Prop betting in Ohio faces an uncertain future amid a developing scandal involving professional baseball players. Following an investigation into suspicious wagers by Cleveland Guardians players, Governor Mike DeWine has called for immediate action to outlaw certain types of proposition bets throughout the state. The controversy centers specifically on sports betting markets that allow gamblers to wager on individual player actions rather than game outcomes.
The unprecedented move comes as MLB officials placed two Guardians players on paid leave after unusual betting patterns were detected. Meanwhile, Ohio regulators are already considering new restrictions on sportsbooks operating in the state. However, the betting industry has pushed back against these proposed limitations, arguing that education rather than prohibition would better address integrity concerns in the growing sports gambling market.
Governor DeWine demands emergency ban on prop bets
DeWine took decisive action on July 31, declaring that proposition betting poses a serious threat to sports integrity and calling for its immediate removal from the state's gambling landscape. His announcement came directly in response to Major League Baseball's investigation into two Cleveland Guardians pitchers.
Statement issued following MLB investigation
DeWine explicitly referenced the ongoing "sports betting investigation" into Guardians pitchers Luis Ortiz and Emmanuel Clase as a catalyst for his demand 1. Both players were placed on non-disciplinary paid leave by MLB through August 31st.
"The evidence that prop betting is harming athletics in Ohio is reaching critical mass," DeWine stated in his official release. "First, there were threats on Ohio athletes, and now two high-profile Ohio professional athletes have been suspended by Major League Baseball as part of a 'sports betting investigation'".
DeWine highlighted particular concerns about micro prop bets - wagers on highly specific events within games that are completely controlled by individual players. According to reports, Clase's involvement in the investigation stems from two pitches he threw in separate games in June, where an abnormal amount of money was bet on the closer to either hit the batter or throw a ball.
The governor's statement characterized proposition betting as a failed experiment across the country, asserting that "the harm to athletes and the integrity of the game is clear, and the benefits are not worth the harm".
Call to Ohio Casino Control Commission for immediate action
DeWine formally directed his request to the Ohio Casino Control Commission (OCCC), asking them to "remove all prop bets from the Ohio marketplace". Additionally, he urged the OCCC to eliminate prop bets from the list of legal wagers that can be placed under Ohio's contractual rules for operators.
The governor's concerns about proposition betting predate the current scandal. He specifically mentioned threats against University of Dayton basketball players that emerged shortly after Ohio's sports gambling laws took effect in January 2023 1. Those incidents eventually led the OCCC to enact rules in February 2024 that banned collegiate prop bets.
Furthermore, DeWine announced plans to seek broader support for his initiative, stating he would ask commissioners and players unions from major professional sports leagues, including MLB, NFL, NBA, WNBA, NHL, and MLS, to support the effort to "ban prop betting to ensure the integrity of their leagues".
Executive Director Matt Schuler clarified that while the OCCC is reviewing all types of microbets currently offered by the state's books across all sports, DeWine's request was specifically focused on in-game, player-specific microbets, not necessarily all player prop bets. The commission subsequently began drafting a rule to prohibit certain player-specific prop bets, though the specific limitations remain unclear.
Notably, MLB Commissioner Rob Manfred had previously expressed similar concerns, questioning whether certain types of wagers are necessary, especially those involving "one single act" that doesn't necessarily affect game outcomes 5.
MLB investigates Guardians players over suspicious wagers
Major League Baseball's integrity investigation has cast a shadow over the Cleveland Guardians' season as two key pitchers face scrutiny for potential connections to suspicious gambling activity. The probe marks a significant escalation in baseball's ongoing battle with sports betting concerns.
Luis Ortiz and Emmanuel Clase placed on paid leave
MLB placed right-hander Luis Ortiz on non-disciplinary paid leave on July 3, making him the first Guardians player implicated in the sports betting investigation. A few weeks later, on July 28, three-time All-Star closer Emmanuel Clase also found himself placed on identical non-disciplinary paid leave. Both players will remain on leave through at least August 31, effectively sidelining them during the team's playoff push.
Clase, 27, represents a particularly significant loss for Cleveland. The dominant reliever has established himself as one of baseball's premier closers, finishing third in AL Cy Young voting last year when he posted a remarkable 0.61 ERA over 74⅓ innings 7. This season, Clase has recorded 24 saves while maintaining a 3.23 ERA.
The Guardians organization has since cleared out the lockers of both pitchers, suggesting internal preparations for extended absences. In an official statement, the team noted that "no additional players or club personnel are expected to be impacted" by the investigation.
Unusual betting flagged on specific pitches
At the center of the investigation are two specific pitches thrown by Ortiz that received abnormally high betting activity. The suspicious wagers focused on Ortiz's first pitches in select innings during games against the Seattle Mariners on June 15 and the St. Louis Cardinals on June 27 6.
