I'm just starting out so I went with the easiest level (rookie) for both hitting and pitching. I usually do that with a new game until I start to get the hang of it, then gradually bump it up a couple notches. Only thing I adjusted was CPU pitch speed because I was having a helluva time reading balls/strikes.
Considering that I'm using rookie level pitching difficulty and still gave up 14 runs and 8 bombs just shows you how god awful I am at pitching
