I bought Reds tickets and now I can't go so does anyone know a way to sell them on StubHub?
They're just single game tickets but they're great seats on the third base line just above the dugout.
No idea then never tried it. I see the sell link right at the top of the main StubHub page. When I click that it asks to pick the event and I typed Cincinnati Reds. I choose a random Reds game from the list on the next page and from that point it asks me to login. I'm not going to create an account on a site I'll probably never use to test beyond that. If that doesn't work for you then maybe contact their customer support and ask.
Edit: Okay made this post before I saw your post about giving them away.
