technique is what you make of it. i think that a lot of americans would argue that there is A LOT of technique in fouling off countless pitches, and to finally solidly hit the one that you want. The difference in bat height between intentionally fouling a pitch and hitting it is a matter of inches. Not to mention that with the avg pitch, the batter has 1 second or less to: pick up the pitch, evaluate where you think it will go, decide whether its worth hitting, and making the decision to hit or not to hit it, all in time to actually swing. And with the avg pitch at about 90mph (~145kph) that is not easy.
And if you look at the movement that pitchers can put on a ball, I can't even begin to go into the technique that pitching demands. A couple degrees in arm rotation early in your release, the ball sails over the catcher and a runner from third scores, and a couple degrees late the ball hits the dirt and you look like an idiot. Baseball is a superbly rich sport in terms of technique.
