It's called a "grand slam."
In baseball a "point" is called a "run" One home run with no runners on base counts as 1 run. If there are runners on base each runner is counted as 1 additional run. There cannot be more than 3 runners on base. If a home run is hit with 3 runners on base the home run counts as 4 runs. Also when a batter gets a homer, the batter also counts as a run. EX: Runner on 1st, home run would count as 2 runs!
A home run is worth one point plus the number of runners on base. If there are no runners on base, it is just one point. If the bases are loaded, it is four points and is called a "grand slam".
When ever the home run rule was made. A grand slam is just a home run with runners on every base.
On a Home Run, the runner is still required to touch all bases, even if he is entitled a run. If he misses any base, including Home Plate, and makes no attempt to return to the base to touch it, he will be declared Out and his run does not score. If other runners are also running and touch all of the bases, their runs will score. If there are two outs with runners on, only the runners who crossed the plate before his run would score.
4 runs would score: the 3 runners on base plus the batter who hit the home run. Grand! Slam!
if the ball is hit out of the park and he gets called out because of that then the runs are forced in beause it was a home run
In general, if there are base runners, the pitcher should run to cover home. If there are no runners on, the pitcher can just stay on the mound.
A grand slam is 4 runs. 3 base runners and the hitter himself get to cross home plate.
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.
There is no 4th base. There is Home "Plate".
Actually, a force out in Softball is, for example: If runners are on first and second, the force out is at third because the runner is forced to run to third base due to the runners behind him/her.
All runners on base move ahead one base. The runner on third scores when he touches home plate. The batter gets an RBI. The pitcher may be charged with an earned run depending on how the runners got on base.The pitcher gets upset with the umpire.
