Well pitching seems to have a lot more control.
Basically the catcher suggests a pitch and a location. You can either agree to it by selecting the suggested pitch and aiming the ball cursor over the yellow target, or you can select the pitch you want and use the suggested location or a different location.
From that point your ability to hit where you targeted with the cursor depends on the pitch gauge. When youre rested you get a bar at the low range automatically, and when you hit the high range of the meter you set the top bar (dictating power) and on the way back you want to generally hit the point in between those two bars.
However, you can trick batters on the fly, especially in vs mode by deliberately not hitting the center of that range. That last bar afaik represents when in your pitch arc the ball is released. The higher you pop the third bar the earlier the release the higher the pitch. The lower the third bar hits on the gauge the later the release the lower the pitch. In general its a bad idea to try early releases unless youre certain youre pitching at an initially low designated target or you will almost always overshoot the pitcher and I have yet to see a pitcher in the game compensate well for an overthrow. Its easier to take a chance throwing really low since most catchers stop balls in the dirt preventing extra bases.
Now, as your pitcher gets tired he loses the ability to throw really powerful pitches, but accuracy remains relatively on. However, if you start losing the game badly you retain most of your power but lose a lot of control, which is represented by the lack of the initial first bar in the pitching gauge. At this point you still set the second and third bars, but you kinda have to GUESS where that first bar WOULD have been, and therein lies the challenge.
Also its good to mix up your pitches to ensure when you need to throw a certain pitch its bar shows enough charge or whatever it is to = a great pitch.
Thats all ive got from the game so far, im doing a Road to the Show as a pitcher in the shitty minors so ive had to learn as I go.
