Washington Nationals vs. Seattle Mariners Prediction
I’m leaning towards Seattle here. I get that Washington is a bit of a tempting underdog, but the thing is that Mitchell Parker really struggled in his road outings last year, and I’m not about to think that all of a sudden, that’s changed. The Mariners have cooled off since their strong run earlier this month, but there’s still value in backing them in spots, and I think the Mariners get the job done here. Give me Washington in this one.
