Not only in youth Baseball but in all levels of baseball, a closed base means that the next base that a base runner needs to get to has a runner already on the bag.
E.G.: There's a runner on first and second, so a ground ball will force a throw from second base to first base considering that those bases are "closed" with base runners.
In a bases loaded situation, all bases are "closed" because all bases have a base runner and the batter is considered on home plate.
Total Bases
3 base runners on 3 bases
Stolen bases.
bases and the balls they play with lol
in baseball, it means that the bases are loaded.
Well, I think they called baseball, because for base.... their are bases in the game, and for ....ball, their playing with a ball.
If it's an abbreviation for a statistic, it stands for Total Bases.
It could mean a youth was killed or someone was killed by a youth.
I believe you mean "initial sack" and that would be first base.
Youth

it refers to the innocence of youth
