Can I bring the ball inside the wrist in order to throw a riser?

Yes. Very difficult pitch to master. This was my strike out pitch in my younger days. The ball is inside the wrist with a locked elbow on release. I will spin the fingers up, thumb down in order to get the desired 6 o’clock to 12 o’clock back spin. If you throw the pitch fast enough it will rise. You can get a lot more rotation with this release vs. palm down, but the release point is very fine. The faster you throw this pitch the more it will move.
