FWIW, the correct league level stats seem to show up in the table. However, sometimes the level does not appear next to the player’s name in the “Name” field. Of course I don’t have an example to give at the moment…
Jared Young’s stats are a combination of AAA and A from this year, but his player’s name in the stat tables do not indicate a current minor league level. At a glance, it appears he is on the Mets major league club.
What’s happening here is that for some minor league players who have been in the majors, very occasionally the site has decided they are major leaguers. The reason for this is pretty tricky and I will need to spend some time on it. Appreciate the bug report!
