Throw a Fastball
A fastball is a pitcher's most important pitch, and it comes in two basic varieties: four-seam and two seam (Click the diagram to the left). A pitcher cannot impart enough spin on a baseball to actually make it rise, but with its rapid backspin a fastball can be made to not drop as much as a ball thrown with minimal spin and thus appear to rise or "hop" to the batter.

A four-seam fastball (so called because from a catcher's view all four seams of the ball are seen rotating from bottom to top) is thrown with backspin. It is gripped across the seams and the middle finger should snap through the ball creating leaverage and maximum velocity.

A two-seam fastball is gripped along the seams and thrown with backspin. Because it has only two seams interacting with the air as opposed to four, it has less lift than a four-seam fastball and thus tends to sink.
