I'm going to register to buy any leftover tickets (which is doubtful), but I noticed this little caveat on the Reds webpage about details
Major League Baseball game dates and times are determined in the sole discretion of the Office of the Commissioner Of Baseball and/or the Cincinnati Reds, as applicable, and may be subject to change. You may not resell any tickets purchased in connection with the drawing or use such tickets for promotional purposes. Registrations are non-transferable with no cash redemptions or substitutions. All sales are final
Interesting little insert there. I wonder if I can sell the rights for someone to join me for the game?
