Former African champions Orlando Pirates were humiliated 4-1 by third-tier Maluti College Saturday in the biggest shock of the 43-year South African FA Cup.
And the result of the first round match in central town Phuthaditjhaba could have been even more embarrassing for the 1995 CAF Champions Cup winners as the amateurs had a timidly-struck penalty saved.
Pirates lie second in the national league, two points adrift of fierce rivals Kaizer Chiefs with a match in hand, and were expected to cruise into the last-16 round of the Cup.
But a side containing several of the South African 2013 Cup of Nations squad plus Namibia, Nigeria, Zambia and Zimbabwe national team players were in trouble from the opening minute.
Maluti captain Lucky Mokoena won a race for possession with goalkeeper Senzo Meyiwa and his shot trickled over the line at austere Charles Mopeli Stadium, the home of Premiership outfit Free State Stars.
A diving Mashale Rantabane header midway through the opening half doubled the advantage of the students and Mokoena put his team three goals ahead before the missed spot-kick.
Pirates reduced the arrears on the hour mark through Oupa Manyisa, but the anticipated comeback never materialised and Rantabane put the outcome beyond doubt with a close-range header nine minutes from time.
The Soweto Buccaneers have lifted the South African FA Cup seven times -- a feat bettered only by the 12-title Chiefs -- and were among the favourites for the $680,000 (520,000 euros) first prize.
Chiefs brushed aside fellow Premiership club Bidvest Wits 3-0 in north-east city Nelspruit through goals from defenders Siboniso Gaxa and Morgan Gould and substitute midfielder Mandla Masango.
Far more was expected from the most attractive tie of the last-32 round, but a Wits team guided by 1996 Africa Cup of Nations-winning coach Clive Barker rarely threatened to cause an upset at a packed Mbombela Stadium.
Mbombela became infamous during the recently completed 2013 Cup of Nations as a grass infection turned the pitch into a hard, sandy embarrassment that resembled creamed spinach to a worldwide TV audience.
Title-holders SuperSport United won on penalties after a goalless stalemate with Moroka Swallows near Pretoria and bottom Premiership club Chippa United lost 3-2 after extra time to second-tier United FC in Rustenburg.
