Valencia, who have won just one of their last four matches, went ahead through Tino Costa's deflected shot and doubled their advantage early in the second half when a mistake from Mallorca goalkeeper Dudu Aouate allowed Aritz Aduriz to score.
Whether or not it was change of formation that made the difference, the scores were level a minute into the second half when Edu misdirected his attempt to head clear a TinoCosta free-kick into the corner of the net from all of 15 yards.
