Legit smallest zone ever. Meanwhile the great Grudz makes the starting pitcher and catcher have to fight their own battles. Same crap he pulled last year. He is a horrible manager.
As for Kopech, it's easy to see where the struggles with command have happened. When he stays on top, his command isn't bad and velocity around 96. When he tries to throw up in the zone, he gets under the ball and its way high and out of zone and velocity around 92-94.
