Vaughn is nervous, that AB vs Cobb where he threw 2 or 3 straight splitters (all were low out of the zone) in a row and Vaughn swung through all of them, on 0-2. he needs to figure out how to relax. When Vaughn is himself, there's no way he strikes out on a pitch out of the zone on 0-2, he would know the count in that situation and that a chase pitch is coming
