Mariners vs Red Sox MLB Betting Preview, Prediction
By Derek Carty
Editor's Note: This written best bet is a transcription from the latest episode of the Payoff Pitch podcast.
This one is strictly a projection play—it’s showing really good value and looks mispriced. We’re targeting Josh Naylor to record a walk.
You can get +330 at bt365, which is the best price on the board. DraftKings is offering +284, and I like this play down to +255.
Our projection model gives this about a 30% chance of hitting, so at +330, we're getting fantastic odds.
Pick: Josh Naylor Over 0.5 Walks (+255 or Better)
