What is up with the Reds pitching coach?

Reds down 1-0, bases loaded no outs and Singer already got 87 pitches in. Pitching coach decided to keep him in and got 1 out but gave out 2 free runs from walks. 100 pitches after then down 3-0, bases loaded one out, they decide ok maybe we should sub him out?

Are they that stupid?

All coaches and managers are stupid as fuck in the MLB. You can be up 6-0, 7-0, 8-0, and have about a 25% chance to still lose the game. The MLB is disgusting. It’s not even about variance to me. It’s about corruption this is fucking pathetic. Fuck this sport
