When a runner is on a base that a batter or another base runner is required to run to, the former is forced to run to the next base. Two examples and a counter-example:
1) A runner begins the play on first base, and the ball is batted fair. Since the batter is required to go to first base, the runner that began on that base is forced to go to second base, and remains required to do so until the batter is out.
2) Runners begin the play on first base and on second base, and the ball is batted fair. As noted in example (1), the runner on first base is forced to go to second. Thus, the runner that began on second is now forced to go to third base. If either the batter or the runner that began on first base become out, then this requirement is cancelled.
3) A runner begins the play on third base, and the ball is batted fair. The runner MAY advance from third towards home, but is not FORCED to do so. That's because the batter is only required to run to first, and there is no requirement that the runner on third leave his base.
A forced run is when the person must run because there is another runner coming to the base. You cannot have two people on a base so the runner must run. A not forced run is when there is no runner coming to the base so they could stay or the could run.
That depends on whether a runner is forced to vacate a base when a ground ball is hit. If there is a runner on first base and a ground ball is hit, the runner is forced to run to second base because the batter is running to first base. If there is also a runner on second base, that runner is forced to run to third because the runner from first is running to second. If a runner is not forced to run, they do not have to. If there are runners on first base and third base and a ground ball is hit, the runner at first is forced to run to second because the batter is running to first. But the runner on third is not forced to run because no runner is running to third base from second base.
no, you can tag the runner to get him out or on a play where the runner is forced to run you can step on the base he is running to.
FORCE RUN: A runner does not have to advance to the next base unless someone is behind him/her running to the base that the first runner is on. If there is a runner, and you are forced to advance to the next base, it is a forced run. For example, a batter hits the ball and safely runs to second base (making sure to step on 1st base). The next batter hits the ball but only runs to first base. The first runner therefore does not have to run to third base. Now there are two runners on bases and the next hit would make both runners run to the next base. When runners are forced to run, the fielders only have to throw the ball to the next base with somebody catching it. If a runner runs at will (that is not being forced to run), then the fielder must touch the player with ball and not just the base. If not a forced run, you have to tag the runner. If it is a forced run, you tag the base.
A tag play is when it is required to tag a base runner to get them out. A force play is when it is required to have possession of the ball and touch the base to get the base runner out. By definition, a force play is in effect when a base runner is 'forced' to run to the next base because of the ball being hit and another runner being 'forced' to run to the base that the runner currently occupies. If there is a runner on first base and the batter hits a ground ball to third base, the runner on first base is 'forced' to run to second base because the batter is running to first base. In this case, a force play is in effect at second base (and at first base because a batter is always 'forced' to run to first base after hitting a fair ball. A force play is always in effect at first base when a batter hits a fair ball.). If there is a runner only on second base and the batter hits a ball to first base, the runner at second is not 'forced' to run to third base because no one is 'forced' to run to second base. In this case, a tag play is in effect at third base if the runner at second attempts to advance.
yes but they can be tagged on the base if the batter has not been out yet.
It's called a force. The runner is being forced to proceed to the next base by the batter/runner.
No, as long as the runner is forced to go to the next base, they can be tagged out or the base stepped on. Both are considered force plays, which means the run would not count.
No, unless there's is no force play involved. Meaning, you only tag if the runner is not forced to run to next base. But a runner is automatically out once tagged
the fielder must tag the base runner
You can tag that runner with a glove or hand holding the ball, while the runner is not standing on a base.
