I'm experiencing the problem again. I installed the game in my new laptop (old one died) and baseball quality was correct. The only mod I used was Questdog's names mod. It is possible that could be my issue. I will check in with him.
EDIT:
Questdog's thread confirms the baseball quality issue in post 15 and 16. Thanks everyone for your help.
