Fantasy baseball without the homework.
You don't need to know anyone's WHIP. No need to understand WAR or OPS+ or BABIP. No setting a pitching rotation, streaming relievers, or agonizing over your utility slot.
You need to know one thing: did your guy hit a home run?
Wallop strips fantasy baseball down to the thing everyone at the ballpark stands up for: the longball, the dinger, the wallop.
There are no weekly matchups. No head-to-head records. No wins and losses. It's a season-long race to the highest points total—and with postseason multipliers, the lead can change on any October swing.

How it works
- Draft Pick six MLB hitters in a snake draft with your league. No positions, no pitchers.
- Set your lineup Four active, one bench, one DL. Pre-set your lineup for the week or fiddle with it daily to your heart's content.
- Score home runs Every home run an active player hits earns a point. Grand slams, walk-offs and postseason homers are worth more.
- Play through October Grab players likely to make the postseason—bonus points mean anyone can come from behind to win it all.

The fine print
- What is the Postseason Classic?
- A free October game. Pick nine hitters across four tiers before the playoffs start. Every home run they hit in the postseason scores for you, and later rounds count more. No league needed. Picks lock at first pitch on Sep 29.
- How much time does this take?
- A few decisions a week. Set your lineup on Monday, adjust your waiver list by Sunday. That's it.
- How many people can play?
- 3 to 10 per league. With no head-to-head matchups, odd numbers work just as well as even.
- What does it cost?
- Season leagues are $26 per league. One person pays, everyone plays. The Postseason Classic is free.
- When does the season start?
- The 2027 season opens in March. You can form a league and draft any time before Opening Day. Until then, the Postseason Classic is open to anyone. Want one email when leagues open? Leave your address above.
- This sounds familiar. Where do I know it from?
- Probably a Grantland article from 2011 about a family's home run league. That ruleset is our gameplay touchstone — a format tested across real seasons with real arguments about roster moves. We built Wallop to let anyone run that league.
- Are there public Wallop leagues?
- No. Wallop is meant to be more personal than being dumped into a draft room with a bunch of strangers. It's a low-key excuse to stay in regular touch with friends, family or coworkers. At minimum you need only two contacts who are vaguely interested in baseball to form a league.
- Can scoring for my Wallop league be customized?
- Not at this time. Wallop is opinionated in its gameplay. We think it's an engaging set of defaults. Plus, when everyone plays by the same rules — later in the season — it will allow for cross-league team leaderboards (based on league size).
- Where are the full rules?
- The Official Rulebook has everything — scoring tables, roster slots, waiver mechanics, tiebreakers.
