Marbella consolidated their play-off position in Segunda B with an exhilarating last-minute triumph over Yeclano on Sunday.
Óscar got his sixth of the season when he expertly controlled a long ball with his chest and beat the goalkeeper with a fine finish from a narrow angle.
The visitors got themselves back into the game with a wonderful chip from Tonete before half-time, but the second half was all Marbella's, and a last-minute bullet header from Manuel Martínez won it for the hosts.
The result means that David Cubillo's side remain the only unbeaten side in Spain this season. They are currently in third place, only three points off leaders Cartagena. Their next match is a tough away trip to fourth-placed Badajoz on Sunday.
