Diamondbacks' Dominican prospect is a scam victim, per detailed report

Belfi Rivera, a promising young player in the Arizona Diamondbacks’ Dominican Summer League roster, has been ensnared in a troubling financial exploitation case that sheds light on the vulnerabilities of aspiring baseball talent in the Dominican Republic.

Investigative reporting published by azcentral.com reveals that Rivera, just 14 years old when first approached, was targeted by Santo Caraballo, a figure infamous for predatory lending practices within Dominican baseball circles. Caraballo managed to obtain nearly $950,000 of the $1.8 million that the Diamondbacks committed to paying Rivera once he reached the age of 16.

The arrangement between Rivera and the Diamondbacks, like many similar deals in the Dominican Republic, was conducted verbally, leaving little to no official documentation. This informal contracting environment poses significant risks, with young players and their families often left vulnerable to financial manipulation and broken promises.

Caraballo’s scheme exploited Rivera’s family’s limited financial literacy and precarious economic situation, offering loans with exorbitant interest rates under the guise of support. To lend credibility to his operations, Caraballo purported an association with Hall of Famer David Ortiz, claiming Ortiz as a business partner. Ortiz has publicly denied any ongoing association, stating he severed ties with Caraballo over a year and a half ago. Nonetheless, footage surfaced showing Ortiz and Caraballo together as recently as September 2025, attending a high-profile concert in Puerto Rico, raising questions about the extent of their relationship.

Beyond Caraballo’s involvement, Rivera’s personal trainer, John Carmona, received a substantial commission of 35 percent—approximately $630,000—further depleting the funds intended for Rivera’s development. As a result, the young prospect was left with a fraction of the financial resources promised, despite the significant revenue generated through these side agreements.

Major League Baseball invests considerable resources in scouting and signing talent from the Dominican Republic, recognizing the country as a primary source of international players. The allure of transforming poverty into prosperity through baseball dreams is a narrative actively promoted by teams and agents alike. However, cases like Rivera’s reveal the darker side of this pursuit, where exploitation can overshadow opportunity.

The broader implications extend beyond Rivera’s individual story, illustrating systemic challenges within the recruitment and financial support infrastructures for Dominican prospects. The reliance on informal, verbal agreements and the presence of intermediaries who capitalize on families’ lack of financial knowledge create conditions ripe for abuse.

While MLB continues to scout aggressively in the region, the mechanisms to protect young players and their families from exploitative practices remain insufficiently robust. Rivera’s case underscores the urgent need for transparent contracts, financial education, and oversight to ensure that players receive the full benefits of their signed agreements.

Details about any ongoing investigations or potential reforms following the exposure of Caraballo’s activities remain limited. Nonetheless, the revelations about Rivera’s experience provide a critical lens through which to examine the intersection of sport, poverty, and predation in the Dominican baseball pipeline.

As Rivera’s journey unfolds, his story serves as a cautionary tale about the hidden costs behind the dreams of countless young athletes striving for a place in professional baseball. It also calls attention to the responsibility of organizations and authorities to safeguard the futures of these prospects beyond the playing field.
