"In the olden days, the umpire didn't have to take any courses in mind reading. The pitcher told you he was going to throw at you"

This quote by Leo Durocher is describing the days of baseball before the modern era. In the olden days, the umpire did not require to be able to check out the minds of the players in order to make a call. Rather, the pitcher would inform the umpire that he was going to throw at a batter. This was a common practice in the olden days, as pitchers would typically throw at batters to daunt them or to send out a message. This was seen as a way to gain an advantage in the video game, as the batter would be less most likely to swing at a pitch if they knew it was coming. This practice has given that been banned in modern-day baseball, as it is viewed as hazardous and unsportsmanlike. The umpire now has to count on their own judgement and experience to phone.
