Here is a baseball pitch grip generally thought of as a movement pitch, or somewhat similar to cut fastball, a cutter or sinker. The two seam fastball is a pitch that requires a slightly tight grip and deeper in the throwing hand compared to the four-seamer.

In pitching a two-seam fastball, the position of your index and middle fingers are kept directly on top of the narrow seams of the baseball. (See above photo).

Then, keep your thumb on the bottom side of the baseball and on the silky leather in between the narrow seams.

The two seam fastball pitch requires a firm grip to give essential friction; And this is a good advantage to cause the baseball to change direction, it can “back up” or “run in” to the throwing hand side of the plate. It slightly reduces the speed of the pitch as well, which is slower than four-seam fastballs.
