Team Analysis
Miami Marlins
The Marlins enter with a 65-73 record and a balanced 5-5 stretch across their last 10 games, highlighted by 5.4 runs per game over the last five. That production signals enough offensive rhythm to separate from a Washington team that has been far less efficient at the plate. Kyle Stowers’ consistency has been a stabilizer in the lineup, giving Miami the reliable bat needed to maintain scoring pressure on the road.
Although the Marlins went 2-3 in their last five, their road record sits at 34-37, demonstrating they can generate wins away from home. Agustin Ramirez and Otto Lopez have provided secondary production that keeps the lineup from being top-heavy, a key factor against a Nationals roster struggling to match output. The Marlins’ ability to outscore inconsistent teams makes them the sharper side in this matchup.

Last 5 Games: 2-3 (5.4 RPG)
Last 10 Games: 5-5 (4.4 RPG)
Washington Nationals
The Nationals sit at 54-83 with a 2-8 record across their last 10 games, averaging only 2.7 runs per contest in that span. Their last five games have been similarly poor, producing just 2.6 runs per game, which highlights a lineup stuck in a scoring slump. James Wood has provided occasional power, but the lack of consistent support around him has left the offense stagnant.
Washington Nationals’ home record of 28-42 highlights their struggles in this venue, where opponents have routinely kept their lineup suppressed. CJ Abrams and Luis Garcia Jr. have contributed flashes of production, but the team’s inability to string together scoring stretches has made them unreliable. With such limited offensive momentum, the Nationals lack the tools to keep pace with Miami Marlins’ steadier attack.
- Batting Average: 0.243
- Total Runs Scored: 573
