When I pitched I always when high and tight when a guy squared around to bunt. Guy squared one time and I threw inside and pissed him off . Threatened me if I threw at him again. Next pitch he squares way early and I go inside. He never had a chance to react, hit him square in the nuts, fell back full spread eagle and hit the ground. When he finally shook it off my catcher, football player also, escorted him towards first base.
Back in the heyday of baseball, 'dusting' the batter (also known as 'chin music') was commonplace.. Roger Clemons, Nolan Ryan, Kofax, you name 'em - and they threw 'em.. In today's game I don't believe anyone now truly aims to hit the batter above the shoulders - but ribs might be another matter..
