Major League Baseball has certainly seen an evolution in terms of coaching over the past several decades. With the advent of modern technology, the birth of sabermetrics and the development of bullpen specialists, the need for more advanced coaching was necessary.
Pitching coaches have become an integral component for each MLB team. Managers rely heavily on their assessment of each pitcher and are tasked with the responsibility of working with each pitcher to tweak mechanics, act as a mentor/adviser and in some cases act as a psychologist.
Very few teams employed pitching coaches before the 1960s, and when they did, they were often former catchers. In the book The Evolution of Pitching in Major League Baseball, author William F. McNeil noted that catchers could help out with evaluating a pitcher’s stuff, but not much else. Forty or 50 years later, the pitching coach has become the manager’s “right arm.”
With the evolution of pitching, hundreds of pitching coaches have tried their hand at transforming pitching staffs with varying degrees of success. Each coach is vastly different in their approach, some strong on mechanics, others focus more on game preparation and others with various techniques and strategies developed over time.
