John from www.YouGoProBaseball.com shows us how to grip and throw a curveball. There are two ways to throw a curve ball and one of the ways is to keep your index finger and your middle finger on the right side of the two seam of the ball. The real curve ball is that with a lot of depth and sharpness. The depth in the sense how far the ball breaks along the path. The longer it takes time to break the sharper its curve will be. And you need to feel the ball when you throw the ball, keep your fingers on top and keep your fingers on top of it and throw the baseball. The other way to throw the curve ball is to keep your fingers on the backside of the horseshoe and the rest of the things are the same. This is the way you get to throw a curve ball.
