New York Mets vs. Seattle Mariners Prediction

I’m on the under in this game. I just think this is going to be a bit of a lower-scoring game as the Mets have been a low-scoring team at times for much of the season and Emerson Hancock has been pitching well in his own right. Add in the pitcher-friendly nature of T-Mobile Park, and I think this one comes in under the total.

Chris Ruffolo's Pick: Under 7
