It appears as if when you display the active roster "after" it expands to 40 - and you use the pitcher stats view, some batters appear as SPs in the list. If you open the players record, however, his true position and stats are shown. I just noticed this so haven't had a chance to test the conditions exactly, but it's def not quite right.
I just finished my 3rd season with a 16 team fictional league, placed 2nd, 2nd, and then 1st all season long until the last game of the season then dropped to 2nd (again) ugh. But I'm loving it
PS: A nice future addition would be to have a managers win-loss history somewhere