Betting integrity firm IC360 issued an alert after detecting unusual gambling patterns on these pitches. The alert specifically referenced action on Ortiz's first pitches to be either a ball or a hit batsman. In both instances, the bottom of the second inning against the Mariners and the top of the third inning against the Cardinals, when Ortiz threw first-pitch sliders that weren't close to strikes.
The investigation revealed that unusual amounts of money were wagered on these specific pitches from betting accounts across multiple states, including Ohio, New York, and New Jersey. These wagers, often referred to as microbets, allowed gamblers to bet on the outcome of individual pitches rather than broader game results.
For Clase, the connection to the betting investigation remains less clear, although reports indicate his involvement also relates to pitches that received abnormal betting action. According to one source, an unusual amount of money was placed on Clase to either throw a ball or hit a batter, as well.
MLB and OCCC coordinate on integrity probe
The investigation involves coordinated efforts between Major League Baseball and Ohio's gambling regulators. The Ohio Casino Control Commission confirmed it was notified on June 30 by an Ohio licensed sportsbook about suspicious wagering activity involving Guardians games. MLB promptly contacted the commission afterward regarding these concerns.
"Under the Commission's statutory responsibilities, an independent investigation commenced," the OCCC stated, noting that it has undertaken similar actions in past betting investigations. "The Commission is working closely with Major League Baseball's highly skilled investigative team as contemplated by Ohio law".
The case has potentially severe implications beyond baseball suspensions. If the investigation confirms wrongdoing, the players could face lifetime bans from baseball. This assessment stems from MLB's historical stance on gambling violations and the precedent set last year when San Diego Padres infielder Tucupita Marcano received a lifetime ban for placing nearly 400 baseball bets.
MLB Commissioner Rob Manfred has expressed concern about microbets, stating during the All-Star break that "certain types of bets strike me as unnecessary and particularly vulnerable, things where it's one single act, doesn't affect the outcome necessarily".
What are prop bets and why are they controversial?
Prop betting, a growing segment of the sports gambling industry, has moved to the center of integrity debates across professional sports. Understanding the nature of these specialized wagers helps explain why they've become a focal point for regulatory action.
Definition of prop and microbets
Proposition bets, commonly called "prop bets," differ fundamentally from traditional sports wagers. Unlike standard bets on game outcomes or point spreads, prop bets focus on specific events within games that often have little connection to the final result. They allow gamblers to wager on isolated aspects of player performance or game occurrences rather than overall team success.
Microbetting represents an even more specialized form of prop betting. These wagers focus on immediate, small-scale events—such as the outcome of the next pitch in baseball, the next point in tennis, or a specific shot in basketball 16. The results are typically determined within seconds, creating a rapid-fire betting experience.
Examples of high-risk prop bets
The sports betting marketplace offers numerous prop betting options that create particularly vulnerable scenarios:
Player performance props: Wagers on how many touchdowns a quarterback might throw, rebounds a basketball player might grab, or hits a baseball player might record
Pitch-by-pitch microbets: Betting on whether a specific pitch will be a ball, strike, or hit batter—precisely the type implicated in the Guardians investigation
First occurrence props: Wagers on who will score the first basket, touchdown, or goal in a game
Statistical thresholds: Betting on whether players will go over or under predetermined statistical benchmarks
These markets have gained substantial popularity, with some sportsbooks reporting prop bets could soon constitute up to half of all wagers placed.
Why individual player bets raise integrity concerns
The fundamental problem with prop betting stems from its susceptibility to manipulation. Primarily, individual players can control specific outcomes without necessarily affecting game results. This creates situations where influenced players can alter their performance to "game" betting markets.
The NBA's lifetime ban of Jontay Porter exemplifies this vulnerability. Porter allegedly made deals with gamblers to ensure he wouldn't reach statistical thresholds by faking injuries. Likewise, investigations into MLB players raise similar concerns about pitch manipulation.
Moreover, research indicates prop betting attracts problem gamblers. A Australian study i 2018 found that 78% of micro event bettors met criteria for problem gambling, compared to just 29% of those who didn't engage in such betting. The rapid, continuous nature of these wagers enables impulsive betting behaviors typical of gambling addiction.
Professional athletes face additional pressure through harassment from bettors. NBA player Michael Porter Jr. noted, "We really do get death threats" from gamblers angry about prop bet outcomes. Essentially, athletes become targets regardless of performance, disappointing someone who bet either the over or under.
OCCC reviews betting menu and prepares draft rule
The Ohio Casino Control Commission has begun evaluating Governor DeWine's request to eliminate proposition betting, marking another chapter in the state's evolving approach to gambling regulation. Following the MLB investigation announcement, regulators must now determine which wagers should remain available to Ohio bettors.
