Mariners vs Astros Prediction
I’m not excited to back either of these teams that can’t hit the baseball. The Astros have shown more signs of life, but that’s not saying much, and they have yet to string two wins together. The Mariners are too talented to stay in this funk for long, and Castillo is probably more trustworthy than Brown, even if the Astros pitcher has been solid through two starts. At home and with an all-star caliber pitcher, it’s hard to turn down the Mariners and the plus money. That offense is also due for a breakout performance. I’ll take a shot with the Mariners.
