Last night, Ken Griffey Jr. hit the 564th home run of his career to move into 10th place on the all-time list. Reading about his accomplishment, I was surprised he was so far up on the list, given the number of injuries he’s had since coming into the league in 1989. That got me wondering about what might have been had Griffey stayed healthy throughout his career…if he would have lived up to the promise of his youth when he was predicted to become one of the game’s all-time greats.
Looking at his stats, I assumed a full season to be 155 games and extrapolated what his home run total would have been for each season after his rookie year in which he played under 155 games. Given that methodology, Griffey would have hit about 687 home runs up to this point. In two of those seasons, 1995 and 2002, his adjusted home run numbers were far below the usual because of injuries limiting his at-bats and effectiveness at the plate. Further adjusting those numbers brings the total up to 717 home runs, good for 3rd place on the all-time list and a race to the top with Barry Bonds.
Of course, if you’re going to play what-if, Babe Ruth had a couple of seasons in which he missed a lot of games and also played in the era of the 154-game season. Willie Mays played a big chunk of his career in the 154-game season era as well. Ted Williams, while known more for hitting for average, missed a lot of games for WWII & the Korean War (almost 5 full seasons) and played in the 154-game season era…and still hit 521 home runs.
