The MLB is taking hazing seriously.

FOX's Chris Hoenig reports:

Included in Major League Baseball's new collective bargaining agreement is a policy that prohibits players from requiring, coercing or encouraging players from, "dressing up as women or wearing costumes that may be offensive."

Representatives for the players union saying that times have changed and players need to be more conscious of how they conduct themselves at all times.
