Bilbao and Granada claim wins
Athletic Bilbao tightened their grip on fourth spot in the Primera Division with a narrow 1-0 victory over Getafe on Saturday.
Markel Susaeta hit the only goal of the game in the 39th minute and although Athletic were easily the better side, they were unable to extend their lead.
The win sees Ernesto Valverde's men move a step closer to Champions League qualification, while Getafe remain dangerously close to the relegation zone.
Granada moved a step closer to securing their top-flight status for another season with a 1-0 win over 10-man Elche at Los Carmenes.
Yacine Brahimi's strike midway through the second half settled the contest in favour of Granada, who made it three home victories on the bounce following their successes over Villarreal and Real Betis.
It could have been a more comfortable victory for Granada in the end but Fran Rico missed from the spot in the 73rd minute after visiting defender Cristian Sapunaru had been sent off for bringing down Youssef El Arabi.
Real Valladolid and Rayo Vallecano, meanwhile, shared a 1-1 draw which did little to help either side in their fights to avoid relegation.
The hosts took an early lead through a Ze Castro own goal, but Alberto Bueno levelled things up with a goal against his former club before half-time.
The result means Valladolid will end the weekend still in the drop zone, three points worse off than their opponents and with just one win in their last eight matches.
In the day's other game, Espanyol and Levante shared a goalless draw.
