Spinks won seven games as a big leaguer, pitching for the Houston Astros and St. Louis Cardinals from 1969-1973. He pitched in just 11 games for the Astros during the first three years of his career but appeared to be on his way to a breakout season with the Cardinals in 1972. He was 5-5 with a 2.67 ERA and 93 strikeouts for St. Louis before he injured his knee in a collision with Johnny Bench at home plate. The injury ended his season and, for the most part, his career. He attempted a comeback in 1973 but went 1-5 with a 4.89 ERA. He stuck around two more years in the minor leagues before retiring in 1975.
Spinks became a pitching coach following his playing career. He is currently a scout for the Arizona Diamondbacks. The book he mentions, Little League to the Major Leagues, is available here.
