Baseball arbitration is a form of binding arbitration in which each side submits a single final dollar figure and the arbitrator must pick one of the two numbers, with no authority to split the difference or propose anything in between. The format takes its name from Major League Baseball’s 1973 salary negotiations and now appears in commercial contracts, construction disputes, and federal healthcare billing under the No Surprises Act.
How the Standard Format Works
Each party submits one dollar figure representing what it believes the dispute is worth. The arbitrator reviews evidence, hears arguments, and then selects one of those two numbers. There is no middle ground. The arbitrator cannot adjust either offer, blend them, or write a third figure. If one side submits $100,000 and the other submits $50,000, the award will be exactly one of those amounts.1Major League Baseball. Salary Arbitration
The mechanism was designed to answer a persistent complaint about conventional arbitration: that arbitrators tend to “split the baby” by landing somewhere between the two positions regardless of the evidence. When an arbitrator can only pick one number, a party with an extreme position doesn’t pull the middle toward itself. It risks losing outright. Both sides face pressure to be reasonable, and disputes often settle before the hearing because the gap between offers narrows sharply during preparation.
Variations
Night Baseball Arbitration
Night baseball arbitration keeps both offers hidden from the arbitrator during the hearing. Each side submits its final number in a sealed envelope. The arbitrator evaluates the evidence independently, arrives at a dollar figure, and only then opens the envelopes. Whichever offer sits closest to the arbitrator’s independent valuation becomes the binding award.2CPR Dispute Resolution Services. Final Offer or Baseball Arbitration
Because the arbitrator doesn’t know what the offers are, there is no anchoring bias. If the arbitrator independently values a claim at $75,000 and the sealed offers are $60,000 and $100,000, the $60,000 offer wins. A party that overshoots by even a dollar more than the other side undershoots will lose.
High-Low Arbitration
In high-low arbitration, the parties privately agree on a floor and a ceiling before the hearing. The arbitrator doesn’t know about these boundaries and renders a decision normally. If the award falls within the agreed range, it stands. If it falls below the floor, the losing party pays the floor amount. If it exceeds the ceiling, the winning party receives only the ceiling. Some practitioners combine high-low parameters with standard baseball rules, so the arbitrator picks one offer but neither party can win or lose beyond the agreed range.
Where Baseball Arbitration Is Used
Beyond its origin in professional baseball salary disputes, the format now shows up in commercial contracts, construction disputes, and one prominent federal program. The No Surprises Act, effective January 2022, adopted baseball-style arbitration to resolve billing disagreements between out-of-network healthcare providers and insurers. When the two sides can’t agree on a payment amount for a surprise medical bill, either can trigger an independent dispute resolution process. A certified IDR entity acts as the arbitrator, selecting either the provider’s offer or the insurer’s offer with no option to pick something in between.3Federal Register. Requirements Related to Surprise Billing
The IDR entity starts by considering the qualifying payment amount, which is generally based on the insurer’s median in-network rate for that service in the same geographic area. It then weighs additional credible information either party submits, such as the provider’s training, the complexity of the case, or market conditions. If the IDR entity relies on factors beyond the qualifying payment amount, its written decision must explain why those factors weren’t already reflected in that baseline figure.3Federal Register.

The system follows a “loser pays” model for IDR fees, which raises the stakes for both sides. The volume of disputes filed since 2022 has overwhelmed the process, making it difficult for IDR entities to meet the 30-day statutory deadline for decisions.
Preparing the Final Offer
The final offer is the entire case compressed into a single number, so everything rides on getting it right. Preparation starts with assembling evidence that justifies your figure: independent appraisals, comparable transaction data, market benchmarks, expert reports, and financial records. The goal isn’t just to support your number. It’s to make the opposing number look unreasonable by comparison. Arbitrators in baseball proceedings routinely say they’re looking for the offer that most closely reflects the evidence.
A common mistake is treating the final offer like an opening bid in a negotiation, building in room to come down. That instinct is exactly backward. Padding your number doesn’t give you leverage; it gives the arbitrator a reason to pick the other side’s figure. The most effective offers are ones a neutral observer would look at and call about right.
