what the pitcher threw at you.

If they just throw fastballs, sliders, probably no chance.

But a curve ball, one of the strange things is you can pick up a curve ball better with LESS experience and generally make a good swing.

The other thing is if you actually played baseball beyond high school. With real pitching that could range into the 90s. If not, forget it, you won't have the muscle memory to even try and train your brain to see the ball off the pitchers hand, and if you can't see it, you can't hit it.

Takes a lot of work to learn where different pitchers deliver the ball from. One reason Jansen for the Dodgers has been good with his pitches is that he has a different angle that some players only see a couple times a season. But teams get film, and then you have a long series where he gets used a few times and suddenly you break the code on a guy who hasn't learned to change up his pitches like he should, and that is how he loses games.
