Cardinals vs Padres Prediction

St. Louis comes into this matchup after winning three of their last four games and they are looking to complete the sweep here. The Cardinals are 21-16 at home this year, while the Padres are 18-16 on the road. San Diego has split their last four games, but they have allowed three runs or fewer in four straight. The Padres haven’t announced their starter, while Leahy has allowed 3+ earned runs in three of his last four starts. It is tough to call without knowing San Diego’s pitcher, but I like the under here, as San Diego is the lowest scoring team in the MLB.
