The Miami Marlins named Caroline O’Connor as president of business operations. They are now the first U.S. major sports franchise with women holding the roles of president and general manager.

O’Connor joined the Marlins in 2017 as senior vice president and chief of staff. She was promoted in 2019 to serve as chief operating officer under owner Bruce Sherman.

The Marlins also made history in 2020, when they made Kim Ng the first female general manager in MLB history. Ng and O’Connor each will oversee the team’s day-to-day operations. Ng will continue to handle personnel decisions, while O’Connor will oversee sales, partnerships, human resources, equity and inclusion, finance, legal, communications and more.

The Marlins announced in September that they mutually agreed to part ways with longtime manager Don Mattingly.
