Kevin Mather

Kevin Mather is an American baseball executive. He is the former president of the Seattle Mariners of Major League Baseball, and is a minority owner of the team.

Mather grew up in Madison, Wisconsin. He graduated from the University of Wisconsin–Madison in 1984, earning a Bachelor of Arts in accounting and risk/insurance. He worked as a Certified Public Accountant at a firm for five years, before joining the front office of the Minnesota Twins, starting as their director of finance in 1989, and receiving a promotion to vice president in 1992.

Mather joined the Seattle Mariners organization in 1996, serving as executive vice president of finance. He was in charge of overseeing the building of Safeco Field. In January 2014, he was selected to succeed Chuck Armstrong as team president.

In July 2018, a Seattle Times article reported that Mather contributed to creating a hostile workplace environment for women. Mather had been the subject of two workplace complaints from female employees in 2009 and 2010. In both instances the employees were compensated an undisclosed sum. The two women eventually left the organization; Mather was retained and promoted.

Mather spoke at a Bellevue Breakfast Rotary Club event in February 2021 in which he confessed to service-time manipulation of players. He made comments about the poor English-language abilities of multiple players of overseas origin on the Mariners. He made specific comments about Japanese and Dominican players, expressing his discontent over their poor English language skills and the need to hire interpreters for them. Mather also commented on the team's profits during the COVID-19 pandemic. The audio was released publicly on February 21, and Mather resigned as president of the Mariners the next day.

Mather and his wife, Shannon, live in Issaquah, Washington. They have three sons: John, David, and Steven.
