Today I’m going to introduce slider ball and curve ball.

Your hand should be gripped to the seam very similarly. But they are different in how you should throw the ball.

Slider ball is bending the inside to the outside. So right hand batters are deceiving most of the time. But if people were throwing the slider ball to center, the batter can hit it very easily.

Curve ball is bending the upside to underside. This ball is flying like a fastball but it falling to down on home plate.

Therefore, I caught the ball difficulty that my friend was throwing that ball.
