In softball is the first basemen allowed to stand right on top of the base when a runner is running to the firstbase?

Answer 1

Yes, however it is not recommended because if the first basemen is on the base while the runner is running and the runner runs into the first basemen there will be no calls made on interference and injury is very possible.

This is why you have the orange/white double first bases in youth softball. The first baseman can actually be called for interference if they are blocking the white base in youth softball just as they can for blocking second or third.

Answer 2

The second baseman stands in the infield area between first and second base. He or she can play as close or as far from second base as necessary, but is responsible for getting any balls that come between the first baseman and second base. He or she also stands in towards home plate, or out towards the outfield depending on the runners on base or the type of batter.

Answer 3

Only if he is intending to tag the runner instead of stepping on the first base bag.

Answer:

It depends on the situation. A defender cannot block a runners path just to be doing it, however if a defender is making a play on a batted ball then the defender has the right to field the ball and if the runner makes contact with him even if he is in the baseline the runner can be called out (more then likely will be called out for runner interference). If the defender is making a play on a thrown ball or a tag then if the 1 basemen "gets in the way" of the runner there is nothing illegal there either.
