I sent these to Jerry Mumphrey several years ago (mailed 11/19/99 and returned on 4/18/00); Jerry lives not too far from me in Tyler, Texas (home of the Tyler Rose, Earl Campbell).
Mumprey began playing with the Cardinals on September 10, 1974. He would play there until going to the Padres in '80 for one season. He came to Houston in '83 and would stay until '85. He played his last game on September 30, 1988 with the Cubs.
While he was with the Astros he was an All-Star selection (1984).
