One hitter and one pitcher a day. Each player once per season.
Every game day you pick one hitter and one pitcher. Their stats that day score points for you. The catch: each player can be used only once all October, so every pick is also a sacrifice. Spend the stars early or save them for later? The most points after the World Series wins.
One and Done is one of the playoff fantasy baseball leagues FanRanked hosts for the MLB postseason. Entries are free; hosting needs FanRanked Pro.
How it works
Join with the invite link or from the public leagues page. No draft.
Each game day, pick one hitter and one pitcher who play that day. You can pick up to 7 days ahead.
Each pick locks at that player's first pitch. Until then you can change it.
Once a pick locks, that player is used and cannot be picked again.
You may name an alternate for each slot. If your hitter is not in the posted lineup, or your pitcher is not the announced starter, the alternate plays and the original is not used up.
Points are scored from the box score overnight. Standings are the running total.
Scoring
Hitters: single +1, double +2, triple +3, home run +4, run +1, RBI +1, walk +1, hit by pitch +1, stolen base +2, strikeout -0.5.
Pitchers (any pitcher who appears, starters and relievers): inning pitched +1, strikeout +1, win +4, quality start +3, save +5, hold +3, earned run -2, walk allowed -0.5, hit allowed -0.5, loss -2.
Round multipliers: Wild Card 1x, Division Series 1x, League Championship 1.5x, World Series 2x.
These are the default numbers. A commissioner can change any of them before the league opens, and the Rules tab inside every league shows the numbers in force.
The fine print
If your player's game is postponed after lock, the pick is voided and the player is not used up.
Days with fewer than 4 games are optional: no pick means no points and no penalty.
A missed day scores zero for that slot. Turn on auto-pick and the league fills an empty slot 30 minutes before first pitch with your highest-ranked unused player who plays that day. You also get a reminder two hours before first pitch when a slot is empty.
You have 2 mulligans: un-use a player whose locked pick was ruined by a scratch or rainout with no alternate.
Doubleheaders: both games count; the pick locks at game one.
Ties break by days played, then by the best single day.
How to play it well
Roughly 150 pitchers start regularly, so a 180-day season forces relievers by August. Save and hold count, so closers are real picks.
The top 100 hitters run out around midseason. That is the strategy, not a bug: know when to burn a star.
Matchup beats name. A good hitter against a bad lefty in a hitter's park is often the better pick than a star in a pitcher's park.
