Substitute Sergi Darder fired Real Mallorca into the Copa del Rey final in a dramatic penalty shoot-out at Real Sociedad.

The visitors scored all five of their spot-kicks after Mikel Oyarzabal had missed with the hosts’ first attempt to book a showdown with either Athletic Bilbao or Atletico Madrid, who meet on Thursday at the San Mames Stadium with Bilbao defending a 1-0 first leg lead.

Mallorca, who sit in 16th place in LaLiga, had taken the lead at the Reale Arena through Giovanni Gonzalez’s header after keeper Dominik Greif had saved Brais Mendez’s penalty but Oyarzabal made it 1-1 to take the tie into extra time, only to be found wanting from 12 yards.

Mikel Merino, whose late strike sealed a 2-1 league win at Mallorca earlier this month, failed to repeat the dose when he fired high and wide with eight minutes gone, but Dani Rodriguez was no more accurate at the other end five minutes later.

Arsen Zakharyan forced a save from distance as the home side pushed for a breakthrough, but Abdon Prats went close for the visitors six minutes before the break.

However, seventh-placed Sociedad were presented with a golden opportunity to open the scoring at the end of the first half when Antonio Raillo was adjudged to have handled in the area, only for Greif to save Mendez’s spot-kick.

It was the visitors who took the lead five minutes after the restart when Gonzalez headed home from Jaume Costa’s cross.

The goal prompted something of an onslaught from the hosts which finally paid dividends with 19 minutes remaining when Oyarzabal equalised from Mendez’s through-ball.

Fellow substitute Sheraldo Becker almost won it for Imanol Alguacil’s men with 10 minutes left on the clock, but neither side could find a winner as time ran down.

The home side created the better chances in extra time, with Greif saving from Becker and substitute Umar Sadiq, but the teams could not be separated and penalties were required.

Oyarzabal was unable to convert the opening spot-kick in the shoot-out and with Vedat Muriqi, Manu Marlanes, Omar Mascarell, Nemanja Radonjic and Darder all successful for Mallorca, they ran out 5-4 winners.