The OCCC confirmed it is "gathering information" on the request to remove prop betting from the state's sports betting market. "The Commission will announce its next steps in the upcoming days," stated Assistant General Counsel Emily Berner. Executive Director Matt Schuler has initiated a comprehensive review of microbets currently offered across all sports i preparation of drafting rules to remove certain player-specific props from the list of approved wagers for Ohioans.
The commission's approach appears targeted rather than comprehensive. Schuler clarified that DeWine's request primarily focuses on "in-game, player-specific microbets" rather than all player prop bets. This nuanced distinction suggests regulators may seek to eliminate only the most manipulation-prone betting markets.
Timeline for potential legislative approval
Any proposed rule would require approval from both the OCCC and the Ohio legislature before implementation. This multi-stage process typically involves filing governing rules with the state's Common Sense Initiative and the Joint Committee on Agency Rule Review, as well as consideration at public Commission meetings.
The commission generally requires at least 60 days from complete submission to review and approve compliance documents 4. Consequently, even under expedited conditions, new restrictions would likely not take effect until fall 2025 at the earliest.
Past precedent: college player prop ban in 2024
The OCCC has already demonstrated willingness to restrict prop betting. In February 2024, the commission banned all prop bets on individual collegiate athletes' performances. This prohibition came after NCAA President Charlie Baker requested the change and received support from Governor DeWine.
Data showed college player props constituted only 1.35% of Ohio sports betting wagers in 2023, totaling approximately $104.6 million of the $7.65 billion wagered statewide. Despite objections from eight of the state's 14 sports betting operators, Schuler determined the ban would "safeguard the integrity of sports gaming and will be in the best interest of the public".
Industry pushes back against proposed restrictions
Gambling industry representatives have mounted a coordinated response against Ohio's proposed prop betting ban, arguing that prohibition could create more problems than it solves.
American Gaming Association warns of unintended consequences
The American Gaming Association (AGA) has firmly opposed DeWine's request, stating that "eliminating proposition bets from Ohio's legal, regulated market does not address the root cause of recent integrity concerns, it only risks driving this activity into the shadows of the illegal market where no one is watching". Joe Maloney, AGA's Senior VP of Strategic Communications, emphasized that "prohibition doesn't stop betting - it stops oversight".
Sportsbooks argue for education over prohibition
Betting operators advocate for alternative approaches to address integrity concerns. Industry representatives suggest "education and deterrence" as the most effective strategy, focusing on ensuring athletes understand rules and recognize consequences 26. The AGA argues that the regulated market successfully works to detect potential misconduct, as demonstrated by the Guardians case where suspicious activity was flagged by legal operators working with leagues.
Furthermore, significant political resistance has emerged. House Finance Chair Brian Stewart vowed to "do all he could to stop DeWine from blocking prop bets," arguing the system works as designed since investigators identified the alleged cheating.
Comparison to international betting markets
Conversely, some offshore sportsbooks already limit proposition markets that Ohio seeks to ban. Adam Burns from industry giant BetOnline.ag noted they don't offer betting on first pitches because "it's too dangerous to offer pregame and even more dangerous live".
Nevertheless, industry advocates maintain that prohibition merely drives bettors to unregulated alternatives. Bill Pascrell III, representing gambling companies, cited previous cases where banned college bets simply shifted to offshore internet sites or prompted gamblers to travel to states where these prop bets are available.
Conclusion
The unfolding scandal surrounding MLB players and proposition betting demonstrates the complex challenges facing Ohio's sports gambling landscape. Governor DeWine's push for emergency restrictions specifically targets microbets that focus on individual player actions—precisely the type of wagers implicated in the Guardians investigation. Though the proposed ban builds upon Ohio's previous prohibition of collegiate prop bets, this expansion would significantly reshape the state's betting market.
Consequently, any regulatory changes must navigate competing priorities. MLB officials and state regulators rightfully emphasize protecting game integrity and preventing scenarios where individual players can manipulate specific outcomes without affecting game results. Yet, industry representatives raise valid counterpoints about driving bettors toward offshore operators. Their argument that education and deterrence might prove more effective than outright prohibition merits consideration as part of a comprehensive approach to gambling oversight.
Ultimately, Ohio's response to this scandal will likely establish precedent for other states grappling with similar integrity issues. The OCCC faces difficult decisions balancing consumer protection, sports integrity, and market viability. Additionally, their resolution must address the fundamental question at the heart of this controversy: whether certain types of proposition bets inherently create too much vulnerability to manipulation, regardless of safeguards.
The outcome will shape not just Ohio's betting landscape but potentially influence how American sports leagues and regulators nationwide approach the increasingly complex relationship between professional athletics and legalized gambling. Until then, both the Guardians organization and Ohio bettors await clarity on which wagering options will remain available as this regulatory drama unfolds.
