Mariners vs Rockies Prediction

I’m on the Mariners here. It would be nice to know who both teams are sending out here, but given the state of both teams and where they’re at, I’m not sure if it matters. Seattle’s feeling themselves in a big way after that big showing on the weekend against Houston, and Colorado’s just playing for some positive vibes going into next year. The Mariners are just white-hot right now and aren’t a team I’m looking to get in front of, especially when Colorado is the alternative. Give me Seattle here.
