Swansea City Under-21s Keston Davies Daniel James new contracts
Centre-back Davies has signed a two-year extension while pacey winger James has signed a three-year deal.
The pair have impressed in the club's development squad, and are now hoping to continue their progress at the Swans.
Davies, 19, who hails from Killay, began his career with Swans academy at the age of nine.
"I am over the moon," he said. "It is great to secure another two years here to continue my football development.
"It means everything to me and my family to sign this new deal. It will allow me to focus on my game and push on to achieve my next goal.
"The hard work starts now. I've felt I have had a good season with the Under-21s so far - I have had to be patient and wait for my chance but I have played a number of minutes and managed to score a few goals.
"I want to push on and help the team go as far as we can over the next few months."
James, who joined from Hull City's academy in August 2014, has also extended his stay in SA1.
The 17-year-old Welsh international has been a regular for the Under-21s this season and was also included on the bench for the first-team's FA Cup tie against Oxford last month.
"Just being around the first team for that weekend was an amazing experience," he said.
"Training with players like Andre Ayew and Gylfi Sigurdsson has been amazing. It is physically and mentally much harder but it has helped me develop.
"Ever since I made my switch from Hull I knew it was the right thing to do. Being at the club has really helped me improve my game.
"Moving away from home at age 16 was difficult at first, but I feel I have matured a lot because of the move.
"I am thrilled to have extended my contract here but I can't relax and just settle, I have to keep working hard and look to impress on the pitch.
"My aim is to make a first team appearance as soon as I can. If I get given a chance I must take it."
