It's a little confusing but in that situation they just left the Yes/No score first inning up and it just got more expensive once Houston went down top of first. I honestly don't know if that's how they do it every time but I printed the ticket.
You can tell by price. When is no first inning -298? That's a half inning price depending on pitcher.
Just wanted to clarify why it didn't name team to score that 1/2 inning.
May the odds be ever in your favor.
