As in Pete Rose banned? I voted no based on what is known so far. His interpreter, Mizuhara, gave an interview to ESPN saying Ohtani paid off his gambling debts. Then he recanted that story when Ohtani and his lawyers said that he never tried to cover the gambling losses.
But there are 2 500K transfers from Ohtani to the bookie, in Ohtani's name. Also, why would a bookie extend hundreds of thousands of dollars of credit to someone like Mizuhara without knowing he was good for it.
I think Manfred will look the other way if the story holds its current course. A wealthy person helped out a friend in need with a Million Dollars. That's what friends do.
The stickler is how did the other $3.5 Million get to the bookie.
