Concerns over the integrity of U.S. professional sports have intensified following the federal indictments of Cleveland Guardians pitchers Emmanuel Clase and Luis Ortiz, prompting a direct request for answers from members of Congress. Lawmakers from the Senate Committee on Commerce, Science and Transportation, which has oversight authority over major sports leagues, reached out to MLB Commissioner Rob Manfred with a letter outlining what they described as a “new integrity crisis” linked to the alleged betting scheme.

Lawmakers Seek Clarity on MLB’s Oversight Failures

The two pitchers were charged with coordinating pitch manipulation across several games so that gambling partners could profit, a development lawmakers said represents a far more serious breach than recent betting-related violations in baseball. According to federal prosecutors, the alleged misconduct began in May 2023 and continued undetected for two years. In the lawmakers’ view, the length of time before discovery raises fundamental questions about MLB’s oversight systems, especially when contrasted with other cases.

According to ESPN, Committee leaders Sen. Ted Cruz and Sen. Maria Cantwell pointed directly to MLB’s lifetime ban of former Pittsburgh Pirates infielder Tucupita Marcano as an example that underscores the gap in enforcement. Marcano was permanently removed from the league in 2024 after placing hundreds of bets on baseball games. The senators highlighted the apparent inconsistency in MLB’s monitoring capabilities, asking, “How did MLB catch Marcano and ban him for life but failed to notice Clase allegedly rigging pitches for two years?” They emphasized that, “The integrity of the game is paramount. MLB has every interest in ensuring baseball is free from influence and manipulation. … But in light of these recent developments, MLB must clearly demonstrate how it is meeting its responsibility to safeguard America’s pastime.”

The letter asks MLB to provide an explanation of when and how it became aware of suspicious betting and pitch-manipulation activity involving Clase and Ortiz. Lawmakers also requested documentation related to the league’s betting policies, internal investigative procedures and any investigation involving players, coaches, team employees, or owners since January 1, 2020. Senators set December 5 as the deadline for the league to submit the requested materials.

MLB has not yet issued a detailed public response. However, shortly after the indictments, the league announced that its sportsbook partners would implement a $200 cap on all wagers tied to individual pitches and remove pitch-level props from parlay eligibility. The stated aim is to reduce the financial incentive for manipulation by limiting potential payouts.

Concerns Extend Beyond Baseball as Gambling Scandals Spread

The Senate letter comes as multiple professional leagues confront their own integrity challenges. In a separate move this fall, the same committee contacted the NBA seeking clarification on how it is managing an unrelated series of alleged betting violations tied to figures within that league. The NBA has reportedly instructed several franchises, including the Los Angeles Lakers, to turn over materials such as documents and electronic devices. Those requests follow federal charges filed against former Portland Trail Blazers coach Chauncey Billups, former player and coach Damon Jones, and Miami Heat guard Terry Rozier in connection with another gambling investigation.

Lawmakers warned that these overlapping scandals across multiple leagues suggest that the problem may extend beyond isolated incidents. They wrote, “An isolated incident of game rigging might be dismissed as an aberration, but the emergence of manipulation across multiple leagues suggests a deeper, systemic vulnerability. These developments warrant thorough scrutiny by Congress before misconduct issues become more widespread.”

Meanwhile, both Clase and Ortiz appeared in federal court in New York last week. Each pleaded not guilty to the charges that they accepted bribes and manipulated pitches for gambling partners. Their cases continue to move forward through the judicial process.
