Phillies vs Mariners Prediction

The Phillies have won their last four meetings against the Mariners, but have lost two of their last three visits in Seattle.

In this Phillies vs Mariners Prediction, the Phillies are coming as -115 road favorites. This price for the red-hot Phillies, winners of nine straight with Zack Wheeler on the mound, is a gift and I will take it. Gilbert has been excellent as well, but has been weaker at home with a 4.01 ERA and has given up 3+ runs in five of his last seven starts. On top of that, the Mariners’ bullpen has been terrible lately, while the Phillies’ offense has been red-hot. Take the Phillies in this one.
