My son always tries to throw a competitive pitch 0-2. It’s either a breaking ball that starts over the plate but ends up a ball or a sinker/2 seam that does the same thing on the other side. No chance they can hit it hard, might get a swing and miss, or sets them up, for the next pitch. He never throws anything straight 0-2. As mentioned above, a weak ground ball or a popup 0-2 is just as good as a strikeout.
