What separates good athletes from elite performers? It’s not just talent—it’s mental discipline. In this episode of Most Valuable Agent, Sean Casey, former MLB All-Star and performance coach, breaks down the mental game of baseball and how mastering your mindset can transform your performance on and off the field.

Sean shares how Harvey Dorfman’s book, The Mental Game of Baseball, completely changed his approach to the game, giving him a sixth tool—the ability to stay calm, focused, and confident under pressure. He reveals how mental toughness helped him go from being overlooked in high school to becoming one of the best hitters in the country.
