Eibar held Alaves to a scoreless draw in Thursday’s all-Basque clash at Estadio Mendizorroza despite having goalkeeper Asier Riesgo sent off.
Riesgo saw red in the 26th minute after handling the ball outside his area following a mix-up at the back with Flioran Lejuene.
Midfielder Adrian was the man withdrawn for replacement keeper Yoel and the 10 men dug in to grind out a point.
Eibar remain 8th and are now eight points behind Athletic Bilbao who occupy the final European spot, with only four games remaining while Alaves stay 10th.
