Bill - This is the best set of tips I can give you. I play adult league baseball, and use a lot of this in my at bats:
- Be Patient (sorry...couldn't help myself) - more specifically, until you get two strikes, pick an area of the plate and a specific pitch type (i.e. Fastball inside, low and away breaking pitch, etc.). If it doesn't come, don't swing. You shouldn't be swinging by reflex until you get two strikes. This doesn't mean wait until you have 1 strike, but that helps as well. Pick a pitch and an area, and sit on it.
- It's tough, if you K or get out on a sequence of pitches, try to remember them. This is going a little far, but I actually have a pad next to my gaming chair where, if I strike out, I just scribble the pitch and location for my next at bat. Pitcher's DO have tendencies in this game (and they don't even have to advertise it to make a good game

) and WILL try to get batter's out with the same stuff if you continue to swing. This has helped me immensely interms of getting a batter back on track after a bad at bat.
- Don't be afraid to take pitches. This kind of goes along with the first tip, but a lot of people think if they take a borderline strike it is a failure. A lot of the time it is a good pitch that you couldn't hit anyways. Two strikes is different, you should be fouling off anything close, but before two strikes, borderline pitches should only be swung at if you guess around that area. One big thing about this game is if you have the Umpiring Zone on Wide, there are some borderline strikes that will go your way...people seem to have the idea that all of them go the way of the pitcher, and that simply isn't true.
Hope they help, Bill. Most are pretty much common tips, but they really work in this game. As for the arm strength thing, as I said, with accuracy down, it really does make the game realistic.
