Walker (right in the picture) has been at the club since he was eight years old and along with Curtis Wynter, Jermaine Grandison and Ashley Cain will be part of the first team squad after graduating from the Academy.
"I'm delighted to have gotten my first contract so the next thing now is pre-season and then looking forward to the season, said Walker to Sky Blue World.
"I suffered an injury earlier this year which put paid to the last couple of weeks of last season for me but now I'm running again and I want to be ready for when the season starts."
