The Diamondbacks will open the series with their ace Zac Gallen (12-5, 3.24 ERA) on the mound. The right-hander will oppose 43-year-old left-hander Rich Hill, who is 0-2 with a 12.79 ERA in his first two starts for San Diego since he was acquired in an Aug. 1 trade with the Pittsburgh Pirates. Overall, Hill is 7-12 with a 5.17 ERA. Kind of scary rolling with the under with Hill here who can be a disaster at times, however we think he bounces back here as he really needs to come through for his team and has a lot of pride. We think runs are hard to come by and we will roll with the under here.
