MLB and sportsbooks set a nationwide US$200 limit on pitch bets
MLB and US sportsbook operators have agreed to introduce a nationwide US$200 limit on bets placed on individual baseball pitches and to prohibit such wagers from inclusion in parlays, according to ESPN.
The measure intends to reduce the risk of manipulation following a recent pitch-rigging case involving two Cleveland Guardians players.
Unusual betting patterns were detected during June games involving pitcher Luis Ortiz, who, along with teammate Emmanuel Clase, was indicted on federal charges related to betting on specific pitches and pitch velocity. Prosecutors said the scheme generated approximately US$450,000 in winnings.
MLB Commissioner Rob Manfred said the betting restrictions demonstrate the league’s continued focus on integrity, stating, “I commend the industry for working with us to take action on a national solution to address the risks posed by these pitch-level markets, which are particularly vulnerable to integrity concerns.”
The agreement includes operators like Bally’s, BetMGM, Caesars, DraftKings, FanDuel, and Penn Entertainment.
Ohio Governor Mike DeWine, who earlier called for a ban on micro-proposition bets, welcomed the decision, adding, “By limiting the ability to place large wagers on micro-prop bets, Major League Baseball is taking affirmative steps to protect the integrity of the game and reduce the incentives to participate in improper betting schemes. I urge other sports leagues to follow Major League Baseball’s example with similar action.”
DraftKings and FanDuel confirmed they had updated their baseball betting offerings to comply. FanDuel President Christian Genetski added, “This initiative illustrates our unwavering commitment to building a legal and regulated market that roots out abuses by those who seek to undermine fair competition and damage the integrity of the games we love.”

The Backstory
How a micro-betting boom collided with a rigging scandal
The new nationwide cap on pitch-level bets grew out of converging trends: a surge in MLB micro-markets and a high-profile integrity case that cut to the core of in-game wagering. Beginning last year, operators expanded fast, granular bets on pitch outcomes, speeds and at-bat events, feeding demand for second-by-second action and driving engagement. That growth thrust risk controls into the spotlight after data monitors flagged irregularities tied to Cleveland Guardians games in June, prompting league and law enforcement scrutiny that has since reshaped how books handle baseball’s most volatile markets.
Federal prosecutors escalated the matter this summer with charges alleging a scheme to manipulate individual pitches for betting profits. Authorities said the effort generated hundreds of thousands of dollars in winnings, and they accused two Cleveland pitchers of conspiring with gamblers to influence micro-prop wagers. The case put pitch-by-pitch gambling—long marketed as an innovation—under integrity pressure almost overnight.
Against that backdrop, the league and leading operators coordinated a response that targets the most vulnerable slice of the product set. By capping wager size on pitch bets and barring those wagers from parlays, MLB and sportsbooks aim to reduce both the incentive to cheat and the leverage available to exploit inside information, a move that reinforces the industry’s balancing act between product innovation and game protection.
From suspicious wagers to federal charges
The first public signs of trouble surfaced when a betting integrity firm flagged unusual activity on pitches thrown in two Guardians games. League officials opened a probe, followed by law enforcement. Prosecutors later alleged that the plot began in May 2023 and involved inside information and, at times, deliberately thrown balls to tilt micro-prop outcomes. The indictment outlined wire fraud conspiracy, honest services fraud, sports bribery and money laundering counts, with potential prison terms of up to 20 years if convicted. Read more on the allegations in Two Major League Baseball players charged in pitch-fixing case.
The legal turn elevated risk concerns for a category of wagers designed for speed and volume. Pitch-level markets move quickly and can be influenced by a single participant’s action, creating a narrower set of variables than, say, full-game totals or multi-leg parlays. That makes aberrant patterns easier to spot but also potentially more rewarding—and damaging—if corrupted. The charges, naming two active players, underscored the integrity exposure for leagues and books as micro-betting proliferates.
