An original Padre, Nate Colbert, was plucked from the Houston Astros in the Expansion Draft. 

Colbert became the Padres starting First Baseman, and while he was not the best contact hitter, he was good with the power aspect.  Over his first five years in San Diego, Colbert hit at least 22 Home Runs, with seasons of 38 in 1970 and 1972.   Colbert was an All-Star three straight years (1971-73) and finished eighth in MVP voting in the middle year.

Back problems reduced his effectiveness, and after a poor 1974 season, he was traded to Detroit.  Colbert accumulated 163 Home Runs with the Padres.
