I think I understand the issue you are seeing BradWilliamson.
The reports page in the team tabs does seem to have some missing splits for pitching reports.
If we compare the pitching reports vs hitter reports the amount of splits to select from is a little lopsided towards hitters. It doesn't even seem like they are mistakenly in the hitters splits by accident. They should be able to have stats in regards to runners on base, which bases, and the counts the hitter is hitting in.
You can compare the split options a hitter gets...
Versus what pitchers get...
It is also worth noting that just like stated when the hitters attempt to view more advanced splits such as Runners on 2nd base they are indeed blank.
In the end, Matt is correct and you are correct Brad. The splits should be able to apply to hitters but they're not coming back with any stats at the moment. Guessing a bug is causing that not to show. Regardless a pitcher should have similar splits and those are missing so a closer look at the splits in the info>reports section might be in order.
Thanks
