Marlins vs Phillies Prediction

The Marlins are 4-1 in their last 5 meetings against the Phillies and are 1-3 in their last 4 visits in Philadelphia.

In this Marlins vs Phillies Prediction, the Phillies are coming as -235 home favorites. I like the Phillies in this one with Zack Wheeler on the mound, who has been struggling mightily lately but will bounce back today at home. The Marlins’ bullpen has been atrocious in their last 5 games and they are scoring just 4.2 runs per game, while the Phillies average 6.9 runs per game against righties in that span and have four consecutive wins. Take the Phillies to win this one comfortably at home and cover the runline.
