ESPN carries an AP report on a professional gambler who threatened violence against professional athletes. He pleaded guilty to threatening four Tampa Bay Rays players after they lost a home game:

He had made numerous violent threats in 2019 against athletes and their family members through anonymous Instagram accounts, according to a criminal complaint. In many messages, Patz threatened to enter the athletes’ homes and behead them or their family members, the FBI said. Some of Patz’s threats also contained derogatory terms and racial slurs, investigators said.

The story does not spell it out, but I assume he lost money due to the outcome of the game.
