The same as in Major League Baseball and all levels of the game from high school on up.
Yes, most high school leagues require -3, but rules can be different from league to league.
No, they are completely different leagues... in louisiana, high school baseball is part of the Lhsaa, usssa is a recreational or tournament league
It is a different number every year. It all depends on the talent level.
A high school batter's box dimension is â?¢4ft x 6ft and 6 inches from home plate. Each league has different dimensions for each part of the field.
Ball hardness. Little league balls are "softer" than high school balls.
No connection. Have to be real good at baseball
4 feet by 6 feet
In Texas, I believe Middle School uses a 70-foot diamond...same as PONY.
Around 80% play High School ball.
