Marbella's poor run was extended to six consecutive matches without a win on Sunday as they gave up another two points in the closing stages of the game.
The first half was very even as both sides created a number of decent chances for themselves. San Fernando looked particularly threatening early on. In the 17th minute, forward Espinar beat a Marbella defender with a nutmeg to find himself in front of Marbella keeper, Manu, whose block rebounded the ball back to Espinar's head, which fortunately for the visitors, went wide. A similar chance came in the 19th minute as centre-half, Rubén, had another clear header in front of the Marbella goal.
However, just two minutes later, the hosts also faced potent efforts from Marbella's forward Pedro Mérida, and from Kike Márquez in the 36th minute, but the San Fernando keeper, Salva, performed equally impressive saves.
The high intensity persisted throughout the first half but neither team could find that bit extra to break the stalemate.
In the second half, however, Marbella were indisputably the better side, making the eight places that separate the teams in the Segunda B table apparent. The players had only just returned from half-time when Kike Márquez had another great chance. From then onward the visitors dominated, with the occasional intervention from the hosts, until finally in the 70th minute, an unstoppable shot from Andrés Sánchez, in the front of the area, put the away side ahead.
Subsitute striker Ebú had the best chance to seal a win for Marbella in the 93rd minute after making an impressive run to find himself in a one-on-one with Salva. However, consistent with their recent form, the visitors could not withstand the counter-attack that followed and San Fernando's Lolo Garrido punished them for their defensive errors in the last minute.
Despite the fixture's disappointing conclusion, Marbella stay in fourth position and therefore retain their position in the playoffs.
