Baley was a goalkeeper in Argentina's 1978 FIFA World Cup winning squad and also in the 1982 tournament. Given goalkeeper Ubaldo Fillol's consistent performances, he ended up playing only a few matches for the national team.
In 1978 Baley was part of the Independiente team that won the Nacional championship of 1978.
He also played for Huracán, Colón de Santa Fe, and for Talleres de Córdoba, where he was badly injured during the last game of the 1982–83 season (the game that handed the championship to Estudiantes, the team he started his career with). His replacement in that game was Ángel Comizzo, who made his debut.
