    New year, new you, so why not a new game to play, amirite? It can’t possibly be that difficult to build a baseball team and compete against eleven other managers and win a title, can it? I mean, there has to be only one way to play, right? The rules I am sure are simple. It’s baseball. See ball, hit ball, catch ball, throw ball.

    So how hard can fantasy baseball really be?

    Fantasy baseball is an extremely difficult game to play and even harder to master and win. From choosing your scoring type to league type, which categories will you count to how many teams in the league and whether you will re-draft yearly or keep the same teams year over year, starting out can be very overwhelming.

    Luckily, you have me, your fantasy baseball Sherpa. I have played every form of fantasy baseball since I started playing way back in 1998, so I’ve decided to put together a nice, easy to read, but very informative, beginner’s guide to fantasy baseball. We’ll cover all of the different league types, scoring types, most used categories, websites to play on, draft types and touch on a few of the best sites for statistical research and knowledge.

    How Many Teams Should Your League Have?

    First and foremost, there is no true standard number of teams in all leagues. I’ve played in leagues with as few as six teams (though, this was when we added stats up by hand, using newspapers daily) and leagues as deep as 30 teams, where we used real-life salaries and played out 162 game seasons on the CBS platform.

    Before you decide how many teams you want in your league, you need to determine if you will be playing with friends, family and colleagues or with strangers. If it is with the people in your life that you know love and enjoy the game of baseball as much as you do, keep it as small, simple and intimate as possible, especially if you are all learning how to play the game together. An eight or ten team league of new players is a great way to learn and make mistakes together.

    If you are playing with strangers, though, odds are you will play in leagues of 12 to 15 teams. Leagues with more than 15 teams can get very unwieldy and very ridiculous, very quickly. Most sites host 12 team leagues as the standard, though more and more are using 15 teams as the standard bearer for their rotisserie leagues.

    Where to Play Fantasy Baseball?

    ESPN – the original fantasy baseball online platform and the oldest still active platform. Basic, easy to use, great for beginners, but limited customization and not great for anything other than standard leagues.

    Yahoo – probably the best mobile platform, as their app is easy to use and navigate and is updated regularly and rarely has problems. The second oldest running fantasy baseball platform and the place I have been playing for the longest. Like ESPN, it is basic and easy to use, great for beginners, but lacks a depth of customization and really is best just for standard leagues.

    CBS – they were the first place to invest in the diversity of depth that fantasy baseball leagues can have. Great for new players and experienced alike, but has, over the last few years, been rated as the worst place to play fantasy baseball. Everyone’s experience is different though and I know of at least two leagues that have been going strong over on CBS for over 15 years (one is a thirty team league and the other a sixteen team league; both dynasty leagues).

    Fantrax – the Golden Goat, if you will, of fantasy baseball. Fantrax has the most customization of any of the platforms, is constantly updating how to play the game, they are quick to add new players to the league or the minor leagues, they are very active on social media but have a clunky mobile app. Whether you play in their free leagues or cash leagues, the customization available for any and all league types. They are the most in-depth platform around and my absolute favorite place to play.

    National Fantasy Championships (NFC) – these are the big leagues of fantasy baseball. This is where all of the high stakes competitions take place, from the Main Event leagues with an overall prize of $200,000 to the Auction Championships with an overall prize of $30,000, this is not the place for the faint of heart. The stakes and buy-ins are all over the place, with buy-ins as low as only $50 and as high as $15,000, there is something for everyone who is itching to test their mettle against the best of the best.

    What Kind of League Should I Play In?

    Re-Draft League – the most basic and most common league type is the re-draft league. These are leagues where you draft a team, use it for that one season and then that is it. Once the year is over, the team is done. There are probably more re-draft leagues than all other league types combined and nearly all of the high stakes leagues are re-draft leagues. Re-draft leagues are probably the best league types for those new to fantasy baseball, because you only have to worry about one season, the one you are in, and you can make them as user friendly as possible.

    Keeper League – Keeper leagues are like re-draft leagues, except for the fact that you will get to keep X number of your players from your roster from one season into the next. The X number depends on the rules of the league – usually no lower than three players and no more than 10 to 12 players (once you get past keeping half or more of your team, you’re playing in a different league type, in my opinion). Some leagues determine who you can keep based on when they were drafted (like, you cannot keep any players drafted before the fifth round), others just limit you to a certain number of keepers and others determine the cost of the keeper based on specifics such as the round they were drafted in or the auction value they produced.

    Let’s use an example: You are in a 12 team, five man keeper league. That means there are twelve teams and you can keep five players each, that you will have on your roster to begin the next season. So when the next season is here and you are drafting your teams, there will already be 60 players on rosters and no longer in the draft pool. You would then draft to build around your five players. Then do it all again the next year, picking five players again to keep. And continue to do this in perpetuity or until the league closes.

    Dynasty League – the deepest kind of league, dynasty leagues involve you keeping your entire roster season over season. This may or may not include managing a minor league roster or being required to roster X number of minor league players. Every year there are not normal drafts, normally just first year player drafts (a draft involving the most recently drafted MLB players plus international free agents that joined MLB or MiLB over the latest free agency period or IFA period), maybe a free agent draft (if your league doesn’t allow openly adding free agents in the off-season, some leagues will have a free agent draft for teams to draft any league free agents before the season starts that they are interested in) and, occasionally, a minor league draft (for leagues that don’t allow managers to openly add and drop minor league players throughout the season). Leagues can last for decades (I know of a dynasty league that started on the message board the Sons of Sam Horn in the 90’s that is still going strong today) and teams have to craft that perfect strategy of building for the current season but also being competitive year over year without the help of a full draft. More and more players are joining dynasty leagues year over year and I believe this will be the highest played league type very soon.
