There were a lot of interesting stories in the book that I did not know. As Pedro tells it, Schilling's ankle injury resulted from Schilling adopting Pedro's technique of "hooking the rubber" where the pitcher's foot is partially on the rubber during the delivery. Shill noticed this with Pedro in Spring Training and they talked about it. Most pitchers just have only the side of their foot next to and touching the rubber as they deliver the ball. Pedro always had part of his foot on top of the rubber. It gave him more stability and leverage when delivering the ball. When Big Schill tried it, it added a couple mph to his fast ball so he stayed with it. It pinched his ankle joint and damaged the nerve. Doctors warned him the he would get necrosis in the joint if he continued, but he was having too much success and he continued until the point where he needed regular injections of numbing agents. Pedro believes that at age 37 and with Schill's big body it was too late for him to incorporate the technique.
