Yes, it is coach's interference if, in the judgment of the umpire, the base coach at 3rd base, or at 1st base, by touching or holding the runner, physically assists him in returning to or leaving first or third base.
The base runner can not advance on a foul ball, he must return to the base he was at before the foul ball was hit. A base runner may advance on a caught foul ball, but must tag up and advance only after the ball is touched by a defensive player. To answer your original question, yes, all base runners must return to the base they occupied prior to the foul, and must touch that base before play is continued.
Runner is out. No. The rule reads the runner is out if physically assisted by the coach. Simply touching the runner is nothing.
If it is a force (i.e. there are people on all the bases behind the runner) play, then yes, the baseman needs to touch the base to get the runner out. If the runner is not required to move to that base, then the baseman must tag the runner to get him out. The baseman does not NEED to touch the base to record the out. The defense may tag the runner OR the bag.
As long as the coach does not assist the runner, there is no penalty.
yes the batter must touch the base or he will called out
The 1st base coach can never be out of the coach's box. The 3rd base coach can only be out of his box when the ball is hit and there is a runner on or advancing to 3rd base.
The second runner can, assuming he hasn't crossed in front of the lead runner. If he does that, they are both called out.
Yes. No problem. However, a base runner can neither pass another runner nor may he assist the other runner in running the bases.
Yes, because the hitter is running to first base. If you are still there, you'll both be on a base. That means you are both out. Both runner and batter are not out. The fielder will need to tag either 2nd base for the force out or tag both players occupying 1st. If both players are occupying 1st and both are tagged while standing on first the runner that should have gone to 2nd will be out.
NO, a runner does not have to go back and touch the base after every pitch
If the runner gets tagged, then he is out. If the base doesn't get stepped on or the runner gets tagged, then he is safe.
Yes. He must tag the base.
No. To force an out, the defensive player has to touch the runner with the ball or touch the runner with the glove while the ball is in the glove. A thrown ball touching a runner does not count.
When there isn't a runner behind them forcing them to run. For example, if a runner is on 2nd base but there is no one on 1st base, the runner must be tagged on their way to 3rd in order to get them out. However, if there IS a runner on 1st, the 3rd baseman can simply touch the base because it is a force out.
yes it is a hit, but they can still be out if a defender taps either the base or the runner before he can "get safe" on base. It's the same thing as if a runner hit a bunt, they can still get out until they actually touch the base.
No, the fielder does NOT have to touch the base before tagging a runner out. The fielder only touches the base on a forced play.
No. You can't even touch a base out of order. If you pass a runner (and touch the next base before he does) you are out.
The pitchers mound
No the base coaches should never leave the box, it may cause interference and make the base runner out.
