Tenerife produced a dominant display to boost their Primera Division survival hopes with a 2-1 victory over Racing Santander who remain right in the thick of the battle.
The hosts were rampant from first whistle to last and only a string of magnificent saves from Racing keeper Fabio Coltorti prevented them from running away with the game.
But as luck would have it, Coltorti proved to be the villain as his foul on Alejandro Alfaro allowed Ayoze Garcia to slot home the penalty which ultimately settled the match.
It was harsh on Coltorti, who had performed heroics either side of Roman Martinez's opener to allow substitute Xisco to give the visitors hope with a second-half strike.
But the defeat means they slip to 16th in the table, one point and two places above victorious Tenerife.
Coltorti saved from Roman Martinez after Ricardo Leon's early free-kick before Sergio Canales warmed Sergio Aragoneses' palms at the other end.
Canales shot wide but Tenerife were soon threatening an opener, with Nino's 12-yard effort forcing a superb reaction save from Coltorti before Juanlu Hens sent a 25-yard free-kick against the post following Oriol Lozano's foul on Nino.
Canales was the only Racing player to make an impact in the first half and, after Ricardo fouled Manuel Arana, his free-kick flew over the bar.
Tenerife dominated the rest of the first half, but Ayoze was off target from 20 yards before Marc Bertran's cross was headed over by Alfaro.
Another close-range stop by Coltorti thwarted Juanlu, but the keeper could do nothing about Roman's stoppage-time header. Ricardo crossed from the right and Roman met the ball at the far post, heading back across Coltorti and into the top corner.
The pressure continued after the break, Coltorti again saving quite brilliantly from Juanlu before also holding Ayoze's long-range strike.
Toni Moral shot wide on a rare Racing break, but the hosts doubled their advantage in the 56th minute. Coltorti blotted his copybook by bringing down Alfaro, earning a yellow card in the process, and Ayoze dispatched the penalty into the bottom left corner with his left foot.
Nino shot wide before the visitors shocked the Estadio Heliodoro Rodriguez Lopez by pulling a goal back with 19 minutes to go. Arana played the ball into the box for substitute Xisco to finish low past Aragoneses from close range.
They were unable to push for an equaliser, though, and indeed it was Tenerife who looked most likely to score again.
Coltorti saved from Nino three minutes after the goal and Alfaro's free-kick was off target before a chance in the fifth minute of injury time neatly encapsulated the match.
Nino's effort from the right-hand side of the penalty area forced yet another outstanding parry from the unfortunate Coltorti - whose part in the decisive goal was a cruel quirk of fate amid an outstanding display.
