Which detail from the section "The view from the Bleachers" BEST shows which team the narrator wants to win the game?

It shows that Perez believes it is a very important moment. Toward the end, he (assumed) uses the words "for our beloved Coyotes." Given that, one could say that Perez is a big fan of the Coyotes. He knows about baseball down to the smallest of details, and this moment was a "frozen in time" moment of importance because of the anticipation.

We're all waiting to see if Perez can strike out Branson so we could all go home happy
