Kasumi-san said:Okay my memory slipped there. She was third place. Still better than anything Ash did in that cup. And as for winning the Princess Tournament with pokémon that weren't hers to begin with just make her more of a skilled trainer: being able to handle pokes that she never trained before.
...Simply shouting 'Pikachu, Thunderbolt!' and 'Bulbasaur, Razor Leaf!' doesn't make her a skilled trainer at all. :3 If she was that good, she should have used all her Water Pokemon. The fact that she choose to use Ash and Brock's goes against what she believes... that Water Pokemon are the best.
