How is catching a thrown ball interpreted for plays at the plate?

• A. The catcher must apply legal tags or make a play to record an out at home
• B. The runner is out automatically
• C. The ball becomes dead
• D. The pitcher is charged with an error

Answer: (A)

When a ball is thrown to the plate, an out at home is not automatic just because the ball is caught. The defense must actually tag the runner or touch him with the ball before he touches home plate. In other words, a legal tag on the runner (or a tag on the runner while the ball is in the glove) is required to retire him at the plate.

That’s why the best interpretation is that the catcher must apply a legal tag or make a play on the runner to record the out. If the runner reaches home before any tag is applied, he scores safely, even if the catcher has the ball. The other options don’t fit because catching the throw alone doesn’t retire the runner, the ball isn’t automatically dead just from the catch, and an error charged to the pitcher isn’t determined by this plate-play scenario.
