We then go over to the seats/camera behind the first- or third-base field entrance and wait for the show. I write down everything on note cards, so I can rehearse and refer to it if I forget. I usually am still writing on the note cards because I’m just slow, and everyone else is talking in the office. Then I rehearse with the other in-game host about 10 minutes before we go live in stadium, usually on field or in the left- or right-field plaza. Once pregame ends, we usually go eat or just hang out in the office until our first in-game feature.
