The Miami Marlins host the Washington Nationals on Wednesday night in what shapes up as a classic clash between two teams heading in opposite directions.
Miami enters as -130 favourites despite both clubs struggling this season, with the Nationals' woeful 5.30 team ERA (29th in MLB) making them attractive underdogs at +110.

Miami Marlins vs. Washington Nationals preview
Two clubs looking to finish the season on a positive note square off at loanDepot park Wednesday night, with the Nationals visiting Miami in what should be a competitive late-season clash.
Washington enters this matchup having struggled mightily on the pitching side, ranking 29th in team ERA at 5.30 while allowing 780 total runs this season.
Jake Irvin takes the ball for the Nationals with a career 4.91 ERA, facing a Miami offense that has been slightly more productive, averaging 4.33 runs per game compared to Washington's 4.3.
The Marlins counter with young Eury Perez, who brings a much more promising 3.84 career ERA and solid 1.119 WHIP to the mound against a Nationals lineup that has managed just 138 home runs this season.
Miami's bullpen holds a slight edge with a 63.6% save percentage, though both teams have shown inconsistency in late-game situations throughout this disappointing campaign.
With neither club in postseason contention, expect both sides to give younger players extended looks as they evaluate talent for 2026.
