Law: Under-25 October impact rankings

I typically update my ranking of the top MLB players under age 25 once a year, but with this year's playoff rosters loaded with young talent, I've produced this special, shorter edition highlighting the top 10 players on these 10 clubs whose seasonal ages in 2017 were 24 or younger. Fourteen of the 25 players on my list from earlier this season are on playoff teams, and that doesn't include rookies who weren't eligible for the list last time but are now.

Also, there's no Aaron Judge here, as this was his age-25 season. This list is for players who are 25 or younger after July 1.
