Here's the initial version of the Top 300 for 5x5 mixed fantasy baseball leagues. We'll be keeping this updated through Opening Day and beyond, and all of this year's draft guide materials will be presented on NBCSports.

We've been here all through the offseason to help you get ready for your Fantasy baseball draft, with rankings, sleepers, breakouts, and busts, tiers, top prospects, and so much more on CBSSports.com and our Fantasy Baseball Today podcast.

Nothing better mimics the real-life experience of an MLB executive than participating in a fantasy baseball dynasty league. The year-to-year control of a team offers unmatched control of both your roster and your short- and long-term directions.
