Islington BC’s Tyrone Negasi produced his best performance to date as he reached the semi-finals of the NABC Championships with a second-round stoppage.

Negasi overcame Eastgate’s Matthew Rose in his quarter-final clash at Camberley on Saturday – and he was joined in the last four by clubmate Ben Turner, who stopped Ryan Ayton (Centurions).

From the opening bell, Negasi piled the pressure on his opponent as he launched head to body attacks at a frantic pace and Rose took a standing eight-count before the bell signalled the end of the round.

The Islington fighter kept the pressure on in the second, forcing another count and following that up with another two-fisted barrage that led the referee to stop the contest.

However, Turner took some time to adjust to his opponent’s awkward southpaw style and the contest was something of a cagey affair before he stepped up the pace in the second round.

A series of long, straight punches put Ayton under pressure, forcing a count, and there was no let-up from Turner, who unleashed a non-stop array of punches that prompted the referee to intervene halfway through the final round.

Islington duo Nehemiah Thomas and Sherif Musah returned victorious from the Ruislip ABC show after taking unanimous points decisions against home fighters.

Thomas executed his jab and move tactics to perfection, using straight punches early on and mixing in hooks as the contest progressed to run out a clear winner against Ruislip’s J Mitchell.

Musah started slowly against Reece Webb (Ruislip), but gradually ran through his full repertoire of hooks and uppercuts to the head and body to secure a well-earned decision.
