Yes they can however not recommend in most instances.
No, unless you don't tell the umpire.
Plays that cannot be appealed are judgment calls. If there is a question about rule interpretation, then the coach should calmly approach the umpire and talk to him about it. Judgment calls are irreversible, even if a bad call was made and it is apparent.
Talk to your local sporting goods companies. Sometimes they'll sponsor leagues or teams to help out in their community. Also, talk to parents of players in your league. Many times parents can have their places of work sponsor teams or leagues.
Yes, but the umpire has the right to shorten the meeting to allow players to reposition without causing a delay in the game.
probably not but you should talk to your doctor
yes
They are looking for hustle and effort. They do not want to see you striking out and waking back to the dugout. They want to see you run to first as hard as you can, even though you are out. they want you to talk to your players, let them know how many outs and where the play is at, etc. They want to see determination, moreso than skill. But a common knowledge of the game is expected.
no you cant it can be a technical foul
With your mouth ....idiot
This is not a requirement, but is done as a courtesy to the catcher. The umpire can also take this opportunity to talk to the catcher and not make it seem obvious. This practice was started many years ago, to be honest, so that the umpire would not show their rear end to the fans primarily behind home plate. Most conversations between the umpire and the catcher occur while both are facing the pitcher (toward centerfield)..that way no fan can see either player or umpire's face, read lips or even tell that an umpire and catcher are talking.
talk to joe williams
No, but you can "talk" to other players...
