Campbell Hatton survived the first serious test of his young career with a generous points win that soured the Spurs crowd.
The 20-year-old son of British ring legend Ricky had just his fourth pro fight on the undercard of Anthony Joshua vs Oleksandr Usyk.
And the big occasion got to him as he went life and death with Spanish journeyman Sonni Martinez and escaped with his unbeaten record by the skin of his teeth.
Referee Marcus McDonnell scored the fight 58-57 and the thousands of people filing the Tottenham stadium booed his decision.
Martinez had to take some of the blame however, as he Hatton looked shattered for the final two rounds and he chose to mug and showboat instead of looking for the knockout.
All the atmosphere had already been sucked out of the stunning new Tottenham stadium by the sickening ending to the previous bout.
