Of course, we know about the famous Ireland-Bulgaria game, but is there any other game where catching the Snitch was not enough for victory?
Yes, there was.
When the Gryffindor team was getting thoroughly beat by Hufflepuff due to Harry being banned from the team, Ginny caught the Snitch but Gryffindor still lost by ten points.
“The miracle was that Gryffindor only lost by ten points: Ginny managed to snatch the Snitch from right under Hufflepuff Seeker Summerby’s nose, so that the final score was two hundred and forty versus two hundred and thirty.”
