San Francisco Giants vs. San Diego Padres Prediction
I’m on the Padres in this one. I think that Sears gets a really favorable matchup here, as the Giants have been horrible against left-handed pitching for the better part of the second half of the season so far and I don’t expect it to get better here. Roupp has a lot of upside, but he’s had issues of his own, and the Padres have been really solid against right-handed pitching and I think they get it done here. Give me San Diego.
