MLB Front Office

Real 2026 rosters. Real tax-line pain. October does not forgive.

Take over a baseball front office

Real 2026 rosters from MLB's own data, rated off real 2025 stats. Manage the payroll under the tax line, survive the 162, then October: Wild Card, Division Series, LCS, World Series. Saves automatically.

MLB Front Office: the GM Sim

Take over a real MLB club with its actual 2026 roster, every player rated off real 2025 stats pulled from the league's own data. Manage the payroll against the luxury tax line, DFA dead weight, sign free agents, swing trades the AI weighs on age, position and rating, then grind the 162 in simulated stretches. Win your division for a bye, survive the best-of-3 Wild Card round, the Division Series, the LCS and the World Series. Draft prospects whose scouting grades can lie, ride aging curves and retirements, and stack rings across unlimited saved seasons.

Running a front office sounds fun until the payroll page loads. This is a full GM sim of the real 30 team league, every player rated off real 2025 stats.

The problems are real: a tax line that will not move, aging veterans, scouts who lie, and 29 rivals that never stop churning.

How to play MLB Front Office

  • Choose a franchise and inherit its actual lineup, rotation and bullpen.
  • Read the ownership mandate: a stacked roster is told to win the World Series, a mid one to make October, a thin one to hit an honest win number. It resets every offseason.
  • Work the roster: DFA dead weight, sign free agents, and take trades to the phone, where the other GM counters with pick demands and lesser returns instead of a flat yes or no.
  • Play the 162 in stretches: each round simulates about a week and a half of baseball, 27 rounds total, with a live read on whether you are on pace.
  • Make October. Division winners seed 1 to 3, three wild cards follow, and the top two seeds skip the Wild Card round.

    • Rules to know

  • The tax line starts at 244 million, matching the real 2026 threshold, and it is a hard cap, rising 3 percent a season.
  • Playoffs use the real format: best-of-3 Wild Card, best-of-5 Division Series, best-of-7 LCS and World Series.
  • Trades weigh rating, age and position, with premiums on aces, shortstops and catchers.
  • You hold 2 picks a year, and scout grades carry error. True ratings show only after you pick.
  • Injuries cost one to four rounds on the IL, and your franchise saves automatically.
  • Trust upstairs runs 0 to 100: beat the mandate and it climbs, miss it and it falls, a ring fixes almost anything, and at zero you are fired and the save ends.

    • Example walkthrough

    You take a club 8 million under the line. A DFA clears a bloated deal, the savings sign a 79 rated reliever, and your aging ace becomes a 26 year old shortstop.

    You win the division, take the bye, and still lose the LCS in six. Next spring your 84 grade pick arrives as an 80. Scouts, man.

    Strategy tips

  • Payroll room is a roster spot. One dumped albatross often buys two useful arms.
  • Age drives value. A decent 24 year old can outpull a 33 year old star, so sell veterans early.
  • The sim weighs your lineup most, then rotation, then bullpen. Spend in that order.
  • October is a variance machine, so build for repeat trips, not one all-in year.

    • MLB Front Office FAQ

    Are the contracts real?

    Rosters and ratings come from real data, but every salary, contract and transaction in the sim is fictional.

    Can I go over the tax line?

    No. Moves that break the line do not go through. That squeeze is most of the job.

    Why did my trade get rejected?

    The AI wants a premium on rating, age and position. Add one of your 2 picks, or offer someone younger.

    Can I get fired?

    Yes. Ownership grades the mandate every season and tracks trust from 0 to 100. A 70 win season on a win-the-World-Series payroll costs real trust, and at zero the save ends and you take another job.

    Is MLB Front Office free to play?

    Yes. MLB Front Office is free to play on DoUKnowBall, right in your browser. No download and no signup needed.
