    The NFL became the second of the four major U.S. sports leagues to hire a female full-time official in April. Thomas, 42, started with high school games in Mississippi in 1996. Fifteen years later she was the first woman to officiate a college bowl game. She also worked NFL preseason games and scrimmages. "The guys don't think of me as a female. They see me as just another official," she said when she was hired.

    Justine Siegal, MLB

    It wasn't a position in The Show, but Siegal got a chance to put on the Oakland Athletics' uniform this past fall, coaching some of the organization's young prospects. She threw batting practice pitches, worked with infielders on their defensive skills and led classroom presentations.
    She said she hoped that her two-week stint as the first female coach for a major league team would lead to a full-time job with the A's.

It's just about opening doors and opening people's minds," she told CNN. Lieberman is a Hall of Famer and a two-time Olympian. She played in the WNBA's first season in 1997 when she was 39.