Cleveland fallout and MLB’s paid-leave posture
As the investigation intensified, MLB and the MLB Players Association placed the two pitchers on paid, non-disciplinary leave. The league initially sidelined Luis Ortiz in early July, then moved to place All-Star closer Emmanuel Clase on leave later that month. The Guardians said they would not comment while inquiries were ongoing.
Coverage of the moves shows how the process unfolded in real time. The second leave and timeline details are outlined in Second Cleveland Guardians pitcher on leave for gambling investigation. MLB subsequently extended the leaves “until further notice,” as detailed in Guardians pitchers remain on indefinite leave amid MLB gambling probe. The league’s formal statement about non-disciplinary status and extensions also appears on its site; see MLB’s update on Clase’s paid leave.
The leave decisions signaled two priorities: insulate the competitive product while protecting due process. By keeping the players off the field without imposing discipline, MLB preserved the investigation’s integrity and avoided prejudging the legal case. The ongoing status also kept pressure on stakeholders to deliver systemic fixes rather than rely on one-off discipline.
Policy pressure builds in Ohio
The case also galvanized regulators. Ohio, home to the Guardians, moved quickly to aid MLB’s investigation and opened its own inquiry. State leaders pressed for tighter controls on micro-prop markets, arguing the wagers create outsized risks relative to their entertainment value. The governor publicly urged the state regulator to remove certain proposition bets and later called for broader limitations.
The state’s stance is captured in coverage of Ohio’s response and the commission’s separate probe, as well as the governor’s direct request to regulators in his statement urging removal of certain prop bets. The early, public push from Columbus added political momentum for leaguewide changes and helped set a template for multi-jurisdictional coordination—especially important in a patchwork U.S. market where state rules vary and integrity threats cross state lines.
By the time MLB and the major books agreed to the $200 cap and parlay exclusion, there was already a clear policy runway: data alerts from integrity monitors, enforcement action by prosecutors and explicit calls from state leadership. The result is a nationwide action that raises the floor for risk management instead of relying on uneven, state-by-state limits.
Innovation meets new guardrails at the books
Even as limits tighten on pitch props, sportsbooks continue to invest in MLB products that drive engagement. Providers have rolled out in-play bet builders and a wider array of player and game props, supported by real-time data feeds. Those initiatives aim to keep customers active during broadcasts with more personalized, combinable markets. A snapshot of that push appears in Altenar extends MLB coverage with new in-play features, which details expanded bet builders, fast markets and pitcher performance lines.
Operators are also layering gamified experiences onto traditional markets. Rush Street Interactive’s BetRivers, for example, launched MLB-themed PropPacks, a digital card mechanic that awards randomized bonuses tied to player milestones when bettors place qualifying same-game parlays. The product builds on a similar NBA rollout and arrives alongside a responsible gambling campaign tied to teen education. See MLB PropPacks added to BetRivers sportsbook for how the program works and its eligibility thresholds.
The new cap does not eliminate these offerings; rather, it narrows exposure where a single action can swing a bet. Books get to preserve breadth—same-game parlays, in-play builders, team and player props—while constraining the most easily manipulated wagers and removing them from parlay multipliers that can magnify illicit gains.
Stakes for fans, books and the league
The integrity stakes are straightforward: if a single pitch can be bought, fan trust can be sold. The alleged scheme tested whether rapid-fire markets could be protected when a participant has both motive and means to influence an outcome. The combined response—federal charges, paid leaves, state-level pressure and now uniform betting limits—shows the cost of getting it wrong and the framework for getting it right.
For fans, the cap may slightly dull the edge of ultra-specific wagers, but it attempts to restore confidence that what happens between the lines is authentic. For operators, it is a trade-off: keep the engagement engine humming while curbing a narrow category that poses outsize risk. And for MLB, the action creates precedent. Other leagues facing wagers on single-player events or micro-moments will likely study the impact as they weigh their own limits.
The timeline from flagged bets to federal court, and from state pressure to a national cap, illustrates both the fragility and adaptability of the modern betting ecosystem. Integrity incidents move faster in a micro-betting world. The guardrails now have to move just as fast.
