Swing and a Miss
The pitch comes in, the batter times it up, swings… and they completely miss. It happens. Actually, it happens a lot. Hitting a baseball is hard! Even if the batter swings at the exact right time, they still need to get their bat path to meet up with the ball. If that doesn't happen… welp.
The result is a swinging strike. There aren’t any special carveouts or caveats here1. On a swinging strike, the umpire may or may not make the same “strike” motion as they would with a called strike, simply because, well, when the batter swings and misses, it’s fairly apparent.
