The 2019 Seattle Mariners Information Guide is a great resource for information on players (Major League & Minor League), historical information and statistics, as well as bios on Hall of Famers Ken Griffey Jr., Edgar Martinez and Dave Niehaus.
This year’s media guide features Edgar on the cover, celebrating his upcoming induction into the National Baseball Hall of Fame this summer in Cooperstown, NY. Martinez becomes the 2nd Mariner to be elected to the Hall of Fame — joining Griffey, who was inducted in 2016. In his 10th, and final, year on the BBWAA ballot, Martinez received 85.
