Cleveland Guardians vs. Seattle Mariners Prediction

I’m on the Guardians +1.5 here. I just think this has all the makings of a tight matchup, where it turns into a battle once again until the game is decided late by the bullpens. I think the tight nature until late in the opener kind of summarizes that up, and I think I’ll take Cleveland +1.5 as a result.

Chris Ruffolo's Pick: Cleveland +1.5
