Flood v. Kuhn, 407 U.S. 258 (1972), was a decision by the Supreme Court of the United States that preserved the reserve clause in Major League Baseball (MLB) players' contracts. By a 5–3 margin, the Court reaffirmed the antitrust exemption that had been granted to professional baseball in 1922 under Federal Baseball Club v. National League, and previously affirmed by Toolson v. New York Yankees, Inc. in 1953. While the majority believed that baseball's antitrust exemption was anomalous compared to other professional sports, it held that any changes to the exemption should be made through Congress and not the courts.
