MLB pitchers Emmanuel Clase and Luis Ortiz have been indicted on charges they took bribes from sports bettors to throw certain types of pitches, including tossing balls in the dirt instead of strikes, to ensure successful bets.

According to the indictment unsealed Sunday in federal court in Brooklyn, the highly-paid hurlers took several thousand dollars in payoffs to help two unnamed gamblers from their native Dominican Republic win at least $460,000 on in-game prop bets on the speed and outcome of certain pitches.

Clase, the Guardians’ former closer, and Ortiz, a starter, have been on non-disciplinary paid leave since July, when Major League Baseball started investigating what it said was unusually high in-game betting activity when they pitched. Some of the games in question were in April, May and June.

Ortiz, 26, was arrested Sunday by the FBI at Boston Logan International Airport. He is expected to appear in federal court in Boston on Monday. Clase, 27, was not in custody, officials said.

Ortiz and Clase “betrayed America’s pastime,” U.S. Attorney Joseph Nocella Jr. said. “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.”

Ortiz’s lawyer, Chris Georgalis, said in a statement that his client was innocent and “has never, and would never, improperly influence a game — not for anyone and not for anything.”

Georgalis said Ortiz’s defense team had previously documented for prosecutors that the payments and money transfers between him and individuals in the Dominican Republic were for lawful activities.

“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,” Georgalis said.
