Cleveland Guardians pitchers Emmanuel Clase and Luis Ortiz were charged with fraud, conspiracy and bribery stemming from an alleged scheme to rig individual pitches that led to gamblers winning hundreds of thousands of dollars, according to an indictment unsealed by federal prosecutors Sunday.
Ortiz, 26, was arrested Sunday morning in Boston and will appear in court Monday, according to prosecutors. Clase, 27, is not in custody.
Prosecutors at the Eastern District of New York, the Brooklyn-based United States Attorney’s office that levied similar charges against NBA player Terry Rozier and multiple coaches in late October, said in the indictment that Clase arranged with a bettor as early as May 2023 to throw specific pitches for balls so the gambler could place prop bets and profit. Ortiz, prosecutors said, joined the scheme in June 2025, and between the two, gamblers won at least $450,000 wagering on their pitches, while Clase and Ortiz were given kickbacks for their participation.
Clase and Ortiz each could face up to 20 years in prison for wire fraud conspiracy, 20 years for honest services wire fraud conspiracy, 20 years for money laundering conspiracy and five years for conspiracy to influence sporting events by bribery, according to prosecutors.
“The defendants deprived the Cleveland Guardians and Major League Baseball of their honest services,” Joseph Nocella Jr., the U.S. Attorney for the Eastern District, said in a statement. “They defrauded the online betting platforms where the bets were placed. And they betrayed America’s pastime. Integrity, honesty and fair play are part of the DNA of professional sports. When corruption infiltrates the sport, it brings disgrace not only to the participants but damages the public trust in an institution that is vital and dear to all of us.”
In a statement to ESPN, Ortiz’s attorney Chris Georgalis denied the charges, saying his client “has never, and would never, improperly influence a game — not for anyone and not for anything.” A message to Clase’s attorney seeking comment has not been returned.
Clase, a three-time All-Star and two-time Reliever of the Year, and Ortiz were placed on non-disciplinary paid leave by MLB in July after betting integrity firms flagged irregular wagering on a pair of pitches thrown by Ortiz in June.
While the pervasiveness of legalized gambling has upended the sports world, the allegations against Clase and Ortiz are the most severe for the sport since Pete Rose agreed to a lifetime ban for betting on baseball in 1989. MLB’s rules against gambling on the sport are strict, and Clase and Ortiz could face lifetime bans similar to the one delivered last year to San Diego Padres infielder Tucupita Marcano, who placed nearly 400 bets on baseball.
In a statement, MLB said: “MLB contacted federal law enforcement at the outset of its investigation and has fully cooperated throughout the process. We are aware of the indictment and today’s arrest, and our investigation is ongoing.” The Guardians in a statement said they were aware of the charges and will continue to cooperate with law enforcement and MLB.
In a 23-page indictment, prosecutors outlined a scheme perpetrated by Clase, the right-hander regarded as one of the best relief pitchers in baseball. According to prosecutors, Clase would regularly throw balls instead of strikes and sliders rather than cutters on the first pitch of at-bats in which bettors would wager on the individual pitches to be balls or under a specific mph threshold. The proposition bets, according to the indictment, would often be stacked in a parlay, leading to greater winnings.
Clase provided money to bettors to gamble on his behalf, texted with bettors during games and later was joined in the scheme by Ortiz, a right-hander who joined the Guardians in a December 2024 trade, the indictment said.
The earliest example, according to the indictment, came in a May 19, 2023, game between the Guardians and New York Mets, in which Clase relayed information that he would throw a pitch faster than 94.95 mph. Bettors, prosecutors said, won $27,000 on that pitch. Weeks later, bettors added a leg to a parlay for a pitch to be a ball slower than 94.95 mph — and won $38,000 when Clase spiked a slider at least 5 feet in front of home plate.
By April 2025, the indictment said, Clase “requested and received bribe and kickback payments in exchange for agreeing to throw specific pitches.” One day after throwing a pitch that hit the grass in front of home plate — about 10 feet short — Clase texted one bettor asking if he had gambled on the pitch, according to the indictment. When the bettor affirmed he had, the indictment said, Clase asked for money to be sent to the Dominican Republic — where Clase, Ortiz and the bettor are from — “for repairs at the country house.”
During the three years of the alleged scheme, prosecutors said, one bettor placed 16 parlays in which one leg was Clase throwing a ball. Of the eight pitches involved in those bets, seven were successful. The eighth was a pitch in the dirt swung at by Los Angeles Dodgers outfielder Andy Pages.
Ortiz’s involvement started June 15, 2025, according to the indictment, when he agreed with Clase that he would be paid $5,000 to throw the first pitch of the second inning for a ball. Clase, prosecutors said, received $5,000 for arranging the alleged fraud. Two bettors wagered a total of $13,000 on the pitch, the indictment said. When Ortiz received a payment of 90,000 Dominican pesos — approximately $1,400 — Clase directed him to lie about the purpose of the money if asked and say “this payment is for a horse,” according to prosecutors.
“Okay, perfect,” Ortiz said.
On June 27, 2025, Ortiz agreed to throw the first pitch of the third inning for a ball in exchange for $7,000, the indictment said. Bank security footage captured Clase withdrawing $50,000 in cash, of which he gave $15,000 to one of the bettors, who was in Cleveland that day, to wager on the pitch, according to prosecutors. The bettors placed $18,000 on the pitch, which was far outside the strike zone, according to the indictment.
Georgalis disputed the indictment’s findings in his statement.
“As Luis’ defense team extensively explained and documented to the government before these charges were brought, Luis’ payments and other transfers of money between him and individuals in the Dominican Republic were for lawful activities,” the statement read. “Notably, the indictment completely lacks any alleged evidence connecting Luis to these alleged bettors or demonstrating any purposeful involvement in a scheme.
“There is no credible evidence Luis knowingly did anything other than try to win games, with every pitch and in every inning. Luis looks forward to fighting these charges in court. The government’s case is weak and circumstantial. He will defend himself, and he will be prevail.”
Clase has made more than $12 million over a major league career that has spanned seven seasons, and he was scheduled to make $6.4 million in 2026. Ortiz’s salary in 2025 was $782,600.
