The Ohio Casino Control Commission (OCCC) is preparing to introduce new regulations that could ban certain micro-bets, with concerns rising over their potential to be exploited. This move comes amid an ongoing investigation involving Cleveland Guardians pitchers Emmanuel Clase and Luis Ortiz, focused on unusual betting activity linked to their performance.
The investigation, jointly conducted by Major League Baseball (MLB) and the OCCC, arose after a sports betting monitoring firm, IC360, detected a significant increase in small bets placed on Ortiz’s first pitches during games on June 15 against the Seattle Mariners and June 27 versus the St. Louis Cardinals.
Details of the Betting Investigation and Player Leaves
Ortiz’s pitches, which led to bets on whether they would be balls or hit-batsmen, were both balls, according to the monitoring firm’s analysis. This irregular betting pattern triggered administrative actions, with Ortiz being placed on paid leave beginning July 3, when he held a 4-9 win-loss record and a 4.36 ERA. His leave has since been extended to August 31. Emmanuel Clase remains the only other Cleveland Guardians player involved in the investigation and on leave.
This probe has drawn attention to the vulnerabilities of micro-betting, small wagers placed on specific, immediate events that can attract syndicates aiming to manipulate odds before placing large bets to secure disproportionate winnings.

Governor DeWine’s Response and Broader Sports Betting Concerns
Ohio Governor Mike DeWine has directed the OCCC to reform micro-betting rules to prevent exploitation and protect betting integrity. The governor also signaled plans to engage with unions from North America’s major sports leagues to address these risks collectively. MLB Commissioner Rob Manfred has acknowledged the problem and affirmed ongoing efforts to improve transparency and monitoring.
“There are certain types of bets that strike me as unnecessary and particularly vulnerable,” Manfred had said.
“…I firmly believe that the transparency and monitoring that we have in place now, as a result of the legalization and the partnerships that we’ve made, puts us in a better position to protect baseball than we were in before,” he added.
Industry Reaction: American Gaming Association Raises Concerns Over Excessive Restrictions
The American Gaming Association (AGA), representing casino interests, expressed opposition to further restrictive oversight, suggesting that such measures could drive betting underground rather than eliminate problematic activity. They argue that education and deterrence offer more effective solutions than outright bans.
“Prohibition doesn’t stop betting-it stops oversight. Illegal operators won’t honor bans, won’t partner with leagues, and won’t protect players or fans. The most effective path forward is education and deterrence,” their statement read.
Despite the AGA’s warnings, sportsbooks nationwide appear willing to cooperate with regulators to safeguard the integrity of betting environments while adapting to new requirements.
Potential Impact and Next Steps in Ohio’s Betting Landscape
The actions taken by Ohio authorities in response to the Emmanuel Clase betting investigation Ohio highlight a growing concern about micro-betting’s risks in sports wagering. Restrictions on these bets could reshape how sports betting operates in the state and influence other jurisdictions watching closely. As the investigation progresses, it is likely that regulatory frameworks will evolve to balance the promotion of legal betting markets and the protection of sports integrity.
