Phillies vs Mariners Prediction

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.
