The Junior Springboks set up a World Championship rugby final against old foes New Zealand on Friday after crushing Argentina in last night's one-sided semifinal at Newlands.

• South Africa (22) 35
• Argentina (0) 3

Wing Raymond Rhule, who entered the match early in the first half as a replacement for the injured Paul Jordaan, scored two tries to stake a claim for a start in the final.

Flyhalf Handre Pollard scored 12 points from three conversions and two penalties, while centre Jan Serfontein and hooker Mark Pretorius also scored tries.

This final will mark the first time the junior Boks have got to an age group final since 2007, when they went down in the under-21 world championship to France in Clermont.

Since the International Rugby Board introduced age-group world championships in 2002, South Africa's record has only been bettered by New Zealand.

The Baby Boks won the 2002 and 2005 under-21 titles and also collected the 2005 under-19 world crown. But, since the under-19 and under-21s were scrapped, to make way for the under-20 event, New Zealand have ruled.

Yesterday Argentina were swept aside with ease even though they had advanced to this semifinal after beating France, Australia and Scotland in a tough group.

The emphatic nature of South Africa's win, just four days after a brilliant, four-try, second half against England in their final pool match, suggests they have timed their run well. But they might have lost captain, and centre, William Small-Smith with a knee injury, which will be a blow against a Kiwi side boasting a strong backline.

New Zealand were too strong for Wales in the first semifinal, winning 30-6
