Philadelphia Phillies vs. Seattle Mariners Prediction
I’m on the Phillies in this one. I’m just having a hard time backing the Mariners in their current form, as the Mariners have been so inconsistent offensively. The Phillies keep on finding ways to win including a 6-run bottom of the 9th on Sunday to walk off St. Louis and cover the run line and I think we have more of the same here in all honesty. I think the Phillies take care of business as Gilbert’s been less effective at home this season so give me Philadelphia here.
