Marlins vs Braves Prediction 

Atlanta stayed hot with another win on Wednesday night and they have scored 8+ runs in three of their last four games. The Braves are 18-8 on the road this year, while the Marlins are 15-14 at home. Miami has lost three of their last four games and they have allowed 5+ runs in four of their last five. The Marlins are starting Alcantara, who has allowed two earned runs or fewer in three of his last four starts, while Strider has allowed four earned runs over 14.2 innings. I am still not sold on Strider coming back from injury and Alcantara has been fine, so I like the Marlins at home in this one.
