Olly Stone will today hope to lead England Under-19s to victory in the opening Youth Test against South Africa in Cape Town.

The 19-year-old Northamptonshire player from Brundall, who is captaining the England side, had a quiet day personally yesterday – but his team-mates worked their way into a commanding position.

South Africa will resume this morning (8am GMT) still needing 205 more runs to win on the final day, with six second innings wickets intact.

England started the third day yesterday on 24 without loss and they advanced to 93 for two before a dramatic collapse in the afternoon session.

They lost five wickets in 15 overs for the addition of just 22 runs, with Surrey's Dominic Sibley (62) top scoring.

Stone, who plays club cricket for Vauxhall Mallards, dropped down to number 11 having suffered a dislocated finger before the second day and he was the last man out, for one, as England posted 151 – a lead of 270.

Stone, who claimed four wickets in the first innings, opened the bowling for England, although his four-over spell was wicket-less.

He was replaced in the attack by Sussex's Harry Finch and he bagged three wickets in six overs to put England firmly on top.

Miles Hammond claimed England's fourth wicket and South Africa closed on 66 for four, with opener Andries Gous unbeaten on 30.
