Diamondbacks vs Giants Prediction

The Diamondbacks are 8-1 in their last 9 meetings against the Giants and have won their last three visits in San Francisco.  

In this Diamondbacks vs Giants Prediction, the Diamondbacks are coming as -130 road favorites. The Diamondbacks have been the hottest team in baseball with a 9-1 record in their last 10 games and are putting Soroka on the mound, who has been excellent this season and in great form, with just four earned runs across his last four starts. Arizona also has a better offense and is the best team against righties in the past couple of weeks and I expect them to keep rolling today and finish the series sweep.
