Lew Wolff, the longtime managing partner of the A’s ownership group, is stepping away from that role and selling most of his stake in the club to the team’s other owners, The Chronicle has learned.

The move is expected to be announced later today. John Fisher, who is the majority partner, will take over as managing partner.

In addition, Michael Crowley will move from team president to a senior advisor to the ownership group. The new A’s team president will be Dave Kaval, who is currently president of the San Jose Earthquakes. Crowley has been the A’s president for the past 19 years.

Wolff, who served as managing partner for 11 years, will become the A’s chairman emeritus.

The Chronicle reported on Oct. 31 that one or more of the A’s owners might sell stakes in the club because of the looming possibility that the team will no longer receive revenue-sharing money in the new collective bargaining agreement with the Players Association.
