  • $264M — Second threshold (+12% added)
  • $284M — Third threshold (+13% added)

  • Repeat offenders face higher rates

What Makes MLB Different

No hard cap.
No floor.
Your call.

MLB lets you go as high as you want — you just pay penalties. This creates a different strategic game than the NFL or NBA.

  • Free agency: 6 years of service time
  • Arbitration: years 3-5 (or Super Two)
  • Club control: first 3 years, pre-arb
  • No restructured deals — money is money
  • International bonus pool restrictions
