I thought I knew this

Jake80,

1. The "in contact" pitcher has feinted to 1B prior to completing a legal disengage. He has balked under 8.05(b). Good call.

2. I've always heard this referred to as a "jump spin" move, but "jump turn" sounds fine to me. When executed properly, the pivot foot does in fact normally land in front of the rubber. I don't think it would be illegal (i.e. a balk) if the pivot foot landed behind the rubber as long as the "free" foot gained "distance and direction" toward 1B. However, this is considered a move "from the rubber", so if the move is to 1B, a throw is required. Landing the pivot foot behind the rubber does not make this a legal disengage.
