Marbella captain Añón came to his side's rescue at the Estadio Antonio Lorenzo on Sunday as he secured a point for his side with the last kick of the game against San Fernando.
His free-kick in the 94th minute ensured that his team didn't succumb to opponents who had played with ten men for 75 minutes.
San Fernando took the lead in the 14th minute when Hugo Rodríguez tapped home from close range following a free-kick drifted in from the left. Just four minutes later, though, they were down to ten when Sandro Toscano received a straight red for spitting at Óscar García when he was on the ground.
Despite the man advantage, Marbella struggled to get to grips with the league's lowest scorers and went in a goal down at the break.
With the introduction of Juergen for Mustafá, Marbella fought back and quickly got the equaliser when Samu Delgado converted a cross from the left.
With 40 minutes left to find the winner, David Cubillo's side were the strong favourites to win the game. However, things didn't go to plan. With Marbella turning the screw, San Fernando delivered the sucker punch.
A long ball upfield from the keeper was not dealt with by Bernal, leaving former Marbella man Ferrón in a one-on-one with Wilfred. The forward didn't pass up the opportunity and slid the ball under the keeper with just eight minutes left on the clock.
Marbella kept at it until deep into stoppage time when they won a free-kick in a promising position. Seconds after Añón placed the ball into the back of the net, the referee blew up for full time.
The point sees Marbella remain in third place, but the gap to leaders Cartagena is now five points.
