About Ken Griffey Jr.
Ken Griffey Jr. — "The Kid" — is one of the most iconic and beloved players in baseball history. He spent the first and most celebrated chapter of his career with the Seattle Mariners (1989–1999), where he became the face of the franchise and one of the most electrifying players the game has ever seen. He then played for the Cincinnati Reds (2000–2008) before returning to the Seattle Mariners (2009–2010) to finish his career. Griffey retired with 630 career home runs (7th all-time), 13 All-Star selections, 10 Gold Glove Awards, the 1997 AL MVP Award, and four consecutive AL home run titles (1996–1999). He was inducted into the Baseball Hall of Fame in 2016 on the first ballot with 99.3% of the vote — one of the highest percentages in history. His combination of elite power, defense, and pure joy for the game made him a generational talent who transcended the sport.
