Could be. With Ohtani, I would be floored if anyone in gambling was hearing anything, however. This is arguably the most secretive FA recruitment we've ever seen, especially in social media world.
My guess is that he got lucky on Judge and this isn't the only time he had jumped at something hours before, but misses 95% of the time. That's usually what these accounts do. Incarcerated Bob was another one of these accounts. With that said, he did surprise me when I saw the tweet wasn't a photoshop job, so I'll give him that. Perhaps CJ is just on it. But I think it'll likely be "in spite of" as opposed to "he knew" even if we sign him. But it's fun to think he's got a line here.
