the undercard, Gavin McDonnell – twin brother of former IBF bantamweight champion Jamie – claimed the British super-bantamweight title with a rousing sixth-round stoppage of previously-unbeaten Leigh Wood.
And London 2012 Olympian Luke Campbell stopped Scott Moises in the final round of their eight-round battle.
