Real Madrid Castilla drew 1-1 at Segunda B opponents Gernika.
The result keeps Zinedine Zidane's charges within touching distance of the leadership.
Castilla found themselves up against an organised and defensively well-drilled Gernika outfit.
Zidane's men probed right to the final whistle and created the chances to take all three points at Urbieta, but lacked the rub of the green in front of goal. Mariano Díaz, who now has 11 to his name this season, got the visitors' only strike.
