Sarriugarte represented Athletic Bilbao for five seasons – having arrived at the club at age 16 – but only started regularly for the first team in 1986–87, appearing in 99 games for the reserves and scoring 29 goals. He then spent another five years in La Liga with Asturias' Real Oviedo, where he was also never relegated (but only played three matches in his last two seasons combined).
Sarriugarte retired in 1996 at the age of 31 after playing one season with UD Las Palmas and splitting his last year with local Barakaldo CF and UDA Gramenet, all sides in the lower leagues. In the top flight, he amassed totals of 159 games and 28 goals.
Sarriugarte then took up coaching in the early 2000s with the various sides of his first side Athletic. On 8 July 2006, following the dismissal of Javier Clemente, he was appointed first team manager by president Fernando Lamikiz; however, just four months after, he was relieved of his duties, after a 1–3 home defeat against Sevilla FC which saw the club drop into the 18th position, and eventually again barely avoiding relegation.
