So the solution to beating the shift is to hit from the opposite side of the plate? That analogy doesn't fit at all. Tennis players hit cross court and straight down the line with both forehands and backhands.
If you wait a fraction of a second later and the pitch is on the inner half you just struck out or broke your bat at best. And as soon as the analytics start to show a hitter adjusting to purposefully go oppo, have fun with those 98 mph fastballs up and in.
