New players are to be banned from dressing up as women, as part of Major League Baseball’s anti-bullying policy.<\/p>\n
Other prohibited costumes include those that are “offensive to individuals based on their race, sex, nationality, age, sexual orientation, gender identity or other characteristic”.<\/p>\n
Superhero costumes such as Batman and Spiderman are still allowed.<\/p>\n
The annual dress up day is a tradition for rookies in an initiation practice called “hazing”.<\/p>\n
In September, the New York Mets posted photos and video of players wearing uniforms from the All-American Girls Professional Baseball League, as portrayed in the 1992 Hollywood movie “A League of Their Own.”<\/p>\n
