(CNN) — Baseball umpire Jen Pawol will make history this week as the first woman to work as an umpire in a Major League Baseball regular season game, crossing a historic gender barrier.

Pawol has worked MLB games during spring training but her work on Saturday, when she will be in the crew for a doubleheader between the Atlanta Braves and Miami Marlins at Truist Park, will be her first time in the big leagues. The doubleheader required a fifth umpire to be added to the crew, according to a report on MLB.com.

It’ll be the latest history-making moment for Pawol, who became the first female umpire in 17 years to work a spring training game in 2024. She was the seventh woman to umpire in the minor leagues and made her pro debut in the Gulf Coast League in June 2016, according to MLB.
