Which best explains the "sickly silence" that falls on the Mudville fans in the first stanza

Their team is very close to losing the game

The outlook wasn't brilliant for the Mudville nine that day; The score stood four to two with but one inning more to play. And then when Cooney died at first, and Barrows did the same, A sickly silence fell upon the patrons of the game. The poem's first four lines also set the scene for us. They give us the game situation in a pretty clear, entertaining way. For the home team, the "Mudville nine," things are not looking too good: "The outlook wasn't brilliant."
