To forfeit the game, was the last thing the team weary and exhausted wanted to do.
Explanation:
We use parentheses when we want to add extra information, a minor example or a brief explanation, sometimes it can be ommited if wished, as it might not be relevant, and the sentence has to make sense if the reader does not wish to read what is it in the parentheres; however, in this example you can see that what is actually in the parentheses is important, it is not extra information and if you try to read only what is no in parenthesis it'll be incomplete. Commas are used to make a little pause.
