Does anyone else see a big flaw in this one? If I am reading the rule correctly, if a P is injured or ill, he can come out. But there is no corresponding "sit" rule. In other words, there is nothing from stopping a P to fake an injury and be replaced since he is immediately eligible to return the next game.
So, tactically, are we going to see a bunch of fake injuries (signaled by the coach) that will backfire and make the game even longer instead of shorter? In fact, this gives a team even longer to have the next relief guy warm up. I don't see an umpire sticking his neck out, from a liability standpoint, and calling out a P for faking.
