I would argue that softball (and baseball) is not actually a team game and that one player could indeed lose you a game. I do agree that I would never call someone out on having a bad game. I would be more concerned with what I could have done (or do) to make that player more successful the next time they are in that situation.
Of course this is true, every player has suffered thru the experience. As a competitor
they know the mistake, they NEVER need to be reminded. Softball is a faster game
than BB, I never compare them
