See the link below to the page showing the updated single season BLB records, through the completion of last season:

These include pre-online stats for most categories except batting average allowed and HR/9 (we didn’t track this on the previous leaderboard for some reason and it’d be too much work for me to go back and check now).

In reviewing the league leaders for this season I don’t see any of these changing after the completion of this year.
