Ken Griffey Jr. dons backward cap during Hall of Fame speech

In traditional Ken Griffey Jr. fashion, the MLB icon donned a backward hat at the end of his Hall of Fame induction speech in Cooperstown, N.Y., on Sunday.

USA Today considers Griffey’s backward hat as baseball’s last pop culture icon and that he was the last player that non-baseball fans could recognize.

The slugger finished his career with 630 home runs, sixth on the all-time list, and 1,836 RBI, 15th all-time. He made it to 13 All-Star games, won 10 Gold Glove awards and seven Silver Slugger awards. Griffey was the 1997 American League MVP after smashing 56 home runs and 147 RBI for the Seattle Mariners.

According to The News Tribune, his affinity with backward hats began at a young age.

Ken Griffey Sr. on Thursday said the backward hat started when his son was either 5 or 7. Griffey Sr. had an afro when he played for the Cincinnati Reds and a much bigger head than his son. But Griffey Jr. would want to wear his father’s hat when they would play catch.

So, as the story goes, Griffey Jr. would turn it around to keep the bill of the cap from falling down his face.
