yes, he trying to tell him/her goodjob or telling them what to do
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.
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.
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.
yes the batter must touch the base or he will called out
As long as the coach does not assist the runner, there is no penalty.
Yes. No problem. However, a base runner can neither pass another runner nor may he assist the other runner in running the bases.
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.
NO, a runner does not have to go back and touch the base after every pitch
