Jen Pawol is set to become the first woman to umpire in Major League Baseball when she works games this weekend between the Miami Marlins and Atlanta Braves.

The league announced that umpire Jen Pawol will be working the three-game series, making her the first woman in MLB history to umpire regular-season games. She will be working the bases during Saturday's doubleheader before taking the position of home-plate umpire in Sunday's series finale.

Pawol, 48, began her affiliated-baseball umpiring career in 2016 at the rookie-ball level. She reached the Triple-A level in 2023, and then in 2024 she became the first female ump to work a spring-training game since Ria Cortesio in 2007.
