Guardians vs Mariners Prediction 

Both of these teams come into this series struggling, and they are falling behind in their division races, so this is a big series for each side. The Mariners are 16-17 at home this year, while the Guardians are 16-17 on the road. Seattle has allowed 23 runs in their last three games, and they are starting Castillo, who has allowed three earned runs or fewer in four of his last five starts. The Guardians are starting Williams, who has also allowed three runs or fewer in four of his last five starts. We normally don’t get a ton of runs in Seattle, and I think we are going to see another low-scoring game. Take the under here.
