MLB Pushes Nationwide Ban on Micro Prop Bets Integrity Risk

Major League Baseball is moving to eliminate micro prop bets wagers tied to individual in-game actions amid mounting concerns over integrity risks and potential match-fixing. Ohio Governor Mike DeWine revealed that MLB Commissioner Rob Manfred is coordinating with other major sports leagues to pursue a federal ban covering all states. DeWine added that agreements with major sportsbooks to remove these markets are already nearing completion.

Micro prop bets include wagers on outcomes like the first pitch result or how many outs a pitcher records in a single inning. DeWine argues that such markets create vulnerabilities because they focus on individual player performance rather than team results, making insider manipulation more feasible. He stressed the need for swift action, stating that Ohio could take independent steps if federal measures stall.

The push follows heightened scrutiny across professional sports, including a recent federal investigation into an illegal betting operation linked to NBA personnel. Ohio’s debate intensified earlier this year after Cleveland Guardians pitchers Luis Ortiz and Emmanuel Clase were briefly benched due to suspicious betting concerns, though no violations were found.

DeWine has previously supported restrictions to protect athletes and competition integrity, backing Ohio’s 2024 ban on college-player prop bets after reports of harassment and threats against student-athletes. For similar rules to apply to professional sports in Ohio, the Joint Committee on Agency Rule Review would need to consider the proposal, though the state could act faster if leagues formally request it.

Calling micro props a “growing weak spot” in regulated betting, DeWine emphasized prioritizing fair play over short-term sportsbook revenue.
