This is a great outfield drill to help with timing and sequencing your throw trying to get a runner out at a base or home. Similar to throwing the ball up and hitting it yourself with a bat, creating timing and barrel, throwing the ball up to yourself, allows you to demonstrate various types of foot work in order to make an efficient, dynamic throw. Working on power drives, pro steps, shuffles, and all sorts of variations will help you become a more athletic outfielder! Great work at @sixfou
