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.
A fly ball that advances a runner from second to third is not counted as a sacrifice fly, and it does count as an at bat. Unless a runner scores on a fly ball, the batter is charged with an at bat.
That would depend on how the runner was retired at second base. For example, if the runner slipped and fell on his way to second base and the outfielder had the time to throw him out on a force play, the batter would not get credited with a base hit. If the runner made it to second base safely and then slipped rounding the bag and the outfielder threw to second base and the runner was tagged out, the batter would be credited with a base hit. If a runner is forced out at any base, regardless of where the ball was hit, the batter is not credited with a base hit.
Runner attempting a steal from first, or a runner caught returning to second base.
No. In no situation can a batter be credited with a base hit if a runner is forced out.
No hit it is a fielders choice
returned to first because when the batter intefer with the catcher the play is normaily stop
Catcher pop time is the time it takes for a catcher to come out of his crouch after receiving the pitch (like if he was going to try and throw a runner out at second base).
Yes it is considered a sacrifice.
YES he can be called out on an appeal... this would be the same as if a home was hit and the runner had not tagged first base ...
