England Under-19s 313 (Barnard 114, Williams 4-71) and 151 (Sibley 62, Pillay 3-23) beat South Africa Under-19s 194 (Stone 4-40) and 163 (Gous 83, Finch 3-11) by 107 runs
It took just over a session of the final day for England to wrap up the opening Test with Gavin Griffiths taking two important wickets.
Andries Gous had held England up with a fine 83 from 162 balls but when he was bowled by Griffiths, any faint chance that South Africa retained of chasing 271 was extinguished. Griffiths then sealed victory by having Clyde Fortuin caught by Ed Barnard - who was named man of the match for his first-innings century.
South Africa needed another 205 runs for victory on the day four and badly needed a partnership to have any chance. But the day began in poor fashion as two wickets went down for just 17 runs.
Finally, Gous found a partner in Fortuin and the pair batted to lunch at 141 for 6. But again they failed to deal with the start of a new session and in the second over of the afternoon Gous was gone and South Africa were staring defeat in the face. The final two wickets added only 11.
South Africa will hope to square the series in the second Test at Paarl which begins on February 3. They have called up Tshepo Moreki, a 19-year-old right-arm bowler who has taken seven wickets in three first-class matches for KwaZulu-Natal this season, to replace Craig Kirsten who only bowled four overs in this Test before breaking down with a stress fracture of the lower back.
