Nationals vs Marlins Prediction

The Nationals are 5-2 in their last 7 meetings against the Marlins but both teams are tied 2-2 in their last 4 visits in Miami.

In this Nationals vs Marlins Prediction, the Marlins are coming as -125 home favorites. Foster Griffin is coming off back-to-back shutouts for the Nationals, who have the 4th-best offense in baseball and are facing a Marlins squad that has been struggling against lefties, with just 3.1 runs/9 against lefties. The Nats have been better on the road with a 12-7 record and are 3-1 in their last 4 games, so I like them as road dogs in this spot. Take the Nationals on the moneyline.
