: Liked your article about Kenley Jansen, but its too bad you didn’t ask him about any of the other stuff he’s been doing to vary the use of the cutter including:

Quick pitches with the new rules for using a stretch position as a ‘windup’

The more prominent use of his slider

The addition, in that very at bat you linked against Sean Rodriguez, of a hesitation move. In the Rodriguez AB, he threw a strike, did a Kershaw-style bounce leg kick for strike 2, and then quick-pitched strike 3. You can see on strike 2 that Rodriguez ends up on one foot for a couple seconds and is completely off-balance.
