Athletic Club moved to 13th on the table with a 1-0 home win over Granada on Monday.
Veteran striker Aritz Aduriz headed the game’s only goal, his 12th of the season, at the far post in the 67th minute from a corner by Ibai Gomez.
But Athletic had to play the last 10 minutes with 10 men after midfielder Markel Susaeta was sent off for a second bookable offence for a clumsy tackle on Manuel Agudo.
Granada came close to equalizing in injury time but Yacine Brahimi’s right-foot shot hit the post.
In the battle for seventh place, Real Betis and Getafe played out a goalless draw.
