|1920 Antwerp||Team competition|
Sabino gained two caps with Spain, representing the nation in the 1920 Summer Olympics in Antwerp and helping it win silver. His debut came during the tournament in a 2–1 win against Sweden, being immortalized in the annals of Spanish football due to that match: in the play that led to the 1–1 equalizer, José María Belauste, his teammate also at Athletic, reportedly shouted as he requested the pass: "¡A mí el pelotón, Sabino, que los arrollo!" ("Send me that ball, Sabino, i'll crush them!" in Spanish).
Sabino died in Getxo also in his native region on 20 January 1983, at the age of 85.
