Nope he lost. But honestly that's to be expected. It's been 20 years now. The animators have said that if Ash wins then the journey would be over because he's the strongest.
That makes zero sense and I guess that's more of a Japanese mindset. You can still win and continue on the journey. Anyway, don't expect Ash to ever win until they stop making games. Which will be never
Like I don't know if you guys play the games, but in an earlier match Ashs Greninja tanked 2 frenzy plant attacks from a mega sceptile. In the final, it got KO'd by a mega Charisse's using a fire attack. Think about that for a second. A water type can take 2 of the strongest grass moves, but gets KOd by a string fire attack
