Born in Pontevedra, Galicia, Pasarín started his professional career with Celta de Vigo. One of the club's first captains, he played in the team's first ever official tournament, the 1923 Galician Championship, which ended in conquest.
During six seasons Pasarín played in La Liga with Valencia CF, created precisely after he left Celta. His best individual season was in 1932–33 as he played in 17 games, but the Che could only rank ninth out of ten clubs, narrowly avoiding relegation; after retiring in 1935 he worked in the Ministry of Labour, but returned shortly after to play for amateurs Nacional de Madrid.
After the Spanish Civil War, Pasarín obtained his coaching license. He was in charge of the national team for one game, then returned to Valencia for the 1946–47 season, leading the club to its third national championship in six years; a runner-up position followed in the following year, trailing champions FC Barcelona by three points.
He was also in charge of Celta during five top flight seasons in two separate spells, and also managed Real Oviedo and FC Porto (Portugal). He died on 17 August 1986 at the age of 84, in Madrid.
