Been a while, however the NCAC used to play DH's on both Saturday and Sunday. It was two seven inning games. If your Saturday starter could not go 7, you were often in trouble. Then they changed to a 9 inning then a 7. They did this because some of the schools in the conference did not want players missing classes. In fact schools like Kenyon used to play all there out of conference games during a 2 week spring break. Then when confernce baseball started they only played on the weekends.
This has all changed there is still at least one DH a week, however they are playing some weekday games as well.
