100 Facts for the 2021 Fantasy Baseball Season

No opinions. No fluff. Just facts.

As the old saying goes, imitation is the sincerest form of flattery. Each summer, one of the trailblazers of the fantasy sports industry, ESPN’s Matthew Berry (@MatthewBerryTMR)—and star of the Marvel Cinematic Universe in Avengers: Endgame—writes his “100 Facts for the Fantasy Football Season” article for the upcoming NFL season. It’s always one of my favorite reads for fantasy football prep season. Simple, concise, and informative.

So as a way of paying homage to one of the titans of the fantasy sports industry, I thought I would compile a list of some of my favorite stats that I’ve come across during fantasy baseball draft prep season. Since Berry has turned his focus solely towards fantasy football over the past decade, I thought I would give baseball a shot. I salute you, Talented Mr. Roto.

So, without further ado, my 100 facts for the 2021 fantasy baseball season:

    This was clever and fun

  2. Floyd says:

    It was fun – nice work! I am going to say that Hampson being the everyday CF for the Rockies is not a fact though.

    • Lucas Spence says:

      Thanks for reading Floyd. Yeah, still an unsettled situation for sure in the Rockies outfield. The Rodgers injury certainly clears the way for regular playing time for Hampson in the early part of the season. Feels like a make-or-break season for him for sure.
