" I believe that the person who will take Ruann's career to greater heights is Strydom."
Moyo, whose corner was manned by Soon Botes, improved to nine wins, five losses and two draws.
Visser said: "I thought I won the fight. Yes, I waited too long and did not work hard but still I scored with my jabs."
Earlier in the afternoon, Justice Siliga revived his chances of challenging Visser for the SA heavyweight title by defeating Luke Sutherlands in their closely contested eight rounder, which was the title eliminator.
"I am excited that finally I got to fight. The next time fans see me in the ring will be against Ruann."
