How About Andrew Knizner? The backup catcher has caught fire in the second half and has people clamoring for him to play over Yadier Molina. This is the same player who was worth -1.3 fWAR in his career prior to this year and the same player who many had already given up on.
Now I’m not trying to call anyone out here. I didn’t have much faith in him prior to this hot streak either. It’s just been surprising to see Knizner turn his season around so quickly.
Still, I have a hard time believing that someone who was so bad has somehow flipped a switch and become good.
