The San Sebastian-born guy saved shots from former teammate Alexander Serlot and the man who brought Atletico Madrid to overtime, Julián Álvarez, in the first two series, thus guiding the "white-and-blue" towards their first trophy since 2020.
Juan Musso also saved Ori Stein Oscarsson's shot in the second series, but everyone was scoring until the end, so Sociedad, like in 1987, defeated Atletico in the final after a better penalty shootout.
This is Pellegrino Materazzo's first trophy in his coaching career, but also a real reward for both him and the club's management, which made a somewhat unexpected move when it brought in the American expert on December 20th.
Sociedad took the lead in the 15th second with a goal from Ander Barenecea, only to be equalized in the 19th minute by Ademola Lukman.
Mikel Oyarzabal gave the Baks a new lead at the end of the first half, and Alvarez brought extra time with a brilliant goal in the 83rd minute.
In the 100th minute, Pauk hit the crossbar with a phenomenal shot, but there were no goals in extra time.
For the club that won the Copa del Rey for the fourth time in history, Carlos Soler, Luka Sučić, Ajen Muñoz and Pablo Marín scored the penalties at the end, while Nico Gonzalez, Thiago Almada and Alex Baena were accurate for the "quilters".
