MIAMI — Kim Ng started her Major League Baseball career as an intern, and three decades later she’s still on the rise and shattering ceilings.

Ng became the majors’ highest-ranking woman and Asian American in baseball operations when she was hired Friday as general manager of the Miami Marlins. She is believed to be the first female GM in a major professional sport in North America.

Ng (pronounced Ang) won three World Series rings while spending 21 years in the front offices of the Chicago White Sox (1990-96), New York Yankees (1998-2001) and Los Angeles Dodgers (2002-11).
