Pokemon (2019) - episode 60 - 18 Mar, 2021

While resting at a Pokémon center, Ash's World Coronation Series rank has risen to 273. Ash and Goh come across Rinto, who is also participating in the World Coronation Series. It turns out that in the first encounter, Rinto was in the Normal Class, hence why Ash did not receive a notification. However, since Rinto is in the Great Class, both challengers can officially battle each other. Ash has a battle with Rinto and his Gallade and wins, defeating him with his newly evolved Sirfetch'd, and bringing his rank to 184. (Source: Wikipedia)
