Mitch Duggan, Evan Gumbs and Luke Pilling have all been offered one-year extensions to their contracts at Tranmere Rovers.
The trio – all current first-year professionals – have spent much of the season out on loan as part of their development.
Duggan has played more than forty-five games for Marine AFC and Trafford and has shown his versatility by playing right-back, centre-back and centre midfield.
Goalkeeper Pilling spent time on loan at Trafford and Glossop North End and also made his Wales under-19 debut during the 2015/16 campaign.
Gumbs spent the first half of the season at Burscough and Trafford before helping Salford City to promotion to the National League North in the second half of the campaign, making more than forty appearances at right-back and centre-back.
Manager Gary Brabin said: “All three have progressed really well this season and deserve this opportunity.
“They’ve developed in their time out on loan and have really benefitted from regular competitive football.
“We’ve had good feedback from the clubs they’ve been at whom we thank for the part they’ve played in their development.”
Sam Ramsbottom, Liam Davies and Ben Jago have all been released, with their contracts at Prenton Park ending this summer.
