Steve Blass abruptly loses his control
Steve Blass, the Pittsburgh Pirates pitcher who won two complete games in the 1971 World Series and 19 games in 1972, suddenly became unable to throw strikes in 1973, walking 84 batters in 88 innings with an ERA near 10. Mechanical fixes, psychological theories and minor-league stints all failed, and he retired in 1975 still physically healthy. Angell presents the case as a mystery with no villain and no cure, and uses it to show how fragile an elite skill is and how little anyone understands about why it fails.
