South Africa have won the second One-day International against Australia by three wickets at Perth on Sunday.Proteas skipper AB de Villiers had vowed his side would be seeking redemption after being beaten by 32 runs in the series opener on Friday. His team backed those words with a superb bowling display as the home side were dismissed for just 154 in 41.4 overs on what appeared a good batting wicket. Towering pace man Morne Morkel led the way for South Africa with 5 wickets for 21 runs, his second five-wicket haul in one-day internationals and career-best figures in a man-of-the-match performance.
