I am other than a statistician obviously. My observation on Royals pitching staff is general, and other factors besides bare stats are taken into my account: timing of removing the starter, intuitiveness regards removing starter before implosion instead of after, use of starters in terms of injury prevention and performance over the long haul–e.g. with multiple high pitch innings do you remove at that point or persevere, and which of those will affect the subsequent start, conditioning as it relates to performance and injury prevention, etc. etc. Stats are valuable and would uncover some of this. Some of it is based on experience in athletics. You may poo poo if u want. Whether the Royals management is deficient in these various aspects or very good, I don’t known because i follow less closely than many. I do see merely from the box scores that stats would show Yost likely the least intuitive manager in baseball and maybe in history in terms of putting in the correct reliever in a situation or a night, timely removing starters, etc. Could be wrong, but, that’s rare
