MLB My Career: Baseball Career Simulator

Build a fictional prospect and live a whole MLB career inside the real league. Archetypes drive realistic season lines, choices drive everything else, and the legacy verdict at the end tells you exactly what your career meant.

Draft day, age 21, one made-up prospect: you. My Career drops a fictional player into the real 30 team league to live every season from draft hype to farewell tour.

Your archetype shapes the ride. A Flamethrower touches triple digits while his elbow prays nightly. A Crafty Lefty ages forever. A Masher is 45 homers or bust.

You build your player's actual face before the draft, and there is a dirty side waiting whenever you want it. A camera in center field and a trash can behind the dugout, something on the glove that adds 300 rpm, a clinic in Florida that ships in unmarked boxes, tipping pitches to a man who likes first innings. Every dirty choice raises a hidden commissioner meter, and this is the sport that hands out lifetime bans.

How to play MLB My Career, a free baseball career simulation game

Creating your player and picking an archetype

  • Create your player: name, one of 11 positions (SP, RP, C, 1B, 2B, 3B, SS, LF, CF, RF, DH), and one of 33 archetypes, from Flamethrower to The Framer to Pure Masher.
  • Choosing today's league or the 2004 throwback

  • Pick your league: today's MLB, or the 2004 throwback with the Expos in Montreal, the Anaheim Angels, the Florida Marlins and the Devil Rays.
  • Building your look and spending in seven aisles

  • Build your look, then spend the money in 7 aisles including a shady one that only appears once you have something to hide.
  • Managing the Bank between seasons

  • Open the Bank between seasons. Savings pays 2.5% a season and never loses, five things you can put money into each have a price that moves every season whether you look or not (a fund, flats back home, two shares and a coin that halves as often as it doubles), the statement keeps your last 12 moves, and the card school in the clubhouse is one sitting a season on odds that are printed before you sit in.
  • Reading the News box and the rival's card

  • Read the News box. The paper writes up every season in your own position's stat, the SocialGram shows followers read off your fanbase with three fan comments under the latest post, and the rival's card keeps the head to head against the player drafted the same year as you.
  • Collecting badges in the Trophy Case

  • Collect badges in the Trophy Case: 26 of them, from a first ring and Rookie of the Year to 500 home runs, 3,000 strikeouts and $100M to your name, each lit the moment the facts of your career say so.
  • Answering your phone on the baseball calendar

  • Answer your phone. Texts from your agent, the manager, the GM, a teammate or your mom land on the beats of the baseball year: draft day, spring training, the All-Star break, the trade deadline, September, October if you get there, the offseason, an arbitration winter and the winter you hit free agency. Every text says which beat and which year it came in on, and how you answer moves your karma, morale, fanbase or bank.
  • Making the call when your rival forces one

  • Some seasons your rival puts a decision on your plate instead of a story: benches clearing that you can answer or calm down, a debate show offering real money, a youth clinic his foundation wants you to co-host, an All-Star vote his club is buying ads for. Every button prints exactly what it moves, and a gamble prints its odds.
  • Entering the draft and playing full seasons

  • Enter the draft, land on a real club, and play seasons for full stat lines: average, homers and RBI, or wins, ERA and strikeouts.
  • Open Career Log and pick a year to review its saved overview, regular season and postseason. Changes compare with the previous saved season; older missing values say Not recorded. Back to seasons returns to the year tiles, and Review seasons is available after retirement.
  • Climbing the lineup card from the bench

  • Check the lineup card. Top ten picks play from Opening Day; everyone else fights the veteran in spring, with bench bats and long-relief arms waiting on spot starts until the job flips. Relievers climb their own bullpen ladder instead.
  • Handling offseason events

  • Handle the winter, up to three decisions one card at a time: winter training, surgery calls, trade rumors. Only the first card can move your rating, and a card you just saw rests for a while (press moments follow your season, so those can come right back).
  • After a normal offseason choice, the result shows the actual changes. Expand it for any extra changes, then Continue opens the next card, or takes you back to your career after the last one, without applying the choice again.
  • Hitting the open market and closing your career

  • When team control ends, hit the open market for real: competing offers from named clubs with their own money, length and roster quality, and one push for more on any of them.
  • Stack awards and rings, fight aging, answer the retirement talk when the rating slips, and retire to a verdict and the Hall of Fame ballot.
  • MLB My Career rules for aging, money and the press

    Starting at 21 with six years of control

  • You start at 21 in 2026 with 6 years of team control before free agency. The throwback starts in 2004 instead, inside a sealed 30 team league verified against the real season, with 2004 sized contracts.
  • Tracking morale, fanbase and health

  • Three meters run your life: morale, fanbase and health. Low health means shortened seasons.
  • How your rival's choices work

  • Any season your rival stays out of the news carries a 45% chance of a rival choice instead, never both in one season, and you meet every choice once before one comes back. Each button moves exactly what it prints: morale, fanbase, net worth, karma or the heat of the feud. Morale goes straight into next season's numbers, at the plate or on the mound.
  • How the phone's calendar works

  • Texts only arrive on beats your season really had. No October texts in a year your club went home in September, arbitration only in the winters after your third, fourth and fifth seasons while your deal still has years on it, free agency only the winter your deal runs out, and draft day's text lands before you see a pitch. One text a beat, up to three a season, fewer while old ones sit unanswered, and the same text never comes twice in a career.
  • The season the game retires you (42, 21 seasons, or a rating that craters) sends nothing about a year you will not play: no winter ball offer, no bat and glove deal, no arbitration or free agency talk.
  • How real playing time gets decided

