The federal trial involving Cleveland Guardians pitchers Emmanuel Clase and Luis Ortiz is expected to feature testimony from several prominent MLB figures, including current players, team executives and league officials. Among the potential witnesses identified in court-related documents are Guardians general manager Mike Chernoff, assistant general manager Matt Forman, pitching coach Carl Willis and coach/interpreter Agustin Rivero, per The Athletic.

Current and former Cleveland catchers Austin Hedges, Mike Zunino and Bo Naylor have also been identified as potential witnesses. All three catchers were involved in receiving pitches that prosecutors allege were manipulated as part of the betting scheme. However, the actual witness lists remain under seal, and it is not yet established which individuals will ultimately testify.

Regardless, an MLB monitor had initially notified Matt Forman that Clase was using his cellphone in the clubhouse during a game, violating league policy. Forman subsequently reported the incident to MLB.

Quest Meeks, who leads MLB's policy, integrity and compliance division, is also among the identified potential witnesses. Meeks previously testified as a prosecution witness in the federal case involving former Los Angeles Dodgers player Yasiel Puig in January.

Paul Mifsud, MLB's head baseball operations counsel, is also listed. The government identified a total of 42 potential witnesses in proposed jury-selection questions, with the final list expected to be announced later.

The financial allegations are substantial. According to the prosecution, bettors involved in the arrangement generated more than $450,000 in profits through wagers connected to Clase's pitches.

The trial will determine whether Clase and Ortiz deliberately manipulated pitches to help bettors profit, or whether the alleged suspicious pitches were legitimate baseball strategy. With both pitchers pleading not guilty and MLB awaiting the outcome of its investigation, the case could have significant consequences for their careers.
