I guess if you were to call it something it would be called advancing bases, or if the coaches were talking about the runner it would be called advancing the runner.
NO
A runner doesn't get a strike, a batter does.
Anytime the batter is put out at 1st base on a batted ball it is not considered a fielders choice, it is simply a put out. Now in your scenario if the catcher would have thrown home and the runner coming from 3rd is out and the batter is safe at 1st, then in that case it would be a fielders choice
no. the only way to get out while base running is: if you get thrown out. if you get tagged out. or, if you lead off before the pitcher has released the ball.
NO
yes they can I play High school softball and you can get but if you leave the base before the pitcher releases the ball you are out
If the runner gets tagged, then he is out. If the base doesn't get stepped on or the runner gets tagged, then he is safe.
No hit it is a fielders choice
The batter is out, if they hit a ball in the air and a defensive player catches the ball before it touches the ground, in fair or foul territory. If a defensive player has the ball in control and touches a base before the runner, the runner is out. If a defensive player has the ball in control and touches the runner with the ball in their hand or glove, the runner is out.
Yes, runner cannot intentionally dislodge ball from fielders glove.
A sacrifice fly in softball is when they batter sacrifices themselves (meaning they are getting an out) to score the runner or to move the runner into scoring position.
It's called a force. The runner is being forced to proceed to the next base by the batter/runner.
