Ken Griffey Jr.

Griffey's second season, 1990, was just as thrilling. The highlight of the season, however, occurred in August when his father, recently released by the Cincinnati Reds, joined the Mariners. On August 31, 1990, they became the first father-son duo to play on a major league team together. The Griffeys comprised twothirds of the Mariner outfield, with Junior Griffey playing center and Griffey Sr. playing left. They also followed each other in the lineup. On September 14, 1990, the duo hit back-to-back homers. It's a record that will likely never be broken.

For father and son, the chance to play together was the dream of a lifetime. Griffey's words in the St. Louis Post-Dispatch speak about the experience. "I got to play with my dad. I got to go to work with him. That's the biggest thing that ever happened to me other than the days my kids were born. That's bigger than any record I'll ever set.… To play alongside him was the best."
