Miami Marlins chairman and principal owner Bruce Sherman announced Monday that general manager Kim Ng is leaving after three seasons as general manager. The 54-year-old Ng became the majors’ highest-ranking woman in baseball operations and the first female GM in the four major North American professional sports leagues in a groundbreaking hire in November 2020.

Ng just completed the final guaranteed year in her contract, with the Marlins exercising their team option for her to return for the 2024 season, but Ng declined her mutual option. Sherman said in a statement: “We thank Kim for her contributions during her time with our organization and wish her and her family well. We will immediately begin a thorough and extensive search for new leadership as we plan to continue to invest in the Marlins organization both on and off the field. We are committed to our fans and the South Florida community and look to build off the momentum of the great progress of this year.”

On Monday, Ng told The Athletic about her decision to leave the Marlins: “Last week, Bruce and I discussed his plan to reshape the Baseball Operations department. In our discussions, it became apparent that we were not completely aligned on what that should look like. I felt it best to step away. I wish to express my sincere gratitude and appreciation to the Marlins family and its fans for my time in South Florida. This year was a great step forward for the organization.”

Ng brought in Marlins coach Skip Schumaker ahead of the 2023 season, who went on to lead Miami to an 84-78 record and its first postseason berth since 2020. Before then, the last season in which the Marlins made the playoffs was in 2003, when they won the World Series.
