What to Know About Sports Betting and Problem Gambling Amid Ohtani Scrutiny

The firing of Los Angeles Dodgers star Shohei Ohtani’s interpreter and close friend after allegations of illegal gambling and theft from the Japanese baseball player is shining renewed attention on compulsive gambling.

The team fired interpreter Ippei Mizuhara, who has been Ohtani’s constant companion since the star came to the U.S in 2017, on Wednesday after reports about his alleged ties to an illegal bookmaker and debts well over $1 million.

The law firm representing Ohtani said in a statement that he had been the victim of “massive theft.”

Mizuhara told ESPN this week that Ohtani knew nothing of his illegal wagers on international soccer, the NBA, the NFL and college Football. Mizuhara said Ohtani was an innocent victim of his friend’s gambling addiction.

What is problem gambling?

The National Council on Problem Gambling defines gambling addiction as “gambling behavior that is damaging to a person or their family, often disrupting their daily life and career.”

Gambling addiction is a recognized mental Health diagnosis, and the group says anyone who gambles can be at risk for developing a problem.

Its symptoms include thinking about gambling all the time; feeling the need to bet more money more often; going back to try to win money back, known as “chasing losses;" feeling out of control; and continuing to gamble despite negative consequences.

How widespread is it?

The council says about 2.5 million adults in the U.S. meet the criteria of having a severe gambling problem. Another 5 million to 8 million people are considered to have mild or moderate gambling problems.

The 800-GAMBLER hotline can offer help and referrals, and Gamblers Anonymous also has resources and support for those with a gambling problem.

What are sports leagues doing about gambling?

Baseball’s collective bargaining agreement includes an annual spring training education program for players on safety and security, including issues relating to sports betting and gambling.

This comes at the same time that the leagues—who bitterly fought against legalizing sports betting beyond the four states that allowed in before 2018—have become business partners with the biggest gambling outlets. Many teams and league have official sports betting partners and allow gambling company advertising on their premises. A few have even opened sports books at their stadiums.
