Gorostiza was born in Santurtzi, Biscay. He played youth football for Chávarri de Sestao and Zugazarte, making his senior debuts with Arenas Club de Getxo and Racing de Ferrol (one season apiece) before signing for Athletic Bilbao in 1929. He made his La Liga debut on 1 December 1929 against Real Madrid, and scored 37 league goals in his first two seasons combined (in 36 matches) as the club won back-to-back national championships, adding as many Copa del Rey trophies.
Gorostiza was a member of an Athletic attack that also included Bata, José Iraragorri, Chirri II, Lafuente and Víctor Unamuno, being coached by English Fred Pentland and winning two Pichichi awards with the club. He scored the last goal in the 1933 Spanish Cup final, a 2–1 victory over Real Madrid in Barcelona.
During the Spanish Civil War, Gorostiza played with the Euskadi XI, a team which was put together at the suggestion of José Antonio Aguirre, the president of the Basque Country and a former Athletic player. The side went on tour to raise funds for the Basque cause and played in Europe and Mexico, even entering the Mexican league during the 1938–39 campaign, although by then Gorostiza was no longer with the squad.
Valencia / Later years
On returning to Spain, Gorostiza returned to Athletic as they attempted to rebuild their squad using younger players, featuring in the 1939 Copa del Generalísimo and the full 1939–40. He then joined Valencia CF as the young Che squad had managed to remain intact during the conflict and now, aided by the veteran (31), eventually won two leagues and one cup, with the player netting in double digits in four of his six seasons, with a best of 20 goals in 24 games in 1941–42.
After leaving the Mestalla Stadium, Gorostiza played for Barakaldo CF during the 1946–47 campaign, in Segunda División, and then retired at the age of 38. However, he twice came out of retirement, with CD Logroñés and Juvencia Trubia, finally calling it quits in 1951.
While at Athletic, Gorostiza made his debut for Spain, appearing against Czechoslovakia on 14 June 1930. He represented the nation at the 1934 FIFA World Cup, playing in the 3–1 win against Brazil and the 1–1 draw against Italy; he missed the replay against the latter, a 0–1 defeat.
Gorostiza began to struggle with alcoholism while still playing, and this eventually led to severe economic problems. He was found dead by a nun on 24 August 1966 at the Santa María en Santurce nursing home in Bilbao, aged 57.
