What was the farthest Ash ever got in a Pokemon League, in the anime?

Question

I`m blatantly just curious on how far he actually got.

Pretty sure he's beaten the Elite Four before, in Hoenn I think

I need to know how far he went in a pokemon league

---

He won and he was offered to be a frontoer brain

---

I meant in a pokemon league with 8 official gyms, not the battle frontier.

---

He's got all 8 badges I believe

---

I want to know how far he`s gotten in total, of all of the pokemon leagues he has entered, disregarding the battle frontier and orange island league, since I know he`s never won, but I want to know out of curiosity how far he`s even gone, such as top 8, top 4, y`know, the works.

I'm pretty sure in Sinnoh in Diamond and Pearl series.
