Pitching from the windup like almost all of the major league pitchers do makes pitches much tougher to hit than pitching from the stretch. Why? There is more deception in their delivery, which means they can hide the ball longer and stop the hitter from picking up the pitch too quickly, which enables hitters to make adjustments in their approach if they see early what kind of pitch is coming.
Pitchers also throw harder from the windup because it provides more momentum and leverage to create power and hand speed, the essential components for velocity.
Since many youth baseball coaches don't teach windups, most youth pitchers throw from the stretch. As a result, a pitcher's development is slowed and it will be impossible for these pitchers to reach their full pitching potential. They also fall behind other players who were taught the windup correctly and will lose out on future baseball opportunities.
To correctly teach the windup, every element must be effectively taught from the initial pivot to the leg lift and stride, through pitching plate pivot and front foot landing, upper and lower body mechanics, arm slots, and the follow-through.
Youth baseball coaches need to research pitching. They can watch big-league pitchers and learn from their technique. Coaches can also ask experts to improve their pitching knowledge through baseball coaches clinics and seminars.
If youth baseball coaches follow this advice, they will help their pitchers and their team be successful.
