Miami Marlins vs. San Diego Padres Prediction

I’m on the Padres in this one. I just think that Miami is cooked and while the Marlins have shown some fight down the stretch, it’s just too little too late as far as I’m concerned. San Diego is playing lights out right now and I think they get the job done in this one as well to draw first blood in the series. Give me San Diego.
