Aussies steamroll Proteas to keep hot U19 World Cup form rolling

Australia's bowlers have fired again at the Under 19 World Cup, bowling out South Africa for 118 on route to a comprehensive six-wicket victory.

New ball pairing Charles Lachmund (3-29) and Will Byrom (2-16) blasted out the Proteas' top order after captain Oliver Peake won the toss and chose to bowl at the Namibia Cricket Ground.

A horror Powerplay saw the South Africans lose 4-37, with in-form batter and top-scorer Jason Rowles gone for six in the seventh over.

From there, SA couldn't recover, with only three players making double figures, the best of which was Paul James' 34 from 60 balls.

Even the Australian fielding had plenty of highlights, with Jayden Draper's direct-hit from side on ending Jorich van Schalkwyk's innings. 

James was the last to fall as Aryan Sharma (2-27) picked up his second wicket, with Australia bowling out their opponents in the 33rd over.

Although the Aussies lost Will Malajczuk (four) early in the chase, they were never threatened thanks largely to the composure of No.3 Steven Hogan (43).

It took a superb piece of catching from Armaan Manack to dismiss the dangerous Malajczuk in the third over, but the Australians ensured they wouldn't lose quick wickets like their opponents did in the previous innings.

Frontline quicks JJ Basson (3-41) and Bayanda Majola (1-23) toiled hard for South Africa but they didn't have enough runs to defend.

Hogan looked certain to guide his side home but chipped a simple catch to midwicket with only 25 runs left to get.

Alex Lee-Young (21no) and Draper (21no) got Australia over the line with six wickets in hand and a massive 103 balls to spare.

Australia now take on West Indies in Harare on Wednesday in their final match of the Super Sixes, with their spot in the semi-finals all but guaranteed.
