This is not video doctor. This is the effective delivery of a Major League Knockball. What makes it effective and what is difficult to do is the lack of rotation while throwing this 70 km / h pitch. To drive a ball in like this, with such unpredictable movement, is very difficult for the hitter. It’s also a difficult pitch to catch. Many catchers have to use specially designed gloves just to catch jugs that mostly throw knuckle balls.

Instead of spinning like a fast ball at a speed of 2,500 rpm, knuckles seem to float through the air as if they were hanging in space.
[Baltimore] Orioles video content creator Johnny Douglas caught the prospect Mickey Jannis throwing the knuckle ball Saturday during a practice game against the Detroit Tigers. Jannis (33) is a former 44th round trying to bring the knuckle ball back. The last full-time pitcher to use it was Steven Wright, who has not appeared in an MLB match since 2019.
Douglas’ work with the camera also deserves praise. It is already difficult to follow a pitch of more than 70 km / h from the hill to the home plate, but at the same time reaching the focus level with the lens is an impressive achievement.
