How come Mlb teams dont shake hands with each other after each game and say “good game” like little league?

Little Leagues teams do it all the time after games,Also when I used to play junior league baseball we shook hands with the other team and made a shaking hands straight line.How would baseball players feel if the mlb commissioner made a rule that "teams should shake hands with their opponent everyday after each game or they will get suspended for unsportsmanlike and not giving respect"Its like little leagues do it.If I was the commissioner I will make that rule.IT SHOWS RESPECT

I need a Slogan for a Baseball Tshirt im Making?

At my high school there are girls that support the baseball team and each have a specific baseball boy that they buy treats and things for before games and make them scrap books at the end of the year.
We are making tshirts to support them and we wanted a cute or funny saying for them
we are also selling baseball tshirts for a fundraiser and need a slogan that ANYONE could wear.
Help would be greatly appreciated :]
our mascot is a maverick, but you dont have to use that.

When did New Era put the MLB logo on the back of their 59Fifty caps?

The 59Fifty is the premier hat for the New Era Cap Company. It is the same cap worn by MLB players and coaches during games.
