Cardinals vs Marlins Prediction 

St. Louis comes into this matchup on a five game winning streak and they have scored at least seven runs in three straight. The Cardinals are 6-3 on the road this year, while the Marlins are 8-5 at home. Miami has lost four of their last five games and they have allowed 5+ in all four of those losses. The Marlins are starting Meyer, who has allowed 3, 1, 2, and 3 earned runs in his four starts, while McGreevy has allowed two earned runs or fewer in three of his four starts. I really like how St. Louis is hitting the ball right now and I think they have the pitching advantage, so I like the Cardinals to get the win here.
