The Mexican attacker scored an invaluable stoppage-time winner to lift Mallorca to a 1-0 result over Celta de Vigo, providing three points for the club that currently sits in the Spanish drop zone.
Dos Santos pounced on a saved header to touch home a rebound in the 93rd minute and spark wild celebrations at Iberostar Estadio when it appeared that the club would have to settle for a single point against last-place Celta.
The win pulls Mallorca out of the Liga cellar and on 27 points, level with 18th-place Real Zaragoza (but behind on goal differential). The two teams will clash at Mallorca on April 27, and both clubs are within one point of safety, as Granada sits in 17th place with 28 points. Deportivo La Coruna is also within reach, in 16th place on 29 points.
For Dos Santos, who started the match, the goal was his fourth of the season. He picked up a yellow card for ripping off his shirt in celebration, but it's a caution he'll happily accept considering the possible ramifications of his goal, which helped snap a three-game losing streak for Mallorca.
