Here are some final-month rankings. I’m a little short on comments, since I’ll be hopping on a plane awfully early Monday morning. Please try not to get too bent out of shape if your star player isn’t listed where you like ... anything can happen in a month.
As always, players are ranked by position and then combined into an overall top 300 list.

- I’ll probably get some complaints about Ha-Seong Kim being too low, and I have moved him up because he’s become a leadoff man and he’s been a whole lot more aggressive on the basepaths than in his first two season in MLB. However, the offensive improvement seems to be largely a fluke. His 28.5% hard-hit rate is actually down from his first two seasons, and it’s pretty remarkable that he has 17 homers with just 17 barrels. The typical player has 58% as many homers as barrels this season.
