Two former college basketball players and an ex-sportsbook employee face felony charges stemming from an alleged prop bet fixing scheme, according to Nevada court documents.
Steven Vasquez, who played basketball for Fresno State and San Jose State, and Matthew J. Martin, who worked at DraftKings as a sports trader in Las Vegas, were arrested in September and charged with committing a fraudulent act in a gaming establishment and attempting or conspiring to cheat at a gambling game.
The Clark County District Attorney also issued an arrest warrant in August for former Fresno State player Mykell Robinson, who remains at large, according to a spokesperson for the DA's office. Robinson has been playing abroad professionally and could not be reached for comment.
Martin and Vasquez have pleaded not guilty to the charges, according to their attorneys. The charges are Class C felonies, carrying penalties of one to five years in prison and fines.
"Mr. Martin looks forward to proving his innocence in a court of law and doesn't intend to litigate the case in the press," attorney Crane Pomerantz told ESPN.
Vasquez's attorney declined comment.
The alleged scheme was centered on Robinson's statistics during a 2025 game between Fresno State and Colorado State, according to court documents and the NCAA. Robinson has been accused of manipulating his performance in the game, while Vasquez, Martin and another ex-DraftKings employee, Samuel Silverman, allegedly placed bets on the under on his statistics with a Las Vegas sportsbook.
Robinson played only 21 minutes against Colorado State, finishing with three points on one 3-pointer, two rebounds and no assists. Martin's bets won a net $15,950, according to records previously obtained by ESPN.
Vasquez and Robinson were roommates at Fresno State during the 2023-24 season, according to the NCAA. Vasquez transferred to San Jose State the following season, when the alleged scheme took place. The NCAA ruled Vasquez and Robinson ineligible after an investigation.
Silverman was the team manager for the Fresno State men's basketball team during the 2022-23 season, according to the school.
Silverman was arrested in May and faces similar charges related to the case. He pleaded not guilty and his attorney previously told ESPN he would "present a vigorous defense."
Silverman and Martin worked as sports traders at DraftKings' Las Vegas office in 2025, the company previously confirmed to ESPN. They did not have any responsibilities setting college basketball odds, according to a DraftKings spokesperson. DraftKings does not offer sports betting in Nevada but maintains an office in Las Vegas. ESPN has a business relationship with DraftKings.
When contacted by ESPN about the new arrests, a DraftKings spokesperson referred ESPN to its previous statement on the matter.
"The alleged activity at issue did not occur on DraftKings' platform, and the individuals involved are no longer employed by the company," the spokesperson told ESPN in July. "We strongly condemn the alleged conduct of these former employees and remain committed to protecting the integrity of sports and sports betting."
A spokesperson for the Nevada Gaming Control Board declined to discuss the case specifically when contacted by ESPN and said in a statement they "will continue to aggressively investigate any activity that threatens the fairness and public confidence of regulated sports wagering."
