Perfect Season all-time draft Refreshed Jun 12 06:00 AM ET
Mithrandir · Perfect Season

Can you build a 162-0 team?

Spin a random franchise and era, draft one player to fill a roster spot, and keep going until you've built a full 25-man-ish squad: nine in the lineup, a five-man rotation, and a bullpen. Then we run your all-time roster through an era-adjusted simulation to see how close you get to a perfect season.

Build an all-time roster, one spin at a time, and see if it can go 162-0.
The math says it is barely possible: even drafting flawlessly, only about 2 to 4% of all-time rosters run the table. Draft at random and you will basically never do it, yet you will still average around 114 wins (better than nearly every team in real MLB history). Perfection takes skill and luck.
The trend

Yes, we saw 82-0 too.

The viral NBA game 82-0 (draft five legends across eras, see if they go undefeated) is a blast, and a few quick baseball knockoffs have popped up since. We loved the idea and wanted to do a real baseball version: deeper roster, deeper data, and an actual simulation behind the record instead of a hand-wavy rating.

Our twist

Built on the whole site's engine.

  • Every player-season since 1876 (45,000+), not a short modern list.
  • Era-adjusted value: each player is scored against his exact league-year (OPS+ / ERA+), so 1968 and 2019 compete fairly.
  • A real record simulation, the same projection approach we use across Mithrandir.
  • Position flexibility with honest trade-offs (more below).
  • A full analytical breakdown of your season afterward, not just a number.
How to play

Spin, draft, simulate.

  1. Spin a random franchise and era.
  2. Draft one of that team-era's players into an open roster spot.
  3. Fill the whole squad: 9 in the lineup, a 5-man rotation, and a 3-arm bullpen (17 picks). The spin spreads you across eras for variety.
  4. We run your roster through the era-adjusted sim and reveal your record.
The twists & the cool stuff

What to watch for.

  • Position flexibility: a player can cover spots he really played, and can stretch to easier ones (a shortstop sliding to second) at a small WAR penalty. A bad defender stays locked to his corner.
  • A live field view: your picks drop into their real positions as you draft.
  • A post-draft story: where your team was strong or weak, your best and worst picks, and how you stack up against the best real teams ever.
  • Full history, full chaos (v1): the pool is every qualified team ever, including short-lived 1800s clubs with only a couple of qualified players, some barely a win above replacement. A rough spin can hand you a weak pick. For this first version that is part of the difficulty. We may add a filter later.
