The Miami Marlins made history on Monday, hiring Kim Ng as their general manager.
Ng becomes the first woman and Asian American to serve as the general manager of a Major League Baseball club.
The Chicago White Sox congratulated Ng on her achievement.
"Congratulations to Kim Ng on making history," the White Sox wrote on Twitter.
"We're proud that the White Sox were one step on your baseball journey."
Former White Sox manager and player Ozzie Guillén also congratulated Ng on Twitter.
Ng went to the University of Chicago and her baseball journey began with an internship with the White Sox. She was eventually hired full-time in 1991, rising to the rank of Assistant Direct of Baseball Operations while Ron Schueler was the general manager in 1995.
“When Kim Ng walked through our ballpark’s doors to begin her Major League Baseball career, she quickly impressed us all with her knowledge, drive and hard work," White Sox Senior Executive Vice President Howard Pizer said in a statement.
"We are very proud to be one of the fortunate organizations to have worked with Kim on her journey into a role she truly deserves and earned. Baseball is stronger when people of all backgrounds, experiences and identities are involved. Kim most certainly is proof of that, and her friends at the White Sox celebrate her accomplishment.
"On behalf of the entire White Sox family, congratulations to Kim on becoming Major League Baseball’s first female general manager. We are so proud of her start with us and congratulate her on this historic first."
Ng left the White Sox to work in the American League offices in 1997 before joining the New York Yankees as the Assistant General Manager to Brian Cashman.
