Overview of Yahoo Fantasy Baseball Pro Leagues

If you've ever played in a free Yahoo Fantasy Baseball league, you already know how to play and most of the rules for Pro Leagues -- they're virtually the same game, except for the pricing… and the payouts!

Play Ball! Take the field and sign up for a Fantasy Baseball Pro League.


Yahoo Fantasy Baseball Pro Leagues is a skill competition against others to win cash prizes using your knowledge and skill in assembling and managing a fantasy baseball team made up of real-life Major League Baseball (MLB) players.

The better your players perform in real-life games, the more value they bring to your fantasy team.

You can sign up for as many Fantasy Baseball Pro Leagues as you want -- there's no limit!

After reading this overview, don't forget to read the Official Rules and Additional Terms of Service for Pro Leagues (they govern your participation and eligibility in the game).

If there's a conflict between the Official Rules, Additional Terms of Service, and/or these instructions, the Official Rules always have the final say.

Playing Season

Yahoo Sports Fantasy Baseball Pro Leagues are offered in two different scoring types: Rotisserie and Head-to-Head.

While the exact length and format of a league's playing season depends on its scoring type, all leagues follow the MLB regular season schedule and begin play on Opening Day.

Regardless of a league's scoring format, the MLB playoffs have no bearing on the game -- All action and scoring takes place during the MLB regular season.

If your League conducts its draft after a Game Week is already underway, your Team/League will not begin its season until the start of the following Game Week. Your League's Fantasy Regular Season will also be shortened accordingly.

Head-to-Head playing season

The playing season for all Head-to-Head scoring leagues is broken out into 25 "Game Weeks." Each week, you're matched up against another team in your league to see who comes out on top.

Game Weeks generally follow a Monday-Sunday (7 day) schedule, beginning each Monday morning at midnight PT and ending the following Sunday night at 11:59:59 PM PT, or at the conclusion of the last regularly scheduled game for that Sunday (whichever comes first).

Game Weeks 1-22 constitute the "Fantasy Regular Season," and Game Weeks 23-25 make up the "Fantasy Playoffs."

At the conclusion of Game Week 22, the top teams in the league's standings square off against each other to decide the champion in the league's playoffs, taking place in Game Weeks 23-25.

Rotisserie playing season

Rotisserie Scoring Leagues will always follow the default Game Week 1 schedule, regardless of the date that each League conducts its draft.

In Leagues that use Rotisserie Scoring, your Team/League will always begin its season on the next day following your draft.

In Rotisserie scoring leagues, all scoring is cumulative over the course of the season (there are no "Head-to-Head" matchups, "Game Weeks," or league playoffs) and the league champion is determined at the conclusion of Game Week 25.

Game week exceptions

  • Game Week 1 includes Opening Day 
  • Game Week 15 runs for the 2 weeks surrounding the All-Star break

Format and Scoring

Pro Leagues are open to anyone and everyone, and every league contains exactly 12 teams.

All leagues use the same standard settings regardless of their scoring format, and are offered in 5 different competition levels:

  • PRO20 ($20 entry fee)
  • PRO50 ($50 entry fee)
  • PRO100 ($100 entry fee)
  • PRO250 ($250 entry fee)
  • PRO500 ($500 entry fee)

Once you're signed up, you'll be randomly placed in a league with other managers who have chosen the same competition level, scoring system, and draft date and time.

Throughout the season, the players on your team earn fantasy points for their performances in a variety of real-life statistical categories.

In a Head-to-Head league, your goal is to score more points with your players each week than your opponent's team.

In a Rotisserie league, your goal is to accumulate the most points (using several different statistical categories) over the entire playing season.

For more details, see our Head-to-Head and Rotisserie scoring overview articles.


All Pro Leagues conduct live, online drafts in either a standard or auction format. When you sign up, you'll get to pick the date and time that works best for you.

If all 12 slots in your league are full by your scheduled draft time, your league will conduct its draft to determine the rosters for each team.

If there are any empty slots, your league will be disbanded and everyone will be issued a credit for use towards a team in another Pro League (you'll automatically be issued a refund if you don't use your credit before registration closes).

Drafting during a Game Week

Head-to-Head leagues - If a Game Week is already underway when your league drafts, your league won't begin until the start of the following Game Week and its Fantasy Regular Season will be shortened accordingly.

Rotisserie - In rotisserie leagues, your league will begin play the day following your draft if a Game Week is already underway when your draft takes place.

For more information, see the dates and deadlines for the current season.

Manage Your Roster

Once your draft is complete, you'll have a roster of starting and bench players. If don't make any changes, your starting line-up will consist of the starters that you designated during the draft.

Throughout the season, it's up to you to make adjustments to your roster based on your knowledge and skill in evaluating how your players are performing.

You can manage the players on your team by moving them between starting and bench positions, adding or dropping them through waivers or free agency, or by trading them with other teams.

Keep in mind, there are deadlines for when roster moves can take place.


Real-life MLB teams use "waivers" to make a player's rights available in a way that gives every other team a fair chance to claim them.

Just like in the pros, Pro Leagues feature a waiver system that builds upon the real-life waiver concept in a number of ways.

Learn more about our waiver system using our waivers overview.

Free Agents

All players not currently on a team in your league (and who are not currently on waivers) are considered free agents.

Free agents may be acquired by any manager in the league on a first-come, first-served basis.

Learn more about the free agency system using our free agency overview.


A trade consists of two teams exchanging players with each other. Learn how to conduct trades (and how they're reviewed for fairness) in our trading overview.

Trades can be executed anytime after your league drafts up until your league's trade deadline.

Playoffs and Winning

The playoff system in Pro Leagues is different depending on your league's scoring format.

Head-to-Head Scoring Leagues

At the conclusion of Game Week 22, the top 6 teams in the standings are matched up against each other in a 3-week playoff for bragging rights and cash payouts!

Get a full rundown of the playoff system by reviewing how playoff match-ups are determined and the head-to-head tiebreaker rules.

Rotisserie Scoring Leagues
