Mariners vs Marlins Prediction

The Marlins are 4-2 in their last 6 meetings against the Mariners and have won their last three meetings in Miami.

In this Mariners vs Marlins Prediction, the Mariners are coming as -150 road favorites. I like the Mariners in a bounce-back spot on the road with their ace on the mound in Bryce Miller. Miller has been outstanding this season having the second-best ERA in baseball and will go up against Janson Junk for the Marlins, who has given up 16 runs across his last three starts and has a 1-3 record and 4.70 ERA at home. On top of that, the Mariners have a better bullpen and are better against righties in the month of July. Take the Mariners to win this one on the road.
