The SA Schools slipped up for the second match in succession of the International U19 series being played in the Western Cape.
Paarl Boys High, unbeaten in 53 matches in South Africa in the last three seasons, did not have one starting player in the run on XV and only flanker Vian Fourie was deemed good enough to make the match-day squad.
Western Province, whose Schools Premier Division is considered the toughest in the country, had only one representative in the run on XV.
The SA Schools, beaten 30-28 by Wales in Saturday’s opener, lost 13-8 to France to end any prospect of winning the quadrangular featuring South Africa, France, Wales and England.
SA Schools team Tuesday’s matches were hosted at Paarl Gymnasium in Paarl. The opening matches were played at Paul Roos Gymnasium in Stellenbosch and the tournament will be completed at City Park on Saturday.
England beat France 24-8 in their opening match and lost to Wales 14-12 on Tuesday.
Wales are now favourites to be crowned champions.
