[shipwreck]

I was watching one of the WCWS games a couple of days ago. The third base umpire called an illegal pitch because the pitcher slid their foot off the back of the PP during the pitch. Their arm never came out to signal a DDB. They showed it on instant replay numerous times and the umpire was in full view the whole time. That umpire was the one explaining what the pitcher did wrong so that should have been the one who called it, right? Just wondering since you cannot get much insight from the announcers. Dave
