Arizona would be foolish to trade for Ohtani. They aren't even a lock to make the postseason and they need a lot more than Ohtani to win it all.
Baltimore is interesting but I think they'd still need at least another starter.
Texas is getting a career year out of Eovaldi and they'd be upgrading maybe the worst DH platoon in baseball from Robbie Grossman and Brad Miller to Ohtani. They could put out Semian, Ohtani, Garcia, Seager and Jung as their first five bats.
Tampa still makes the most sense to me. They never have enough juice in their lineup to win in the postseason. Ohtani would give them that, plus a third monster arm in the starting rotation. The Rays are always pumping out prospects but they'll never sign a guy like Ohtani. A rental to go all-in for once with a team that's ready but missing one more piece. If they don't make a move for him (assuming Anaheim will trade Ohtani), I'll be incredibly disappointed in them. It would show that they are not a serious organization. Even the A's have pushed their chips in when they've been close, it just never worked out for them but you have to try.
