Prosecutors Narrow Emmanuel Clase Betting Case to 18 Pitches
Federal prosecutors have narrowed the evidence they intend to present against former Cleveland Guardians closer Emmanuel Clase in an alleged sports betting conspiracy, identifying 18 pitches across 17 games as the focus of the upcoming trial.
The development gives the defense a clearer picture of the government's case ahead of jury selection, which is scheduled to begin on 2 November in the U.S. District Court for the Eastern District of New York.
Clase and fellow Guardians pitcher Luis Ortiz face federal charges connected to an alleged scheme involving advance information about specific pitches and wagers placed on their outcomes.
According to a 18 September government filing cited by iGaming Business, prosecutors will focus on 18 pitches thrown by Clase between May 2023 and May 2025. They also intend to present evidence concerning two pitches allegedly involving Ortiz.
Emmanuel Clase betting case narrows to 18 pitches
The government's latest filing represents a narrower evidentiary focus than earlier allegations.
Attorneys for Ortiz had previously stated that prosecutors had identified suspicious activity involving Clase in at least 48 games. The prosecution's current list covers 17 games and 18 specific pitches.
The pitches span multiple MLB seasons and include mostly regular-season appearances. One of the identified pitches came during the 2024 American League Division Series, when Clase faced Detroit Tigers outfielder Matt Vierling on 5 October 2024.
According to the prosecution's account, Clase's first pitch to Vierling was a 93-mph slider that missed the strike zone. Cleveland went on to win the game 7-0. The pitch is among the specific instances prosecutors plan to use at trial.
The list begins with a May 2023 game against the New York Mets and extends to May 2025.
IowaGamingBusiness reported that 17 of the 18 pitches identified by prosecutors involved a first pitch that was recorded as a ball, with the remaining pitch involving a later delivery in an at-bat.
Prosecutors allege advance information was shared with bettors
The central allegation is not simply that individual pitches produced particular betting outcomes.
Federal prosecutors allege that Clase provided advance, non-public information about pitches to bettors, allowing wagers to be placed with knowledge of the intended pitch characteristics or outcome.
The original federal indictment alleged that Clase and bettors coordinated around proposition wagers involving factors such as pitch type and velocity. Prosecutors said the information was sometimes communicated before or during games.
The Department of Justice previously alleged that bettors placed hundreds of wagers based on information supplied by the players and that the scheme generated at least $400,000 in fraudulent winnings from pitches allegedly rigged by Clase. A later superseding indictment cited by court records put the combined winnings attributed to bets involving Clase and Ortiz at at least $450,000.
The defendants have pleaded not guilty.
Luis Ortiz also faces allegations
The case extends beyond Clase.
Ortiz, a starting pitcher who joined the Guardians before the 2025 season, is accused of participating in the alleged scheme involving two pitches. Prosecutors have said they will seek to establish that advance information about those pitches was provided to bettors.
The Justice Department's original case alleged that Ortiz agreed to throw particular pitches as balls in exchange for payments. Prosecutors alleged that one arrangement involved a $5,000 payment to Ortiz and another $5,000 payment to Clase, while a second arrangement involved $7,000 payments to each player.
Both players were placed on non-disciplinary leave during MLB's investigation into sports betting. MLB announced in March 2026 that their leave would continue without pay while the legal proceedings moved forward. The league said the arrangement was not an admission of wrongdoing.
Micro-betting puts pitch-level integrity under scrutiny
The case highlights a specific integrity challenge associated with increasingly granular sports betting markets.
Traditional wagers can focus on game or player outcomes, while micro-betting allows customers to wager on individual events occurring within a contest. In baseball, that can include individual pitches and characteristics such as pitch type, location or velocity.
The allegations against Clase center on precisely this level of information.
Prosecutors say the alleged participants exploited advance knowledge of individual pitches to create an advantage for bettors. The original indictment alleged that some wagers involved thousands of dollars and that bettors used information about future pitches to place bets through online sportsbooks.
For sports betting operators, integrity monitoring of such markets can therefore involve activity occurring at a much more granular level than the final score or conventional player statistics.
The allegations remain unproven, but the case illustrates why access to non-public information can be particularly significant when betting markets are built around individual in-game events.
Prosecutors point to alleged coded communications
The prosecution is also expected to present evidence concerning communications between alleged participants.
According to the latest reporting on the government filing, prosecutors contend that code words were used when discussing alleged rigged pitches. One example involves the word “rooster,” which prosecutors say was used to identify a batter in communications connected to an alleged pitch-rigging arrangement.
The defense has disputed the government's interpretation of the term and has indicated that Clase's background and interest in rooster fighting in the Dominican Republic may be relevant to understanding the communications.
The dispute illustrates an issue that will ultimately be tested through evidence and arguments at trial rather than through the government's allegations alone.
November trial to test the government's evidence
The narrowing of the case to 18 Clase pitches gives the upcoming trial a more defined evidentiary framework.
The government's case is being prosecuted in the Eastern District of New York. The original indictment charged Clase and Ortiz with conspiracy offenses involving wire fraud, honest services wire fraud, sports bribery and money laundering.
A federal judge rejected motions seeking dismissal of the wire-fraud conspiracy count in September, allowing the case to proceed toward trial.
Jury selection is scheduled for 2 November.
The defendants remain presumed innocent unless and until proven guilty in court.
What the case means for sports betting integrity
The Emmanuel Clase betting case is being closely watched because it combines professional sports, athlete access to non-public information and highly granular betting markets.
The government's decision to identify 18 specific pitches provides a more concentrated picture of the evidence it intends to use. It also places individual pitch markets at the center of a major U.S. sports betting prosecution.
For the wider betting industry, the case demonstrates the importance of monitoring unusual activity around micro-bets, particularly where a participant may have access to information unavailable to the broader betting market.
The November proceedings will determine how prosecutors' allegations withstand scrutiny in court.
