Houston Astros vs. Seattle Mariners Prediction
I’m on the under in this one. Both of these teams are struggling offensviely right now and neither one is one that I really feel like backing if we’re being 100% honest. The under just seems like the play because of inefficient offense and I think this could easily be a first to 3 wins type of game. Give me the under.
