Question

Do teams in college baseball play 3 game series against each other or only 1 game against each other?

Answer 1

They play 3-game series.  

Answer 2

It depends.

Usually conference opponenets will play a two day, three game series over a weekend but a non conference opponent will be a midweek doubleheader (2 - 7 inning games) or a single 9 inning contest.  Travel occasionally plays a factor but usually its a conference thing.
