Goals from Will Smallbone and Jonathan Afolabi earned a 2-1 win against Newcastle United that put Southampton level on points with Premier League 2 Division 2 leaders Wolverhampton Wanderers.
First-team manager Ralph Hasenhuttl watched the Development squad's second victory in four days, after a 3-0 Premier League International Cup triumph over West Ham United on Tuesday.
Smallbone broke the deadlock on 54 minutes, when he found the net from close range after a scramble in the penalty area.
Afolabi made it 2-0 following good work by Nathan Tella eight minutes later, before Callum Roberts scored a 75th-minute penalty for the visitors at Staplewood.
But Saints held on to move up to third on 24 points, behind Wolves and second-placed Reading on goal difference.
Newcastle are five points behind Southampton in sixth position.
