Big League Impact began as a charity fantasy football league in 2013. While our organization has grown exponentially since then, each fall, we are thrilled to return to our roots and host a number of fantasy football leagues where pro athletes and their fans can go head to head while raising money for a variety of causes and charities picked by participating MLB players. Details about our league format, lineups, scoring, playoff rules and prizes are available below.

Our 2025 fantasy league kicks off Friday, Sept. 5, with a one-of-a-kind gameday experience at Busch Stadium — click here for more information and to register.

The season offers a weekly head-to-head matchup featuring a weekly salary cap format. Leagues are powered by RT Sports; please visit their FAQ page for any questions not answered here.

Choosing Your Lineup
A salary cap format (DFS) means that each week, your team receives a budget of $50,000 virtual “dollars” to “spend” on drafting your team. This format lets you pick a new team every week, unlike season-long rules where once a player is drafted, he’s no longer available.

Team owners will assemble their 9-player lineup for the week while remaining below the salary cap. Owners are free to swap players in and out of their lineup at any time up until the player’s game kicks off. The salaries of each player will be updated each week to reflect matchups, injuries and performance trends. The higher the projected points a player is expected to produce, the more you’ll have to spend to add them to your lineup. You’ll have to budget wisely if you want someone like Patrick Mahomes or Christian McCaffrey on your roster. Each week, rosters reset and you can pick a new team! No need to worry about injuries, leaving a player on the bench or waiver claims.

Weeks 1-14
The regular season for all leagues will last 14 weeks. Weeks 1, 2 and 3 of the season will be “all-play” weeks, meaning the top scoring six teams in each league will receive a win and the bottom-scoring six teams in each league will receive a loss. After that, from Weeks 4 through 14, each team will play the other teams in their league once.

Playoffs
After Week 14, six teams will make the playoffs: the four teams with the best records, plus the two teams with the highest cumulative point total among the remaining eight teams (who will enter as the #5 and #6 seed wild card teams).

Playoffs will be a head-to-head bracket format that takes place over weeks 15, 16 and 17.

After Week 14, six teams will make the playoffs. The top four teams are based on wins and losses with tiebreakers applied; there are two wildcard teams for the remaining eight teams, determined by most points scored in the regular season.

Playoffs will be seeded by wins and losses. In Week 15, the #1 and #2 seeds will receive a bye. Seeds #3 and #6 will play head-to-head, as will seeds #4 and #5. Winners from Week 15 will advance to play the top two seeds in Week 16.

Tiebreaker
If two or more teams in a league have the same win-loss record, the tie will be broken using the following criteria, in order:

  • Division Win-Loss Record
  • Total Points Scored in all games played.
  • Head-to-Head Win-Loss Record against all tied teams
  • Total Points Scored in Head-to-Head games against all tied teams

Wildcard Teams
The two wildcard teams will be the teams with the most total points scored in all games that are not one of the top four seeds. In the event that two or more teams, that are not the top four seeds, are tied for the most total points scored in all games the tie will be broken using the following criteria, in order:

  • Overall Win-Loss Record
  • Division Win-Loss Record
  • Head-to-Head Win-Loss record against all tied teams
  • Total Points Scored in Head-to-Head games against all tied teams
