Iqraam Rayners netted twice while Richards Bay captain Simphiwe Mcineka netted an own goal, but it was Mabena's goal that got Cardoso racing down the touchline to celebrate with the youngster and his teammates.
Mabena missed a large part of last season through injury and only made two appearances in the Betway Premiership, but he will now be looking to get some more minutes this time around.
The 18-year-old was introduced in the 72nd minute by Cardoso, who revealed it was important to use all five changes on the day.
“Obviously, it was important to start strong. We made two weeks preparations so we knew that taking the game for the last stages, last minutes or even for extra-time will never be good for us,” Cardoso told SuperSport after the game.
“But I think the team understand the message, we started very strong, scored and it was important to manage some of the situations we had.
“Some substitutions that we needed to make, managing so that we can keep the pace, congratulations to the players."
