What would happen if Percy had a fight with Poseidon [pjo]?

Well, I honestly think that he'd give him a good fight but Poseidon would come out on top. Percy gave Hades a run for his money. Strike that. He defeated Hades, who was in his domain where he is the most powerful btw, and pinned him down. Yes, we're talking about Achilles Curse Percy. Let's say they fight in the ocean.

Percy has the homefield advantage but Poseidon has the "being the field" advantage. We're talking Poseidon with his trident here. That thing took down Typhon. Tell me what you guys think and don't tell me that this wouldn't happen in canon. We all know. It's a hypothetical situation.
