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
