Pittsburgh Pirates vs. San Francisco Giants Prediction

I’m on the Pirates here. I just don’t trust Mahle and I don’t trust the Giants offensively to back him up, even against a starter in Bubba Chandler who’s struggled left and right this season with control. Pittsburgh’s got far more upside in this game and I think they get it done here. Give me the Pirates.
