Marbella can no longer boast being the best home side in the division after losing that honour in controversial fashion on Sunday afternoon.
Badajoz inflicted Los Blanquillos' first home defeat of the season, and their second in a row overall, with a 1-0 scoreline.
A single goal from Ruano was the difference, scored in the seventh minute from the right wing; the forward chipped the ball over Wilfred into the far corner with his weaker left foot when everyone was expecting a cross. but
Ruano, though, not only took centre stage for his brilliant attacking performance, but also for his role in the greatest controversy of the match.
With Marbella chasing the game, Ruano received a second yellow in the 87th minute - a moment which could have changed the outlook of the tie. However, it wasn't until the 94th minute that referee Arias Madrid realised his error and gave the forward his marching orders.
With Badajoz making it over the line with their three points intact, the decision makers at Marbella are now pondering what action, if any, should be taken in light of the dropped points.
