Mariners Relieve Jack Zduriencik of G.M. Duties

Seattle Mariners President and Chief Operating Officer Kevin Mather announced this morning that EVP of Baseball Operations & General Manager Jack Zduriencik has been relieved of his duties, effective immediately.

Jeff Kingston, who has been the Mariners Assistant General Manager since 2009, will handle the GM responsibilities for the remainder of the 2015 regular season.

Mather said, “We have reached the point when change of leadership of our baseball operations is needed for the Seattle Mariners to reach our goal of winning championships. We are very disappointed with the results this season, and are not satisfied with the current operation.
