Lol, exactly.
I think the first explanation given is probably correct in that his interpreter ended up with debts and told Ohtani who, because he's a nice guy, said he would help him out and sent some money to cover some losses, not realizing what a potential shitstorm it could end up causing him.
I still allow for the possibility that Ohtani is a gambler, but it doesn't seem like that's the case. If it was, ALL the wire transfers would have his name on them instead of 2.
The theft thing is a weak cover though, there's more holes in that theory than a deanmike post about anything related to baseball.
