The Marlins Can Win If…

Miami’s offense needs to find its spark after dropping Monday’s matchup 5-2. Connor Norby and Otto Lopez each had two hits in the loss, but run production stalled late. The Marlins have proven they can hit, ranking 7th in doubles (231) and 9th in batting average (.249).

Eury Pérez takes the ball with a 4.04 ERA and sharp 1.04 WHIP. His ability to limit base traffic is key, especially against a Nationals lineup that likes to swipe bags. Facing Mitchell Parker — who carries a 5.94 ERA — Miami has a clear advantage on the mound and must capitalize on that mismatch.

The Nationals Can Win If…

Washington enters this one with momentum. Cade Cavalli held Miami in check in Monday’s win, while James Wood belted his 27th homer and drove in two. Jacob Young also added two hits and an RBI, showing this young lineup can contribute from multiple spots.

The Nationals sit 10th in doubles and 7th in stolen bases (116), adding extra-base power and speed as pressure points. Mitchell Parker, despite his 5.94 ERA, has shown flashes with seven wins. If he can keep traffic down early, Washington has a path to another upset.

Betting Outlook

The Marlins are favored at -135, and projections back that up. Miami’s more balanced lineup and stronger starting pitching give them a narrow edge, with my model calling for a 5-4 Marlins win.

At a total of 9 runs, the lean is on the under (-112). Neither bullpen is airtight, but both lineups have struggled with consistency, and Pérez has the tools to contain Washington’s offense.
