In the first inning against the California Angels, Ken Griffey Sr. stepped to the plate with one runner on and Kirk McCaskill on the mound. Griffey Sr. promptly blasted a two-run shot to left-center field, laying the foundation for one of the most memorable, yet peculiar moments in Mariners history.
Junior certainly gave new meaning to the phrase, "Like father, like son."
He worked the count to 3-0 before McCaskill served up the pitch he was waiting for. He hit the next pitch to almost the identical spot in left-center field, and created a moment that will live in Mariners fans' minds for years to come.
Griffey Sr. had some words for his son immediately following the back-to-back display, although time has eroded some of Junior's memory of the event.
"The only thing I remember him saying is, 'That's how you do it, son,'" Griffey Jr. recalled.
The moment signified more than just a son following in his father's footsteps. It was a precursor to the many achievements Junior would accomplish in Seattle. Fans were already being exposed to his mystique, something they were counting on to help turn the hope of a promising young baseball team into the reality of a playoff contender.
And although the back-to-back home runs treated Seattle fans to one of the rarest events in the history of Major League Baseball, the home runs said even more to Griffey Sr.
"When [Griffey Sr.] got there, he said, 'This is your team,'" Junior recalled. "'I'm here to have as much fun as I can and enjoy myself.'"
It wasn't long before Junior took his team to new heights. Just one year after hitting those back-to-back shots, he helped the Mariners to their first winning season, finishing 83-79.
Four years after that, they clinched their first division title.