The enforceability of the process rests on the Federal Arbitration Act, which makes written agreements to arbitrate “valid, irrevocable, and enforceable” in contracts involving commerce.4Office of the Law Revision Counsel. 9 U.S. Code 2 – Validity, Irrevocability, and Enforcement of Agreements to Arbitrate If your contract includes a baseball arbitration clause, a court will generally compel the process rather than allow litigation. Clause language matters. Well-drafted clauses specify the administering organization, the timeline for submitting offers, whether rebuttals are permitted, and the qualifications required of the arbitrator.
The Hearing
Hearings in baseball arbitration tend to be more focused than conventional arbitration because both sides are arguing for a specific number rather than exploring open-ended liability theories. Each party presents evidence, explains why its figure is reasonable, and attacks the other side’s number. Many baseball arbitration clauses impose time limits on presentations, sometimes as short as one hour per side.
Discovery is far more limited than in court litigation. Requests must be specific in terms of time frame, subject matter, and the people or entities involved. Broad demands for “all documents related to” a topic are routinely denied. Electronic discovery follows similar constraints, with production generally limited to materials used in the ordinary course of business.
The Award
Under standard commercial arbitration rules, the arbitrator issues a written award within 30 calendar days after the hearing closes. The award identifies which party’s offer was selected and is immediately binding. There is no automatic appeals process that delays enforcement.
To convert the award into an enforceable court judgment, either party can apply to a federal court for a confirmation order within one year of the award. Once the court confirms it, the award carries the same weight as any other court judgment, including the ability to garnish wages, levy bank accounts, or place liens on property.5Office of the Law Revision Counsel. 9 USC 9 – Award of Arbitrators; Confirmation; Jurisdiction; Procedure Payment deadlines depend on the arbitration agreement and the administering organization’s rules. Thirty days from receipt is a common standard, though some agreements allow up to sixty.
Challenging an Award
Courts almost never overturn arbitration awards, and the grounds for doing so are narrow. Under the Federal Arbitration Act, a court can vacate an award only for:
- Corruption or fraud in obtaining the award
- Evident partiality, meaning a conflict of interest or demonstrated bias by the arbitrator
- Misconduct, such as refusing to postpone a hearing when justified, refusing to consider material evidence, or otherwise prejudicing a party’s rights
- Exceeding authority, meaning the arbitrator went beyond the powers granted by the arbitration agreement or failed to produce a definitive award on the submitted issue
Disagreeing with which offer the arbitrator picked is not a valid ground. The whole point of the format is that the arbitrator selects one number, and “I think they picked wrong” doesn’t meet the threshold for vacatur. A party seeking to vacate must file the motion within three months after the award is delivered.7Office of the Law Revision Counsel. 9 U.S. Code 12 – Notice of Motions to Vacate or Modify; Service If the court does vacate and the original arbitration agreement’s deadline hasn’t expired, the court can order a rehearing before the same or new arbitrators.
Confidentiality and Taxes
Arbitration is private, but private is not the same as confidential. No federal law automatically makes arbitration proceedings or awards confidential. The institution’s staff and arbitrators typically have ethical duties not to disclose case information, but the parties themselves are generally free to discuss the proceedings unless they’ve signed a separate confidentiality agreement.8American Arbitration Association.

Arbitration awards are taxable income under the same rules that apply to court judgments and settlements. The IRS treats all income as taxable unless a specific provision of the tax code says otherwise.9Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined For most commercial baseball arbitration awards involving contract disputes, business valuations, or payment disagreements, the full amount is taxable. The main exception involves damages for physical injuries or physical sickness, which are excluded from gross income whether received as a lump sum or periodic payments.10Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness The exclusion does not cover punitive damages, emotional distress unrelated to a physical injury, or lost profits in a business dispute. Awards for non-physical injuries like defamation or breach of contract are fully taxable.11Internal Revenue Service. Tax Implications of Settlements and Judgments
