As @native seemed to be questioning, I've noticed a lot of 8 and 9 hole hitters watching the post-season games w double digit HRs this year, when they barely hit more than low single digits their first 2 - 3 seasons.
Juiced balls, juiced players ... neither would surprise me. Although there are many more teams these days w 4th and 5th year seniors.
Once the COVID players are done (this year?), I think the comps will be more valid.
