Mets vs Mariners Prediction
I’m rolling with the Mariners here. The Mariners haven’t been great against lefties as of late, but the Mets haven’t been good against anyone in fairness. I just don’t see any value in backing them here, and Manaea hasn’t been elite since coming back from injury. The Mets are just ice-cold right now and are watching everything go down in flames around them, and I don’t see it getting better here. Give me Seattle.
