Jen Pawol made history on August 9, 2025, by becoming the first female umpire to officiate a regular-season Major League Baseball (MLB) game. At 48 years old, Pawol debuted as a base umpire during a doubleheader between the Miami Marlins and the Atlanta Braves at Truist Park in Atlanta. She worked first base in the first game and was behind home plate calling balls and strikes in the second game on August 10, marking the first time a woman has served as home plate umpire in an MLB regular-season game. Pawol, a veteran minor league umpire, received widespread recognition and praise for breaking MLB's nearly 150-year gender barrier in officiating. Her debut came under intense scrutiny, including some criticism of her first called pitch behind the plate, but she was generally regarded as having performed well. Pawol expressed that umpiring is in her DNA and described the experience as a dream come true. Her game-worn hat is set to be enshrined in the Baseball Hall of Fame, underscoring the historic significance of her achievement.
