The bookie for Ippei Mizuhara, who admitted to stealing nearly $17 million from Shohei Ohtani, told ESPN that the former Dodgers interpreter showed gambling problems within 30 days of betting.

"He was absolutely bananas," Mathew Bowyer said in a new episode of "The Betrayal of Shohei Ohtani". E. Martín Estrada, former U.S. Attorney, told ESPN he was not convinced Mizuhara’s actions could be explained solely by a gambling addiction.

Mizuhara pleaded guilty to bank fraud and filing a false tax return and is serving a 57‑month prison sentence at a low‑security federal prison in central Pennsylvania. He will be eligible for parole in 2029. Bowyer, who ran an illegal gambling operation, served seven months of a yearlong sentence and was released in May. Nevada casinos agreed to pay about $34 million in fines after an investigation found they failed to prevent Bowyer from laundering millions, including Ohtani’s money.

The Nevada Gaming Commission permanently banned Bowyer and listed him in the state’s "black book." Multiple casino licensees, including The Venetian, Caesars Palace, and MGM Resorts International, paid fines ranging from $7.2 million to $10.5 million for failing to verify Bowyer’s source of income and for allowing illegal bookmaking activity.
