BACK TO SLIDE
Ken Griffey Sr. and Ken Griffey Jr. combined for an astonishing 41 years in Major League Baseball -- spanning five decades, from 1973 through 2010. And for two brief seasons, in 1990 and 1991, the father-son duo became the first, and to this point only, such pair to ever play on the same team.
On this day 25 years ago, the Griffeys made history by suiting up together as members of the Seattle Mariners for the first time. The feat in itself is remarkable, but Senior and Junior made it even more memorable by hitting back-to-back singles in the first inning. Both wound up scoring, putting the Mariners ahead 2-0. They'd go on to win 5-2.
The Griffeys made more history the next month, when they became the first father and son to hit back-to-back home runs in a game against the California Angels.
On the anniversary of the pair's historical day, click through the gallery above to see both Griffey's greatest moments on the baseball field. Be sure to also watch the video below to watch Senior take a playful dig at his son's on-field misfortune.
