South Africa U-19s 77 (Mahmood 3-12, Rhodes 2-9, Wood 2-14) trail England U-19s 393 (Jones 52, Makhanya 4-48) by 316 runs
South Africa Under-19s were fired out for just 77 and closed the second day at Wantage Road staring defeat in the face after conceding a first-innings lead of 316.
England will surely enforce the follow-on on day three and will have two days to wrap up victory and win the two-match series.
It was an afternoon of carnage for the tourists who registered only three double-figure scores, two of them from Nos. 8 and 10. Extras, with 15, was the top scorer.
The South Africans played out the first 10 overs of their innings unscathed but Nottinghamshire's Luke Wood, a left-arm seamer, began the rout with two wickets in successive balls, bowling Mathew Christensen and having Hanco Olivier lbw.
Opener Ryan Rickelton was third man out for 12 before three wickets fell for two runs, all to Lancashire right-armer Saqib Mahmood, who finished with 3 for 12.
Three successive ducks left South Africa 30 for 6 and Stefan Klopper's 12 and Brandon Glover's 10 merely turned the effort from utter humiliation to extreme embarrassment. Sort of.
England took a giant lead after they had earlier extended their 252 for 3 to 393 through several handy partnerships, all marshalled by Rob Jones' half-century.
