When writing or "doing the official score book", when a runner is tagged out, the number designated by the field position (so pitcher would be 1, catcher would be 2, ect...) with the letter "U" would be the correct notation. So for instance if the 2nd baseman would to tag a runner going from 1st to 2nd base the notation would be 4U. Meaning second baseman unassisted.
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.
If the first baseman tags first base, the runner originally on first is therefore not forced to second base and he is safe at first.
No, in that situation the person with the ball would have to tag the runner for the runner to be out.
yes it is a force out
Yes as long as the runner advances Assuming you mean the runner tags up on a fly ball and advances to second, it is not scored as a sacrifice, but, simply as a fly out and the batter is charged with a time at bat. If the batter bunt a ground ball, the runner would not be required to "tag up" to advance and the batter would be credited with a sacrifice. If the batter is attempting a sacrifice bunt and pops up and the runner, tags up and somehow advances to second the batter is not credited with a sacrifice.
Only if a member of the other team tags him.
Runner would advance a base but if appealed that runner could be out.
He needs to catch it, and if he drops it the runner doesn't need to tag up.
The runner would be safe. This is the same as if the ball were dislodged and falls out of the glove.
yaa
Yes. On a tag play, if a runner crosses home plate before another runner is tagged for the third out the run counts.
Yes they would be out, that's if its seen by an umpire. They don't do video for things like this so its a tough call.
