I have never understood the claim that there is something so mentally or emotionally challenging about pitching. If a pitcher has a smart and hardworking catcher, who will study the other teams' lineups and strengths and weaknesses, and if the pitcher has enough sense to throw the pitches called by the catcher at the location called by the catcher and has the skill to hit the location indicated most of the time, and if the pitcher has pitches which are fast and which have excellent movement, then a pitcher doesn't need to think. Just throw the pitches where and how, this smart catcher says. Pitching is not rocket science. Just mix up your pitches and be aware of the game situation and the weaknesses and strengths of your opponents and be able to put your pitches where you want them to go doesn't take a physics degree from Harvard.
