On August 31, 1990, Ken Griffey Sr. and Ken Griffey Jr. made major league history as the first father and son to play together in an MLB game.
Ken Sr. had joined the Mariners just weeks earlier, reuniting with his son, who was already emerging as one of baseball’s brightest young stars.
Batting second and third, respectively, the Griffeys each singled in the first inning. Like father, like son.
They would go on to play 48 games together across the 1990 and 1991 seasons before Ken Sr. retired.
The Griffeys remain one of just two father-son duos to play together as MLB teammates. Tim Raines Sr. and Tim Raines Jr. did it once with the Orioles in 2001.
Some family businesses are just a little more historic. ⚾️
