Australia and South Africa continued their unbeaten run to set up a semifinal clash in the Under-19 World Cup after posting contrasting wins in their Super League quarter-finals on Sunday.

Defending champion Australia earned a hard-fought five-wicket at the Endeavour Park in Townsville over Bangladesh. Australia captain Will Bosisto led from the front as his side overcame the loss of early wickets to chase down Bangladesh’s total of 171.

South Africa, on the other hand, was clinical in its performance against England in the other Super League quarter-final as it registered a 103-run victory. South Africa’s Prenelan Subrayen was the star of the win with the ball at the Tony Ireland Stadium in front of ESPN STAR Sports’ HD cameras.

Australia and South Africa will now clash in the first semi-final on Tuesday.

India, Pak to clash

Meanwhile, on Monday, arch rivals India and Pakistan will meet at the Tony Ireland Stadium in the third quarter-final. Both India (2000 and 2008) and Pakistan (2004 and 2006) have won the title twice.

This will also be the first of two potential meetings between the two Asian powerhouses this year in ICC events. If all goes according to ICC World Twenty20 Sri Lanka 2012 seedings, then the two former champions could clash in the Super Eight stage at R.Premadasa Stadium in Colombo on 30 September.

New Zealand and West Indies will figure in the fourth and final quarter-final, also on Monday, at Endeavour Park 1. Both sides have appeared in an ICC U19 Cricket World Cup final but are yet to win the title. New Zealand lost the final to England in 1998 while the West Indies lost to Pakistan in the 2004 final.

The winners of India-Pakistan and New Zealand-West Indies matches will play in the second semi-final on Thursday.

Clinical South Africa too strong for England

South Africa, set up a semi-final clash with Australia on Tuesday with its 103-run victory over England, which was bowled out for 141 in pursuit of the young Proteas’ total of 245.

Opener Quinton de Kock, South Africa’s leading run-getter, was an early casualty (dismissed for seven by Jamie Overton) but captain Chad Bowes (46: 54b, 6x4), left-hander Murray Coetzee (67: 83b, 6x4) and all-rounder Theunis de Bruyn (54: 65b, 6x4) combined to get Proteas to a useful score.

England seamer Reece Topley (three for 45 from 10 overs) bowled well at the death and after the game, South Africa captain Chad Bowes felt his side had fallen probably 40 runs short of where it wanted to be.

Top order duo of Ben Foakes (54: 72b, 4x4,1x6) and Alex Davies (54: 103b, 6x4) were the only key contributors for  England as it was bundled out for 141 in the 41st over.

Subrayen, the man of the match, removed Foakes to break a century partnership with Davies, and went on to snap up four for 24 from 10 overs, including Davies.

Australia secures win over Bangladesh

Australia pulled off a five-wicket victory over Bangladesh to seal its spot in the ICC U19 Cricket World Cup 2012 semi-final.

Australia captain Will Bosisto won the toss and elected to bowl in overcast conditions at Endeavour Park in Townsville.

Left-handed Bangladesh opener Soumya Sarkar got Bangladesh off to a good start combining well with Liton Das for an opening stand of 64.

The opening partnership was broken by a superb fielding effort from West Australia’s Cameron Bancroft to run out Das for 22 (45b,2x4).

Ashton Turner was the first to strike with the ball picking up the wicket of Bangladesh captain Anamul Haque caught behind by Queensland’s James Peirson.

In its reply, Australia got off to a wobbly start losing the wickets of Bancroft (1), Victoria’s Meyrick Buchanan (0) and New South Wales’ Kurtis Patterson (0) in the first five overs.

Player of the match Bosisto (71 not out: 134b, 7x4) was again outstanding for the young Australia side, playing patiently and maturely, combining with fellow Western Australian Turner for a sixth wicket unbeaten stand of 72  to take his side to victory in the 45th over.
