Zelfa Barrett claimed the vacant WBA Intercontinental lightweight title with a fifth-round stoppage of Gavin Gwynne at Wembley Arena.
Former British, Commonwealth and European lightweight champion Gwynne was five inches taller than his opponent but was floored by an uppercut from the quicker fighter.
Manchester's Barrett, 33, extended his record to 36 wins and three defeats with 19 knockouts, and has won five fights in a row.
Gwynne went into the fight on the back of an impressive majority decision win over previously unbeaten Khaleel Majid in May.
However, the 36-year-old, from Merthyr in south Wales, now has a record of 19-5-2.
Barrett will hope victory on the MF Pro card gives him a chance to move up the WBA rankings at 135lbs.
