Wendy Selig-Prieb was the president and chair of the board of the Brewers when she was promoted to chief operating officer.

Wronski is the only female COO for a major league franchise.

There are two women working as president of business operations for MLB teams, one of which is Catie Griggs with the SeattleMariners. The first U.S. major sports franchise to have women as president and general manager has a new leader. Kim Ng was hired as general manager of the Miami Marlins.

Wronski has 20 years with the Brewers. She is the new president of business operations, a position that hasn't been filled in a long time.

"I'm grateful for the tremendous opportunities the Brewers have provided me throughout my career and aim to continue in my efforts to champion aspiring women in the sports industry," Wronski said in a statement.

Wronski was the general counsel and senior vice president of administration.

She will be in charge of the strategy and business analytic teams.

Wronski was a law school faculty member.

The Brewers have a new executive vice president-chief commercial officer. Consumer marketing will be overseen by Hart Lund. He was above ticket sales, suites, concerts, and business developments.
