I first introduced it in Houston, where it was quickly embraced across hitting, defense, baserunning, catching, and other training domains. Since joining the Cubs, we've brought it into our work again, and it continues to be a simple and effective way to deliver immediate visual feedback—a cornerstone of quality skill development.
