Seattle Mariners vs. Detroit Tigers Prediction

I’m on the Mariners in this one. I just think that the Mariners have the edge in pitching across the board over Detroit and we got a taste of that in Tuesday’s matchup as Logan Gilbert was fantastic despite struggling on the road for much of the season. Seattle’s finding timely hitting and I think they do so here as well to pick up another win and to close out the series. Give me the Mariners.
