San Francisco Giants vs. Tampa Bay Rays Prediction

I’m on the Giants in this one. I get the case to be made for either side in this game because it’s a tricky pitching matchup when both teams have struggled against left-handed pitching. That being said, I think this is more of a 50/50 matchup than this line would indicate, so to see the Rays as heavier favorites here, leans me towards the Giants based on the value. I’ll side with San Francisco in this one.

Chris Ruffolo's Pick: San Francisco +130
