After finishing fifth in the standings, Castilla now knows its path in the promotion playoff to Segunda. Our reserve team will face Sabadell, the second-placed team from Group II, in the first round. The two-legged tie will begin on the weekend of May 30-31 at Alfredo Di Stéfano Stadium and will be decided a week later away from home.

If Castilla progresses past this round, they will face a second playoff round against the winner of Villarreal B-Zamora to decide promotion to Segunda.
