Batter cannot completely leave the box unless the ball is replaced. Or simply put a 15sec pitch clock that starts once the pitcher gets the ball back in his glove. 25 seconds if the ball was replaced so they can re apply resin. Batters and pitchers must follow. If it is the pitchers fault that the time passed a ball is added. If it is the batters fault it is a strike. I hate watching every single pitch the batter steps out to revelcro everything, spit 4 times, adjust the cup, kick the dirt 3 times and step one foot in adjust the helmet spit 3 more times then fully come in. That takes a good 30-40 seconds i cant stand it.
