The Cardinals announced Thursday that manager Mike Matheny has signed a three-year extension running through the 2020 season, and also announced two promotions to the major-league coaching coaching staff.

Memphis manager Mike Shildt has been promoted to a new position as quality control coach and Palm Beach manager Oliver Marmol will become the team’s first-base coach. Bill Mueller will return to his previous job as assistant hitting coach, replacing Derrick May, who has left the organization.

All of the team’s other coaches will return for next year in the same positions, the Cardinals said in a press release.

Matheny has led the Cardinals to a 461-349 record over his five seasons as manager, averaging 92 wins per season, the most wins among all managers since 2012. The Cardinals won three consecutive National League Central Division titles (2013-15), a National League Championship in 2013 and made the postseason in four of Matheny’s first five seasons. Matheny’s .569 winning percentage currently ranks 18th all-time in the history of Major League Baseball managers and he stands 5th on the Cardinals all-time managerial wins list.

“Mike has continued the Cardinals tradition of winning in his first five years as manager and we are happy to extend his contract leading our club on the field through 2020,” said Cardinals Principal Owner and CEO, Bill DeWitt, Jr.

The Cardinals also announced that Bob Gebhard is returning to the organization as a Senior Special Assistant to the General Manager. Gebhard was a past member of the Cardinals front office staff from 2000-04 and will be entering his 53rd season working in professional baseball.
