Saints youngsters Cody Cropper and Jake Sinclair have signed new one-year contracts with the club.
The development squad duo follow in the footsteps of Omar Rowe and Sam McQueen in extending their deals.
American goalkeeper Cropper, 21, told Saints’ website: “It feels great to sign.
“I think it’s a great opportunity for me, as a player, to come in and work hard under the new staff and hopefully earn another contract.”
Sinclair, a 20-year-old forward, said: “I’m delighted to sign.
“I’ve been here since I was eight and hopefully I can carry on progressing as I was last season and hopefully I can get in the manager’s plans for this season.”
