San Francisco Giants vs. San Diego Padres Prediction
I’m on the over here. I was on the under on Monday but I think the over is the way to go here. I didn’t love how Logan Webb looked against the Yankees in his opening start, and that was at home where Webb’s been far more effective his entire career, and now faces a Padres team that’s had his number over the years. On the other side, I don’t know how German Marquez nabbed another starting job at the MLB level, but I think that this is headed for a higher-scoring game so give me the over here.
