The only other members in this exclusive club are Jay Buhner, Edgar Martinez and Dan Wilson, The (Tacoma, Wash.) News-Tribune reported.
Griffey will be inducted Saturday ahead of the Mariners' game against the Milwaukee Brewers at Safeco Field.
“Having this, I understand the honor that it brings,” he said Friday at a luncheon in honor of his induction. “It’s a lot easier to be in center field and stand at home plate than it is to talk in front of thousands of people.”
“I was nervous three weeks ago. I was nervous a month ago. I was nervous two months ago when they told me. I grew up in a household where it was a lot easier to talk about somebody else than talk about yourself," he added.
“It’s tough to put into words what this award means,” Griffey said. “The best way I could describe it is that I couldn’t do it without a whole lot of people here. There are a whole lot of people that did wonderful things for me to be here.”
Griffey hit a franchise-record 417 home runs in his 10 seasons with the Mariners and had 630 home runs total in his 22-year Major League career.
