Derrick May, a longtime member of the Cardinals’ organization who has mostly worked with hitters in the minor leagues, will be leaving the organization as part of the moves expected to be made with Mike Matheny’s coaching staff.

May served the Cardinals in the major leagues this past season as the assistant hitting coach.

General manager John Mozeliak confirmed May’s departure from the club Monday, though he said other decisions had not been finalized. Mozeliak said there will probably be other changes to Matheny’s staff.

The entire staff may not be completed until later this week, at the earliest. May’s departure and Jose Oquendo’s decision to remain in Florida as an instructor for the Cardinals’ minor-league players leave at least two roles vacant.

When Oquendo took a medical leave for the 2016 season, it prompted some reshuffling of roles in March, and the Cardinals have said they wanted to reconsider the staff and responsibilities given the time they’ve had to evaluate the past season.