  • The lineup card is real: a bench season is about half the games, a spot starter gets a dozen turns, springs have memory both ways, and signing with a stacked contender can cost a mid player the everyday job.
  • What the press asks after each season

  • The press reads your actual season: a ring puts you on the podium, missing October badly puts you in the scrum, a bench year brings the role question. Three answers each time, safe, honest or fiery, and fiery gambles your fanbase for real.
  • Growing to your potential, then aging

  • Players grow toward their potential through age 26 and decline from 32 on, faster after 37.
  • Retiring at 42 or walking away at season 6

  • Retirement hits at 42, after 21 seasons, or when your rating collapses. Before that, from 32, slipping 8 points off your best (or down to 68) brings the talk: retire now, one more year, or a farewell season. You can walk away after season 6.
  • The Bank's rules on fees, floors and card odds

  • Money has rules of its own. There is a 1% fee on both sides of every trade and a $100k floor in the account that cannot be invested away; a season that leaves you under the floor is covered out of savings first, then by a forced sale of holdings at whatever the price is that day. Cards win 42% of hands and a win pays 1.15x the stake, the most you can stake is $50k or 4% of your cash, and once you are $500k down for your career the guys stop dealing you in for good. Keep sitting in while you are losing and somebody at home notices, which costs morale and fanbase.
  • What the fans nag your position for

  • The fans nag you for the thing your position is judged on and never the other way round: a starter hears go deeper into games, a closer hears shut the door, a catcher hears more pop from behind the plate. No arm is ever asked for home runs, no bat is ever asked for an ERA, and the three spots with no speed in them are never asked to run.

  • MLB My Career walkthrough: from draft day to a Hall of Famer verdict

    Reading an actual capped change

    Say Health is 98 before a recovery choice that adds 10. The 100 cap makes the result 98 to 100, so the card shows +2. Continue moves you on (to the next card, or back to your career after the last one) with Health still at 100.

    Drafting a Slugging Shortstop at 12th overall

    You build a Slugging Shortstop who goes 12th overall. Year two brings the breakout, year five a ring. When control ends, the hometown club offers a discount while the market whispers bigger money elsewhere.

    Chasing the money to a Hall of Famer verdict

    You chase the money, the new fanbase starts cold, and the decline grinds. At 38 you retire with 430 homers, a ring and five All-Star nods. Verdict: Hall of Famer.

    When the benches clear on your rival

    Both benches empty after a pitch up and in, your rival is first out of his dugout, and the card asks what you do about it. Answer it on the field heats the feud and usually pays Morale +8, but it carries a 30% chance you are the one who gets tossed (Morale -5, Fanbase -5, Net worth -$100k). Play peacemaker on camera is Fanbase +5, Karma +5 and the feud cools. You pick say nothing and watch the tape: Morale +6, the feud heats up, and those six points ride into next season's numbers.

    MLB My Career tips for durability, training and surgery

    Why durability wins careers

  • Durability wins careers. Steadier archetypes stay on the field while flashy builds collect injury notes.
  • Spending winter training while you are young

  • Spend winter training on your ceiling while young. From 32 it quietly turns into maintenance, so bank gains early.
  • Taking the elbow surgery as a pitcher

  • Pitchers, take the elbow surgery. Playing through a bad MRI turns every start into a gamble.
  • MLB My Career FAQ: verdicts, free agency and the Bank

    What decides the legacy verdict?

    One score from rings, MVPs or Cy Youngs, All-Star nods, seasons and stats. Reach 500 and Cooperstown calls. At 900 you are inner circle, first ballot.

    Can I change teams?

    Yes. Low morale can trigger trade rumors where you ask out, and when the contract expires you get a real market: named clubs bidding with their own money, years and roster quality, plus your own club's re-sign number. You can push any offer for more once, and your own club never walks away.

    Is the player real?

    No, the prospect is fictional on purpose. The 30 teams are real, the career is yours.

    Why am I on the bench?

    Because the veteran is better, for now. Late picks usually open as bench bats or long-relief arms behind an incumbent whose level tracks the roster. Grow your rating and you take the job in spring. Relievers never sit; the bullpen ladder is about whether you become the closer, which is your archetype's fight.

    Can I start in a different era?

    Yes. The create screen has a 2004 throwback: the league in the Expos' last Montreal summer, with the Anaheim Angels, the Florida Marlins, the Tampa Bay Devil Rays and the Oakland Athletics. An era career never meets a franchise identity that did not exist then.

    What is in the Bank?

    Four tabs. Account holds your cash, a savings account that pays 2.5% a season, and a statement of your last 12 moves. Market is five prices that move every season, each with its own risk word and a read on whether it is cheap or dear against what it usually goes for. Cards is the clubhouse card school, one sitting a season, on odds the screen prints before you play. Shop is the 7 aisles. It is the same engine Soccer Career's phone runs on, in dollars.

    Who is my rival?

    A generated player drafted the same year at your position. He plays his own seasons on the same scale you do, can win a ring before you and retire before you, and the head to head is kept for good. He is fictional, like your own player, so no real player's career is being simulated.

    How do I earn badges?

    By doing the thing. Each of the 26 badges is a test on the facts of your career, checked every time you open the case: a ring, an MVP or a Cy Young, 500 home runs, 300 wins, a million dollars to your name. The single season badges sit under the real records because the sim's own ceilings do: 50 home runs against the record 73, a .330 average when nobody has hit .400 since Ted Williams' .406 in 1941, and 50 stolen bases against the record 130. The strikeout badge is the real 3,000 club, and the career record there is Nolan Ryan's 5,714.

    Is MLB My Career free to play?

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