Ken Griffey Jr., Rickey Henderson will once again stand in a batter's box during Japan Opener

It's hard to believe, but Major League Baseball's Opening Day is just EIGHT days away. The Mariners and A's will square off at the Tokyo Dome for a two-game series from March 20-21. Left-hander Marco Gonzales will open things up for the Mariners, while Mike Fiers handles the honors for Oakland.

But, much more importantly, on Tuesday, we learned who will be part of the first pitch ceremonies. Along with Japanese legends Masanori Murakami and Kenji Johjima, the world will once again see franchise legends Ken Griffey Jr. and Rickey Henderson standing in a batter's box.

It is typical for a person (or thing) to stand as a hitter during first pitches in Japan, but will Griffey take it to another level and bring a bat? Will he swing that beautiful swing?

Will Rickey draw a 14-pitch walk, or hit a homer of his own? Will he trot around the bases like he's dancing at his best friend's wedding?

We'll all just have to tune in and see.
