Philadelphia Phillies vs. Seattle Mariners Prediction

I’m on the under in this one. You have two quality starting options in this game in Luzardo and Woo, and both have been strong in their current environments. Woo at home and Luzardo on the road. I think this is a pitcher’s duel, so give me the under.

Chris Ruffolo's Pick: Under 7
