Most of his 13-year professional career was spent with Mallorca, with which he appeared in 330 competitive games and won two major titles.
Born in San Sebastián, Gipuzkoa, Olaizola's first professional club was SD Eibar in his native Basque Country, in the second division. Subsequently he played two seasons with Real Burgos CF, going on to suffer two consecutive drops and returning for a second spell with his previous team afterwards.
In 1995 Olaizola signed with RCD Mallorca, immediately becoming an undisputed starter as well as team captain and helping the Balearic Islands side to the 1998 Spanish Supercup against La Liga giants FC Barcelona, as well as a second place in the following year's UEFA Cup Winners' Cup. His first and only goal in the top flight – and overall – came on 17 December 2000, as he scored a last-minute equalizer at Celta de Vigo (2–2).
Olaizola played only 27 matches in his last two years combined, due to several injuries and age, and retired at almost 35. He then had brief spells as manager, with Mallorca's youth teams and Antiguoko (also a youth club, in the Basque region).
