Windhoek, Jan 14 (UNI) Australia, South Africa, Afghanistan and Sri Lanka were the four teams in action on the final day of warm-ups in Namibia, as rain-affected matches brought the practice phase to a close on the eve of the ICC Under-19 Men’s Cricket World Cup. Australia v South Africa: South Africa won the toss and elected to bat, but their innings got off to a nightmare start. Australia struck early and often, with Charles Lachmund cleaning up Jorich van Schalkwyk for a duck before Ben Gordon’s sharp pace accounted for Adnaan Lagadien (0) and captain Muhammed Bulbulia (7).
