Mariners vs Pirates Prediction

The Mariners have won their last 7 meetings against the Pirates, having won their last three visits in Pittsburgh.

In this Mariners vs Pirates Prediction, the Mariners are coming as -140 road favorites. I like the Mariners in this one with Bryce Miller on the bump, who has been elite this season, never given up more than 2 runs in all of his six starts. On the flip side, Bubba Chandler has given up at least two runs in 8 of his 9 starts this season and has been weaker at home. On top of that, the Mariners have the 7th-best bullpen in baseball, so I expect them to win this one on the road.
