Odd Pitching Delivery

[sthomas13100]

Doing a summer league game last night and had a pitcher doing something I've never seen.  I asked the pitcher were he came up with the idea, he said its something Clayton Kershaw does.  Well, I tried this morning and watched several Kershaw videos and did not see exactly the same thing, so I'm going to describe it.

From the stretch with runners on base, lifts his non-pivot foot up and comes back down and does a toe tap on the ground, then extends out as he is delivering the pitch.  Kershaw does come back down, but stays 1-2" above the ground (I think this is called a power "L").  The kid did not technically stop his motion with the toe tap, but it just didn't look right.  He was not a good pitcher and only pitched a couple of innings and walked half the batters. 

2 question;  have you seen this delivery before, and would you balk it?

1) Yes

2) No.  The delivery is still continuous, F1 isn't "pushing off again" with the pivot foot, don't interpret it as "more than one step" (or whatever the specific rule wording is.

Robb Nen used to do that.

Went and looked at Robb Nen video, that is the exact motion.
