It's modified usssa, its plate and mat for a strike, staring 1-1 count. Pitches must be above the battered head and no higher then 12 feet. No fakes, jukes, or windmill pitching. Depending on the division, single A 1 homerun until the other team hits 1 then you can hit another. Just an out of you do hit one. AA gets 3 and then 1 up. Balls are 44/375 weather next week is supposee to be 90's during the day and 70's at night. Pm me if u need more info
