South Africa defeated Namibia 4-1 in the 2018 COSAFA Cup plate semi-final match at the Old Peter Mokaba Stadium on Tuesday.
As a result, Bafana Bafana will take on the winner between Botswana and Swaziland in the plate final on Friday, while the Brave Warriors are out of the competition.
The Namibians started brightly and they nearly took an early lead but Bafana Bafana took charge of the game in the 25th minute after breaking the deadlock from a goal from the penalty spot by Aubrey Modiba.
Maboe doubled the lead just three minutes later before Deon Hotto pulled a goal back six minutes before the break.
Maboe scored his second just a minute late while Siyanda Xulu completed the rout in the second half.
