In a jump turn, both feet remain in front of the rubber. In this move by Cain, the pivot foot disengaged by stepping behind the rubber.

That's what I'm seeing as well. What am I missing here?

Well, one of us is. This happens so fast that a lot of action happens at 0:01 and at 0:02 (the "two-second mark" has about 12 spots you can pause it at). But as you watch the little dot move on the bottom, the 7th spot of the dot (still 0:01) shows the hand starting to remove from the glove and the foot still up. The 8th dot (now 0:02), you can see the ball in the hand, separate from glove - with the toe pointing downward, but not on the ground. On the ninth dot (still 0:02), the foot has now barely hit the ground and the ball is most obviously out of the glove.

You're accepting an incorrect definition of jump turn. It's defined more by what it isn't than what it is, and it isn't a legal disengagement.

Nothing requires that a jump turn have both feet in front of the rubber, or indeed both in the air at once. All that's required is a legal step and (if to 1B) then a throw.

If Cain hadn't thrown to first, would you have balked him? I would. Why?

His 'disengagement' and throw to first were in one continuous motion. This makes it a 'jump turn'. There was no distinct stop and drop of the hands, which to me would be a complete disengagement of the rubber. At this point, if he stopped, disengaged and then overthrew first, would be a 2 base award.

Okay, then somebody please explain how a RHP executes a "jump turn". I always believed both feet had to come up simultaneously--in other words, the pitcher "jumps", which is why the move has that word in it.

Heck, to me, this looks more like a jab-step, but he "jabs" his foot behind the rubber instead of in front of it. And since the jab is behind the rubber, it constitutes a disengagement.

And, No, I don't have Jim Evans's balk video.

Pitchers use a lot of different moves. Again: these moves are defined by what they are not. If F1 does not legally disengage, then whatever the move is must conform to the rules governing throwing/feinting to a base.

The reason the move in the video is not legal disengagement is that disengagement requires that the step be complete PRIOR to separating the hands or making any other move/step toward a base.

So Cain had to conform to the throw/feint rules, which he did (no balk). And that's why the award for the overthrow was correct.

Q.E.D.

I think a lot of people mess this up by trying to give the move a name. "Jab step", "Jump Turn". Better to look at the rules and determine if he broke one. Since he did not legally disengage, he must throw. He did. No balk. If the pitcher did exactly what we see on this video but did not throw to first, you'd have a balk.

You claimed that the ball was out of his hand before the pivot foot hit the ground. This screen shot says differently:

His foot is clearly on the ground behind the rubber and the ball is still in his hand.

Where does the rule say you have to stop and drop your hands to legally disengage? His first move was to move his pivot foot behind the rubber, thus disengaging.

I still would not balk a pitcher in this situation if he doesn't throw. It would be a very nitpicky balk, and a balk that very few umpires at higher levels would call.

He did legally disengage, so it can't be a jump turn. It was closer to a jab step, but he still put his pivot foot behind the rubber to disengage.

OK, fair enough, I understand the confusion now. I've fixed my original post. My explanation seems to clarify what I meant, but I see your disagreement now.

The ball was out of the GLOVE hand before he stepped back - not a legal disengagement - the foot movement was not part of a disengagement, therefore he's not disengaged.

So what we are seeing here is a '12 eyed miss'? 6 professional umpires miss the same call? Highly doubtful.

This illustrates why you don't understand that. A) this cannot be a legal disengagement - he has to step off BEFORE beginning to throw for a legal disengagement. B) Define Jump Turn and Jab Step ... using only the rulebook to do so. Good luck. Do you see a rule that states where the pivot foot must go to be a jab step? (PS - how could you call this a legal disengagement AND a jab step - it cannot be both... you have to throw after a jab step because you are NOT disengaged.)

This is not a "disengage first" move. After watching the video I can't believe anyone is still arguing that this was some kind of missed call.

Well after he started his move to first. It's not like the foot came back first (making him a fielder) and *then* he threw over to first base.
