The letter, sent May 20 by MLB senior vice president of on-field operations Michael Hill to general managers, assistant general managers and some ballpark-operations staff, highlighted the issues a wide array of women - including coaches, trainers, analysts, translators, mental-health professionals, massage therapists, player-development employees and others - face because of substandard facilities. In a pointed letter to teams last week, Major League Baseball said numerous clubs' stadiums 'fall embarrassingly below the high standards' necessary for women who are part of the game's traveling parties to do their jobs, create an 'untenable working environment' and that organizations soon must reconfigure their facilities to fix what the league deemed 'unacceptable,' according to a copy of the memo obtained by ESPN on Thursday.
