The Miami Marlins became the first professional U.S. sports team of one of the four major leagues to have women serving simultaneously as president and general manager.

The Marlins named Caroline O’Connor their president of business operations. Kim Ng was named general manager in November 2020. O’Connor will handle the off-field business while Ng continues to run the team on the field.

"I've always worked for first-class organizations, and that's certainly what [chairman and principal owner] Bruce [Sherman] wants to see here and really what the mandate is," O’Connor said in a news conference on Monday, via the team’s website. "I think using best practices and being the kind of organization that people want to work for and want to support the community, that's exactly what we want here, and a lot of where I came from."
