Baseball umpire Jen Pawol made history Saturday in Atlanta as she became the first woman to umpire a Major League Baseball regular season game.

One could say Jen Pawol earned the greatest compliment an umpire could get: Aside from her trailblazing debut, you'd have hardly noticed her.

Pawol's rise to make MLB history came 28 years after the NBA gender barrier for game officials was broken and 10 years after the NFL hired its first full-time female official. The men's soccer World Cup first hired a female referee three years ago. The NHL has not had any women as on-ice officials.
