I don't mean to generalize it.
But I see some stupid pitching changes very often these days.
Look at the Reds game, for example.
Bailey gives up hits and walks every single innng.
And again at the top of the sixth, he's doing it all over again. Giving up hits and walks.
And leaving him on the mound? The manager finally changes the pitcher when the bases are loaded.
Why? Why not changing the pitcher when the top of the sixth starts?
Why giving an extra pressure to his relievers and ruining the game.
This is something I really don't understand.
