Free Online MLB Career Simulator
The MLB Career Simulator is a decision-driven minigame: you create your player, pick one of the 30 major league teams, and simulate season after season. Along the way you'll face injuries (surgery and miss the season, or play through the pain?), free-agency offers when your contract expires, and eventually the choice to retire or play one more season. Your decisions, your overall rating, and a bit of luck decide whether you end up hoisting the World Series trophy or a role player. There's no sign-up or server: your name and your career history are saved only in your browser's storage.
