Braves vs Mariners Prediction

I’m on the Braves here. I just think that you’re rarely going to get a pitcher like Spencer Strider at this kind of price, and it’s not one I’m wanting to pass on here. Furthermore, I do think it’s a matter of time before he gets his act together. Castillo still has his fair share of issues, and I still think that Strider is a quality option that is the better one here. Give me the Braves.
