Someone help me understand something about baseball.
So, as I understand it, it's a strike when they don't strike the ball, unless it's a ball. but if they strike the ball, it's not a strike nor a ball, unless it's foul, then it might or might not be a strike.

I'm incapable of separating a joke from a sincere question. I'll try to explain in case you're serious.

If the batter swings and makes no contact with the ball it's a strike. Swing and a miss. Did the batter make a complete swing? Ump call.

If the pitch doesn't go over the plate and is thrown between the batter's knees and chest (the strike zone) that is a ball by judgement of the umpire, as long as the batter didn't swing ( see above.) Only 4 ball are permitted per batter.

@BikeCurmudgeon
so I'm confused about the complete swing, I thought there was something called a "blunt" where they deploy the bat slowly? Is that part of an incomplete swing?

@MrsMouse
The "incomplete" swing comes from the 0.02 seconds (200 milliseconds) the batter has to make the decision to swing and where. They start to swing and the ball movement tells them to "stop" their swing mid-process.

Not easily done.
