Among the many different types of sweet spots there are for baseball, there are two main ones that need to be focused on; the nodes sweet spot and the center of percussion sweet spot. These two sweet spots, when targeted correctly, will let you hit the ball at maximum power with minimal hand sensation.
The nodes on a baseball bat is the general place where you want the ball to hit to maximize its traveling distance. The sweet spot is located in between two nodes and is often the place on the bat where the impact feels best for the batter, while the center of percussion depends on the grip on the handle of the bat.
You know you’ve hit the ball the wrong way when it just doesn’t feel right; your hands sting, your forearms ache, and the bat vibrates. You could probably hit the ball a number of times before your hands get red and sore or the bat breaks. There’s often an off sound when you hit anywhere but the right place.
