Mariners manager Mike Hargrove is resigning as of the end of Sunday's game against the Toronto Blue Jays. The Mariners said John McLaren will be the new team manager and start the job Monday when Seattle plays in Kansas City. Hargrove has been manager of the Mariners since October 2004. He is fifth among active managers with 1,187 career wins, including 191 with Seattle, heading into Sunday's game. Hargrove said he has realized over the past few weeks that he cannot continue to do the job if his passion has begun to fade. He said this has been a great place to work and he's proud of the work the team has done to turn the club around over the past three years. Hargrove said he has high expectations for the team this season.
