Roster Rules Series

As we enter the free agency period, you're likely to hear a lot of terms about transactions that you may or may not be very familiar with. Over the coming posts, I am going to go over a lot of the concepts involved with major and minor league transactions, and the impact that they can have. Some of them are pretty straightforward, and some are confusing. I am hoping to shed some light on those ones.

2. The 40 man roster
3. The Disabled List
4. Free Agency and Free Agent Compensation
