Goalkeeper Christian Dibble has signed a new contract at Oakwell, which runs until the summer of 2016.
The 20-year-old's progress in the Reserves and out on loan, more recently with Nuneaton Town, has been rewarded by Reds boss Danny Wilson.
Speaking to barnsleyfc.co.uk, Dibble said,"I'm delighted to sign a new deal. I'm really enjoying my time here and I feel I have developed so much in the past year.
"Working with Mark Crossley (Goalkeeping Coach), Ross Turnbull and Adam Davies has really helped me in my development and I want to keep it going."
Last year Dibble was called into the Wales Under 21s squad and has appeared several times on the first-team bench for the Reds.
