Playoff fantasy baseball leagues for the 2026 MLB postseason

FanRanked hosts free playoff fantasy baseball leagues that start the week the bracket is set. Three formats, one for every kind of group: a real draft for the twelve playoff teams, a no-draft box pool with an optional MLB playoff bracket challenge, and a daily One and Done game where each player can be used once all October. Every game is scored from the official MLB box score overnight. Joining is free with a Google or email account; hosting needs FanRanked Pro.

Key dates for the 2026 MLB postseason

Three playoff fantasy baseball formats

Pick the one that fits your group. A twelve-person league that wants a draft night takes Playoff Draft. An office or a group chat of any size takes the October Box Pool. A group that wants a decision every day takes One and Done. All three use the same nightly scoring and the same round multipliers.

One and DoneNo draftNoneOne hitter and one pitcher, each used once all OctoberNo2 to 200 entries

Playoff Draft is the closest thing to a normal fantasy league: a snake draft, live or slow, from every hitter and pitcher on the playoff rosters, ranked by the FanRanked season board. The commissioner picks points or rotisserie. There are no lineups, waivers or trades, so what you draft is your team. Playoff Draft rules.

October Box Pool is the format for a crowd. Before the Wild Card round, everyone picks one player from each box of similar players (aces, closers, sluggers), with at most three players from any one MLB team. Points multiply by round, eliminated players stop scoring, and after the Division Series you may swap two of them out. Turn on the bracket and every entry also picks the winner of every series. October Box Pool rules.

One and Done is the daily game. Every game day you pick one hitter and one pitcher who play that day; once a pick locks at first pitch, that player is used up for the rest of October. Spend the stars in the Wild Card round or save them for a 2x World Series? A public One and Done pool runs every postseason and anyone can join it free. One and Done rules.

Long Ball is the spring format: draft hitters and score one point per foot of Statcast home run distance all season. It also runs as a postseason league for groups that want a bomb-only October. Long Ball rules.

How playoff fantasy baseball scoring works

Points formats score every box-score event. The default formula gives hitters 1 for a single, 2 for a double, 3 for a triple, 4 for a home run, 1 for a run, 1 for an RBI, 1 for a walk or hit by pitch, 2 for a stolen base and minus 0.5 for a strikeout. Pitchers get 1 per inning, 1 per strikeout, 4 for a win, 3 for a quality start, 5 for a save, 3 for a hold, minus 2 for an earned run or a loss, and minus 0.5 for each walk or hit allowed. Relievers score, so closers on deep teams are real assets.

Every point is then multiplied by the round: Wild Card 1x, Division Series 1x, League Championship Series 1.5x, World Series 2x. A home run in the World Series is worth twice a home run in the Wild Card round. Playoff Draft leagues can run rotisserie categories instead (runs, home runs, RBI, stolen bases, average, wins, saves, strikeouts, ERA, WHIP), with no multipliers. Commissioners can change every weight and multiplier before the league opens, and the Rules tab inside the league always shows the numbers in force.

Only postseason games count. Regular-season stats never score, even from the final weekend. When a team is eliminated its players keep the points they banked and score nothing more, and the standings update as soon as the box scores are final, usually within an hour of the last out.

How to win a playoff fantasy baseball league

MLB playoff bracket challenge

The bracket is built into the October Box Pool as an optional side game. Before the first Wild Card game every entry picks the winner of each series, all the way to the champion. Correct picks earn 1 point in the Wild Card round, 2 in the Division Series, 4 in each League Championship Series and 8 for the World Series, on a separate leaderboard next to the player standings. Bracket rules.

Host one for your friends, your office, or your dynasty league

Create the league, keep or change the default scoring, and send one invite link or the QR sheet. Members join free with a Google or email account and there is nothing to install; the league runs in the browser on a phone or a desktop. Commissioners get a note on every tab, league chat, an activity feed, a roster editor, co-commissioners and share cards. Dynasty leagues use these formats to keep the group together through October, since the same twelve people can play a Playoff Draft in the two days after the field is set. Hosting needs FanRanked Pro, playing is always free, and FanRanked never handles entry fees or pool money.

Questions

How does a playoff fantasy baseball league work?

Only postseason games count. You draft or pick players from the twelve MLB playoff teams, points multiply as the rounds go on (Wild Card to World Series), and a player stops scoring when his team is eliminated. FanRanked scores every game from the official MLB box score overnight.

When do playoff fantasy baseball leagues start in 2026?

The 2026 regular season ends Sunday, September 27 and the Wild Card round opens Tuesday, September 29. FanRanked sets the twelve-team field the moment it is clinched. Playoff Draft leagues draft in the two days between; October Box Pool and One and Done entries lock at first pitch of the first Wild Card game, so you can join right up to that moment.

Is there a free MLB playoff bracket challenge?

Yes. The October Box Pool includes an optional bracket: pick the winner of every series before the Wild Card round and earn bracket points by round (1 for a Wild Card series, 2 for a Division Series, 4 for a League Championship Series, 8 for the World Series) on a separate leaderboard next to your player picks. Entry is free; there are no fees and no pool money.

Can I join a playoff fantasy baseball league without a draft?

Yes. One and Done and the October Box Pool have no draft: you pick one hitter and one pitcher per day, or one player per box, and lock them before first pitch. Playoff Draft is the format with a live or slow snake draft in the browser.

How is a playoff fantasy baseball league scored?

Points leagues use a box-score formula (default: single 1, double 2, triple 3, home run 4, run 1, RBI 1, walk 1, stolen base 2, strikeout -0.5 for hitters; inning 1, strikeout 1, win 4, quality start 3, save 5, hold 3, earned run -2 for pitchers) and multiply by round: Wild Card 1x, Division Series 1x, League Championship Series 1.5x, World Series 2x. Playoff Draft can run rotisserie categories instead. Commissioners can change every number before the league opens.

What happens when my player's team is eliminated?

He keeps every point he already scored and scores nothing more. In the October Box Pool you may swap up to two eliminated players after the Division Series for unused players from the same box on surviving teams. In Playoff Draft and One and Done there are no replacements, so picking teams that go deep is half the game.

How many people can play in one league?

One and Done pools run from two to two hundred entries. October Box Pools have no size limit. Playoff Draft leagues run four to twelve teams so every roster has enough playoff players to draft from.

How do I start a playoff fantasy baseball league for my friends or office?

Pick a format, keep or change the default scoring, and send one invite link or the QR sheet. Everyone joins free with a Google or email account; there is nothing to install. Hosting needs FanRanked Pro, playing is always free, and FanRanked never handles entry fees or pool money.
