Rule 4.09. A run scores when a runner touches home plate before the third out is made, EXCEPT that no run can score when the third out is the result of a force play, or when the batter is put out before touching first base.

The batter being put out before he touches first is NOT a force out. It is just an out, but, if it is the third out, no runs can score. Many people believe that a FORCE OUT is any play where you can put out a runner simply by touching a base. This is NOT correct. Many people think that when you tag the runner instead of stepping on the base that the runner was forced to; that this is not a force-play. This is also NOT correct.

A FORCE PLAY is in effect anytime a runner is forced to leave his base because the batter became a runner. It doesn't matter how the runner is put out; a tag, an appeal or stepping on the base; in all three cases the out is a FORCE PLAY. Whenever the batter is put out in any manner, all forces are removed. There are three types of plays where touching the base is all that is required.

1. When a runner must advance because the batter became a runner. (This is always a FORCE play)
2. When an appeal is made that a runner missed a base while advancing or retreating. (This could be a FORCE PLAY if the base being appealed is one to which the runner was forced to advance. Otherwise it is not.
3. When an appeal is made that a runner did not retouch (tag-up) after a fly ball was caught. (This is NEVER A FORCE PLAY)

Rule 2.00 which contains definitions is an important part of the rule book. Many people do not understand what a force play is. A FORCE PLAY is a play in which a runner legally loses his right to occupy a base by reason of the batter becoming a runner. This means anytime a batter is put out before reaching first base ALL forces are off. If a following runner who was forced to advance is put out, the force on the preceding runner is removed. Confusion regarding this play is removed by remembering that frequently the "force" situation is removed during the play. Example: Man on first, one out, ball hit sharply to first baseman who touches the bag and the batter-runner is out. The force is removed at that moment and the runner advancing to second must be tagged. If there had been a runner on third or second, and either of these runners scored before the tag-out at second, the run counts. Had the first baseman thrown to second and the ball then been returned to first, the play at second was a force out, making two outs, and the return throw to first ahead of the runner would have made three outs. In that case, no run would score because the batter made the third out before reaching first.

Example: NOT a force out. One out. Runner on first and third. Batter flies out. Two out. (All forces are now removed) The runner on third tags up and scores. Runner on first tries to retouch before the throw from the fielder reaches the first baseman, but does not get back in time and is out. Three outs. If, in the umpire's judgment, the runner from third touched home before the ball was held at first base, the run counts. The above two paragraphs are from the rule book. In the example above, you must understand that the batter was out on the catch. That removed any force play by definition of force play. The attempt by R1 to return to first after the catch is NOT a force play. It is an appeal play and for scoring purposes a TIME play. People frequently make the mistake of saying he is forced to tag up, thereby thinking it is a force play. The proper statement is; he must retouch. But, any play on the attempt to retouch is NOT a force play, because the batter has been put out.
