The CPU will swing and miss if you make a good pitch (I'm playing on all star difficulty).
The draw walk slider is in the edit player section. Which btw does squat. I edited every hitter on the opposing team to have draw walk at 100 and CPU still hacked at everything. I then thought maybe lowering to zero would help, no dice they still hacked at everything. To be honest, I don't even notice a difference between 0 or 100.
Re: editing players batting stances...
I tried editing guys with generic stances and could not fond anywhere in the edit player section that would allow me to do so. Furthermore, I couldn't even find it in the create a player mode.
