Best pitching grip for velocity

what is the best pitching grip to use when trying to get the most velocity out of the pitch?

4 seam fastball and if you dont know how it looks check out the Different Pitching Grips

i found out that the most velocity i can get from a grip itself is a 4-seam fastball with my thumb curled under the ball. i can really rest the ball on my two fingers and get a good zip.

4-Seamer.

It doesn’t matter if you use a 2-Point, 3-Point, or 4-Point grip.
