1. I would not call an illegal pitch unless she replanted further towards the plate. You must call the intent of the rule which is the pitcher cannot gain an advantage on the batter. If advantage is gained-bam! I've got an illegal pitch.
2. STRONG warning--the pitcher cannot put any foreign matter/object on the ball. She can use a resin bag under the supervision of the umpires. I've never understood why we blues can't 'rub up' the balls like Major League. Probably cause the organizations are too cheap to import Delaware mud!
