Palacios began his professional career in the Mexican League in 1983 for the Rojos del Águila de Veracruz.

He became a free agent after the season, signing with the Padres. He made his final major league appearance in May 2000, and was released that August. He was picked up by the Chicago Cubs, finishing the year with the triple-A Iowa Cubs.
