Bunt Defense
Every fielder has a job the moment the batter squares.
How it actually works. In the standard coverage the corners charge on the pitch, the pitcher breaks off the mound, the first baseman's ground is the line and the third baseman's is everything in, the second baseman covers first and the shortstop covers second. The wheel play is the aggressive version with a runner on second: both corners charge hard, the shortstop rotates behind the runner to cover third, and the throw goes there. It turns a sacrifice into a force at third and a runner still at first.
Why it is done, and when it is wrong. Which coverage you call is a bet on the batter. Concede the out and you never lose the play but you always pay the base. Run the wheel and you can end the inning's threat entirely, but the shortstop has left the middle of the field and the runner at second can read the rotation and simply stay put, and if the hitter pulls the bat back and slaps it through the vacated hole you have given up a hit and a run. That counter, the slash, is precisely why the wheel is called sparingly and almost never against a hitter who can swing.
What people get wrong about it. The most common failure is not the coverage, it is the throw. A third baseman fielding a bunt on the run and throwing across his body to first is the highest error rate play a corner infielder makes, and a defense that charges hard without drilling the footwork loses more games to the throw than it saves with the aggression.
At Little League and travel ball. Most youth teams have exactly one bunt coverage and do not practice it. Any travel team that drills two coverages and a signal to switch between them has an advantage that shows up in every tournament weekend.
