Yes. When the pitcher and catcher want to intentionally walk a batter, the catcher will extend their glove hand all the way to their side, which is outside of the batter’s reach, and the pitcher will throw it to the catcher’s glove.

Not having a ball in the game, per se, that seems like it should be illegal.
Though there’s an infamous “underarm bowling incident” in Australian/New Zealand test cricket that’s similar, was legal, but scandalous.
