A Year After the Clase Gambling Scandal, Some MLB Players Still Question the League’s Betting-Integrity Safeguards

A year after federal prosecutors charged Cleveland Guardians pitchers Emmanuel Clase and Luis Ortiz in an alleged pitch-rigging scheme, MLB players remain divided on whether the league has done enough to protect the sport from gambling corruption. A recent player poll found that just over half of respondents believe MLB’s safeguards are sufficient, while roughly a quarter of players surveyed were unsure or felt uninformed, and the rest said the league’s response falls short.

Clase and Ortiz were indicted in November 2025 on charges including wire fraud conspiracy, honest services wire fraud conspiracy, conspiracy to influence sporting contests by bribery, and money laundering conspiracy. Prosecutors allege the pair manipulated the outcomes of individual pitches — including balls, strikes and velocity readings — to help bettors in the Dominican Republic collect roughly $460,000 in prop-bet winnings. Both pitchers have pleaded not guilty and remain on non-disciplinary, unpaid leave while the case heads to trial.

A Trial Delayed and a Widening Divide

The trial, originally set for May 2026, was pushed back six months by U.S. District Judge Kiyo Matsumoto to November, with jury selection now scheduled to begin November 2. The delay came as attorneys for Clase and Ortiz sparred over how to divide culpability. Ortiz’s legal team has argued their client was misled by Clase and played a far smaller role, noting prosecutors have tied Clase to roughly 250 pitches connected to the betting scheme compared to just two for Ortiz. The original indictment detailed nine specific pitches investigators say Clase rigged dating back to May 2023, with prosecutors indicating the number could grow as the investigation continues. Ortiz, by contrast, is accused of joining the alleged scheme far later, in June 2025.

The judge has yet to rule on requests from both sides to separate the cases into individual trials. Both players face a maximum of 20 years in prison on several of the counts if convicted, and both are subject to a lifetime ban from baseball under Rule 21 regardless of the criminal outcome. While out on bail, Clase has been permitted to travel to Arizona to train and stay close to his agent, though both pitchers remain barred from all baseball activities tied to their teams.

MLB’s Response: Micro-Betting Limits

One day after the indictment became public, MLB moved quickly with its sportsbook partners to curb pitch-level prop betting. Under the new policy, MLB Authorized Gaming Operators — which the league says covers more than 98% of the U.S. sports betting market — capped individual pitch-outcome wagers at $200 and barred those markets from being included in parlays. The restrictions specifically target so-called micro-bets, wagers tied to a single pitch’s velocity or classification as a ball or strike, which regulators and the league have identified as uniquely vulnerable to manipulation since they hinge on one player’s action rather than a broader game outcome.

Commissioner Rob Manfred later told reporters at owners meetings that the league does not currently anticipate further restrictions on prop bets, calling the changes “a really, really significant” step to reduce the incentive for manipulation. Manfred emphasized that betting-pattern monitoring remains the backbone of MLB’s integrity efforts, telling reporters the ability to “discern inappropriate patterns is really, really important” and that the league had understood the risks around prop bets “from the very beginning.” MLB has also said it would cooperate fully with a Senate inquiry into the scandal, though Manfred maintained the league is generally prepared to move forward under its existing rulebook.

Players Split on Whether Rule 21 Is Enough

Despite the new limits, the recent player survey shows the locker room isn’t fully convinced the league has closed the gap. Supporters of MLB’s current approach point to the clarity of the rule itself. “It’s the first rule: Rule 21,” one multi-time All-Star said. “No betting on baseball.” An AL catcher echoed that sentiment, saying players are told the rules directly but also have to police themselves: “We know the rules. But you have to monitor yourself as well.”

Teams reinforce the message every spring, with MLB presenting a rules briefing to every clubhouse and signage posted throughout training facilities. An NL Central hitter described the messaging as unambiguous: “They come in here and emphasize, ‘It’s black and white: bet on baseball, you’re finished.’ It’s a straightforward rule to follow.” A veteran NL starter added that the consequences are widely understood across the league. “Everyone understands it’s a lifetime ban,” he said.

Still, a meaningful share of players who responded to the poll said they either don’t feel adequately informed about the league’s safeguards or believe more needs to be done — a signal that a year after Clase’s arrest, MLB’s messaging hasn’t fully closed the trust gap it opened. Some players have noted privately that even with the education sessions and clubhouse postings, the sheer scale of legalized sports betting since 2018 — when MLB signed its first gambling partnership with MGM Resorts — has made the sport more exposed than the rulebook alone can address.

What Comes Next

With both pitchers’ trial now set for November and increased scrutiny on prop-bet markets across all major sportsbooks, MLB’s ability to demonstrate that its monitoring systems actually catch bad actors before games are compromised will likely shape how players — and fans — view the league’s sports betting partnerships going forward. The case also looms as a test of how leagues and operators police fast-growing micro-betting markets more broadly, an area regulators have flagged as an emerging integrity risk across multiple sports, not just baseball.
