why do baseball coaches and managers wear uniforms?

They want to show that they are part of the team.  It was tradition for managers to also play for their teems at the same time they coached them.  Also MLB rules state that only uniformed players are allowed on the field.  (From MLB rule 3.15: No person shall be allowed on the playing field during a game except players and coaches in uniform, managers, news photographers authorized by the home team, umpires, officers of the law in uniform and watchmen or other employees of the home club.)

Almost all managers outside of Connie Mack and for awhile John McGraw all managers have worn uniforms.   However back in the late 1800's and early 1900's the managers were almost always playing managers, but if you look at pictures from the 1910's and 1920's you will usually see the managers in uniforms.

Sometimes during warmup or training the managers step in and show the players what they want them to do.

They change balls really often.  It's because they're worried about the ball being scuffed or damaged during the game.  The ump wants to ensure that the game isn't swayed in favor of either team.

The top ten players coaches are usually on a salary and they get performance bonuses on how well they do in the majors.  A contract is usually drawn up to protect both player and coach.  The bonuses are usually in the ten percent range.

in order for the "docs" to wear Marine regulation uniforms they have to go completely "green side". which means that they have to conform to all Marine Corps regs. so yes some corpsman do wear and some dont.

It's the pine tar players use for their bats for better grip...it gets on their helmets everytime they adjust it, take it on, take it off...some playesr likd vlady use the same helmet every year, game in and game out so it looks pretty nasty...like Trot Nixon of the red sox, and ozzie guillen used to do the same when he played

The manager doesn't have to wear a uniform, but must be wearing a uniform if he wants to go on the field to talk to the pitcher or for whatever reason to be on the field.

On top of what the previous two just said they often also help to manage the personnel during a game.  In other words they would give the manager advice on player moves and also take care of the lineup card and know who is eligible to play that is on the bench, thus they are the "bench" coach.

I think that the dress code is a little out of control. However, I do understand why it was implemented. I mean these dudes make millions of dollars a year, and they show up to a game in a white t-shirt and some jeans.... I think that the sanctions included in the dress code are a bit too strict. I don't feel like the players should have to dress up in a suit and tie. A casual but professional look would have been just fine.

coaches always try to make a combination as batting line ups as in fielding too. just becuz every player know his role in field and when he field in ground they could not feel any type of difficulty or uniqueness at their place

Because they're wearing a cup, and cups aren't all that comfortable.  Now, with that said, I guess baseball players just have less self-restraint than football, hockey, and soccer players.

As a Boston Red Sox fan I know all to well about being superstitious/quirky, it even carries over to hockey. On days that the stars play I always wear my very thin framed eye glasses over my regular pair, and when I go to a stars game in person I wear the green stars jersey opposed to the white jersey from the early 90s when they first arrived in Dallas. In fact when I go to games I keep track of the W-L-OTL record of who I go with (if its a bad record they won't be going to playoff games) And finally at games I wear my Boston Red Sox cap with the two sox on the back of the cap and when the stars need a big goal I rub the two sox for luck (I do the same thing in baseball when Boston needs a big run).  I don't have a playoff plan yet as they are still a few months away and I have learned the best plans are the spontaneous ones.

If you're on the team then there is nothing wrong with asking the coach why you don't have your uniform.  He may have just forgot!  If he does snap at you when you ask and he doesn't give you one, then he's a bad coach.

Under Armour is designed to maximize effectiveness of the wearer by either keeping them cool or warming them up (depends on weather).  In baseball you'll see people wear Under Armor or an equivalent during the cooler months to stay warm. Football players more and more are starting to wear the cool product during the early season to stay cool.\n\nAll in all, its an overpriced article of clothing to keep the wearer comfortable in hot or cold weather.
