Deyverson's 44th-minute goal gave Alaves a 1-0 win in the Basque football derby at home against Real Sociedad, while Real Betis beat Osasuna 2-0 in La Liga.
Alaves would have won by more goals on Saturday but for a stunning performance from Real Sociedad keeper Geronimo Rulli who produced a series of saves to keep the home side at bay, reports Xinhua news agency.
The win took Alaves' points tally to 40 from 28 games as they remained in the 10th position, while Sociedad remained sixth.
Finally, Betis moved a step closer to assuring their top flight survival by giving another blow to Osasuna with first half goals from Rafa Navarro and Ruben Castro in a straightforward 2-0 win in Seville.
Following the win, Betis moved to the 13th spot with 31 points from 28 games, while Osasuna remained in the 20th spot with 11 points from 28 matches.
Earlier in the day, league leaders Real Madrid registered a narrow 2-1 win away against Athletic Club Bilbao.
Madrid can thank a solid defensive display and goals from Karim Benzema and Casemiro for the victory against a rival, who could count themselves slightly unlucky not to have taken a point since they saw more of the ball.
The key to the game was the home side's failure to consolidate following Aritz Aduriz's 65th minute equaliser and allowing Casemiro a simple finish following a corner three minutes later for the deciding goal.
The day kicked off with Eibar and Espanyol drawing a forgettable encounter 1-1. Eibar opened the scoring through Kiko Garcia after 20 minutes, but Jose Jurado equalized an error strewn game five minutes after halftime.
