RE: Shoemaker
I understand that anti-analytics people love anecdotes and examples. Here is a good one for the Shoemaker decision.
August 16th 2020 vs Tampa Bay
Matt Shoemaker pitches three perfect innings to start the game.
Comes out for the fourth. Out, single, walk (was ahead 0-2), strikeout (of a LHB on 5 pitches, so Shoemaker still looks great).... three run homer. Blink of an eye and he has a 6.75 ERA on the afternoon.
