By complete chance, I already have tickets to this game. We bought tickets to it because it was fireworks night and we wanted to go to the stadium once this year, even if it’s a meaningless game and they suck.
EDIT: Ok, I got the full info. He is being activated on the 25th. He could play in any game from then to the end of the year. Like, he could pinch hit or something at the end of the final game or what not. That said, he has only been confirmed to start at 3B in one game. The game we are going to on the 29th with the fireworks. Bought the tickets like a month ago. What a coincidence.
