He toiled around in the minor leagues for another seven years until 1984 when he called it quits after spending the last seven years in the
California Angels organization. Mangual's career minor league numbers were good, a .268 average with a .391 on-base percentage and 161 home runs and 303 stolen bases. ==Personal life==
