Cowser's expected numbers are trending down from deep red to light red. Statcast is descriptive and it's starting to trend in the direction that our eyes can see on the field. I don't think it can be argued the results since his scorching hot April haven't been good.
I don't think Kjerstad would play the same level of defense, but I think he could out-hit him, and I'm not sure Stowers can do either over a sustained stretch of ABs but I wouldn't be against them trying. I suspect they are going to hope he can maybe get hot again and push for ROY but he has virtually no chance.
