Definition
Baseball, as a legal term of art, appears most prominently in two distinct contexts:
1. BASEBALL ARBITRATION (also called "final-offer arbitration"): A form of binding arbitration in which each party submits a single proposed outcome and the arbitrator must choose one figure in its entirety, without modification or compromise. The arbitrator has no authority to split the difference or craft an independent remedy. The name derives from the salary arbitration procedure used in Major League Baseball labor relations, where the mechanism was developed and institutionalized.
2. THE SPORT AND ITS LEGAL EXCEPTIONALISM: Baseball as an organized professional sport occupies a unique position in American law due to a Supreme Court-recognized exemption from federal antitrust law — an exemption that has no parallel in other professional sports and that has been modified but not eliminated by statute. This makes the sport itself a recurring subject in antitrust, labor, and sports law research.
Common Language
Modern common usage (Wiktionary): A sport common in North America, the Caribbean, and East Asia in which a nine-person team scores runs by striking a ball and running counter-clockwise among four bases; also the ball used in the sport.
Historical common usage (Webster's 1913): A game of ball, named for the bases or bounds — four in number — which designate the circuit each player must endeavor to make after striking the ball.
The gap between common and legal meaning is significant in one direction: a researcher encountering "baseball arbitration" in a contract, labor agreement, or ADR context will find nothing in common usage to prepare them for the procedural constraint at the term's core. The all-or-nothing structure of baseball arbitration is a specific legal mechanism, not merely a metaphor for the sport.
Common Confusion
Baseball arbitration is frequently confused with conventional interest arbitration, in which the arbitrator retains broad discretion to fashion an award. The confusion matters practically: drafters who intend final-offer arbitration must specify it explicitly, and courts interpreting arbitration clauses have sometimes declined to infer it. The term "baseball arbitration" is informal and not universal — some jurisdictions and drafting traditions prefer "final-offer arbitration" or "last-best-offer arbitration." These terms are functionally synonymous but not always treated identically in every procedural context.
Recognized Forms
/SUBTYPES
Night baseball arbitration: A variant in which neither party knows the other's final offer before submission, and the arbitrator issues an independent award; the party whose submission is closest to the award wins. Rare in practice but recognized in ADR literature.
Salary arbitration: The specific application in Major League Baseball labor relations, governed by the MLB-MLBPA Collective Bargaining Agreement, in which eligible players and clubs submit competing salary figures and a panel selects one.
Why It Matters in Research
Baseball arbitration is increasingly common outside sports law — it appears in commercial contracts, real estate disputes, regulatory proceedings, and insurance valuation clauses. A researcher who encounters the term in a non-sports document should not assume a sports law context; trace the arbitration clause itself.
The antitrust exemption for professional baseball is a discrete and well-developed area. The exemption traces to a trio of Supreme Court decisions and was partially addressed by the Curt Flood Act of 1998, which extended antitrust protections to major league players (but not to the minor leagues, franchise relocation, or other league business). Researchers in antitrust law should be aware that this exemption is an anomaly: other professional sports — football, basketball, hockey — are not categorically exempt, though labor law doctrines (the "non-statutory labor exemption") create overlapping complexity across all sports.
Historical sources including Bouvier's treat baseball purely as the sport, with no legal content attached. This is expected: the antitrust exemption litigation developed in the twentieth century, and baseball arbitration as a formal mechanism emerged from collective bargaining in the 1970s. Any research into the legal dimensions of baseball will outrun nineteenth- and early twentieth-century dictionary resources entirely.
Historical Dictionary Support
Bouvier's Law Dictionary reproduces a Standard Dictionary definition of baseball as a game played with bat and ball. There is no legal content in the entry. This reflects the state of sports law before professional leagues became subjects of sustained federal litigation. Bouvier's inclusion of the term at all is likely attributable to the sport's cultural prominence rather than any legal significance recognized at the time of compilation.
Webster's 1913 similarly treats baseball as a popular game defined by its base-running structure. Neither source anticipates the term's later legal life. Researchers should treat historical dictionary entries for baseball as essentially uninformative for modern legal research purposes and consult antitrust, labor law, and ADR-specific sources instead.
Jurisdictional Note
The antitrust exemption for professional baseball is a creature of federal law and applies nationally; state antitrust claims against MLB have generally been preempted. Baseball arbitration as a contractual mechanism is jurisdiction-neutral — it can appear in any agreement governed by any state law — but enforcement of arbitration awards is governed by the Federal Arbitration Act or applicable state arbitration statutes depending on the transaction.
