Shohei Ohtani Gambling Scandal: Bookmaker Mathew Bowyer Reveals New Details on Ippei Mizuhara’s $17M Theft

Los Angeles Dodgers star Shohei Ohtani’s former interpreter, Ippei Mizuhara, engaged in illegal gambling, according to statements from his former bookmaker, Mathew Bowyer, during an interview with ESPN’s 30 for 30 podcast. The multi-million dollar theft and betting scandal, which resulted in stealing millions from Ohtani’s bank account, has renewed focus.

Mathew Bowyer Details the Scale of Mizuhara’s Gambling Habit

According to Bowyer’s interview remarks released through ESPN, Mizuhara’s compulsion was constant.

Federal court documents previously revealed that Mizuhara stole millions from Ohtani’s accounts to cover mounting sports betting losses.

Federal Investigation and Legal Consequences

Investigators confirmed through bank records, text messages, and audio recordings that Ohtani was entirely unaware of the illegal betting activity and cooperated fully with federal authorities, clearing the designated hitter and pitcher of any wrongdoing.

Mizuhara pleaded guilty in federal court to bank fraud and subscribing to a false tax return. Court filings showed that the wagers involved thousands of bets placed over a multi-year period, with Bowyer functioning as the primary illegal bookmaker operating in Southern California before federal law enforcement intervened.

Impact on Major League Baseball and the Dodgers

The scandal cast a massive shadow over the Dodgers’ championship run, forcing Major League Baseball to conduct its own internal review alongside the federal probe. Commissioner Rob Manfred’s office ultimately cleared Ohtani, establishing that the player was a victim of financial theft rather than a participant in prohibited baseball or sports wagering.

For Ohtani, the resolution of the legal proceedings allowed him to focus entirely on his historic 2024 campaign, where he became the first player in MLB history to achieve 50 home runs and 50 stolen bases in a single season, eventually culminating in a World Series title.

Next Steps in the Legal and Disciplinary Process

Mizuhara faces a lengthy federal prison sentence following his guilty plea, with sentencing hearings scheduled in federal court. Major League Baseball continues its ongoing monitoring of clubhouse compliance regarding gambling policies.
