JUNIOR welterweight Derek `Teacher’ McKenzie had a rare victory on February 14, 1983. McKenzie won a points decision over Englishman Delroy Pearce at the Concert Hall in London, England. The victory was the third in 11 fights for the Guyanese who had taken up residence in Fulham, England. 

He drew against Winfield Braithwaite on his professional debut in 1979. His second time in the ring ended in a defeat at the hands of Trinidadian Michael Parsons in the Twin-island Republic. McKenzie claimed his first professional scalp in the third fight.
On May 20, 1980 the `Teacher’ schooled Clifford `Piggy’ Griffith to win the 10-rounder on points. He then lost the next five successive fights, one being to Lloyd Honeyghan. The Teacher returned to Guyana in June 1986 for his last contest.
An unbeaten Marcelle Daniels made sure McKenzie’s career ended on a losing note after winning by TKO in the eighth round.
