Washington Nationals vs. San Diego Padres Prediction

I’m on the Padres in this one. I get the case to be made for either side in this game as the Nationals can be a tempting underdog to back, but I just think that in this situation, Mize is the better and more trustworthy starting option as we don’t really know what we’re going to get from Cornelio in this appearance, even if it’s more of an opener situation. I also think the Padres have the far superior bullpen late in this game and if it’s a tight one late, that’s where it’s going to be decided. Give me San Diego.
