Now I was just thinking and maybe someone has this answer for me, how do boxers train to punch?
Not that they are exactly the same, but the motions seem somewhat similar in that they both seem to require a great deal of abdominal rotation speed. Right? Also I'd assume (I've never boxed in my life so I completely assume) that their powerful punch originates from the ground, in other words, in their legs just like a pitcher.
It does originate from the ground- your power comes from the twisting of your hips and your footwork. So yes, strong legs and abdominals will be your greatest allies in developing a more powerful pitch. Look at Roger Clemens... motherfucker has legs like tree trunks.
Weight shift is also important (in both punching and pitching). In Physics Force = Mass x Acceleration. The mass in a punch or pitch comes from the bodyweight shifting into the pitch/punch. That's one of the reasons pitchers pitch from a "mound", because it helps them to use gravity to increase their ability to quickly shift their weight and have more distance to develop speed while throwing.
I also assume that they work to get their fist traveling at the highest velocity they can to make the hardest punch, just like I want to get my hand, even more specifically my arm traveling at the highest velocity I can to make the fastest pitch. On top of all of that, cardio is huge in both boxing and pitching.
This is done in different ways though. And your fist isn't really moving at the highest velocity- it's coming right from your chin straight out, and powered by your legs. It's not quite like a pitch where you wind up and put everything you got into one haymaker motion- that's telegraphing, and you'll get killed.
They tell you all the time not to wind up a punch because the other guy will see it coming.
So the mechanics, to me, seem different... but then I have no idea the mechanics that go into pitching, so maybe I'm wrong. It's similar, but both of them are so specific that they don't really translate exactly.
Yes, the mechanics are different. But, also a little too similar IMO. What I mean by that is that they are just similar enough that one could possibly screw up your performance of the other (at least at a very high level).
In punching maximal speed is developed via relaxation, and proper mechanics (like no telegraph, fist travels the straightest line to the target, fist moves first, etc...).
From my experience with pitching (certainly nothing really high level) it's mostly about being able to get your body into the pitch as much as possible, the strength of the muscles powering the pitch, and the ability to shut off the opposing muscles that would act as brakes and slow you down.
In other words I'm thinking that boxing training, atleast as far as abdominal, legs, and cardio (and perhaps other aspects), might be a good way to go? Anyone have an opinion on this?
Any sport such as boxing or baseball that requires extreme explosive rotational force is going to mean that you need strong abs.
I would advise you to look at Ross Enamait's stuff and go buy a medicine ball- great for explosiveness, and you can do alot of rotational work that you otherwise wouldn't be able to do with weights.
I agree with Irish that your best bet is to continue to perfect your pitching technique (maybe break the pitch down into smaller components, get those really, really good and add speed/power as you get more and more efficient in your mechanics, then add it all together and see if that doesn't help),
Strengthen the muscles that power your pitches (and yes strenthen the antagonists so as to avoid injury), and leave boxing training to those who want to improve at boxing.
Also, another great piece of equipment for rotational force development is called a "tornado ball". It's basically a medicing ball on a rope. The most popular way I've seen it used is to stand with your back to a wall, and practice rotating back and force as quickly and powerfully as possible trying to slam the ball off the walls on both your right and left.
