South Africa shook off its early season rust with an 80-run win over Australia at St. George's Park Sunday to level the one-day series 1-1 and send it to a deciding game. Four South African batsmen made half-centuries in an imposing 303-6 and pacemen Morne Morkel and Lonwabo Tsotsobe shared six wickets to stifle Australia's reply as the top-ranked ODI team was bowled out for 223.
