Phillies vs Mariners Prediction
The Phillies are 4-1 in their last 5 meetings against the Mariners but are 1-3 in their last 4 meetings in Seattle.
In this Phillies vs Mariners Prediction, the Mariners are coming as -110 home favorites. I like the over in this one. Yesterday was supposed to be a pitcher’s duel and the total was set at just 6.5 runs and there were 11 runs scored with Gilbert and Wheeler on the mound, so I expect another high-scoring affair with Nola and Kirby. The Mariners’ bullpen has been in terrible form and both offenses have been red-hot, averaging 13.3 runs per game combined against righties in their last 10 games respectively and 12.2 runs per game overall. Take the over 7.5 in this one.
