The September 10, 2025 matchup between the Washington Nationals and the Miami Marlins at loanDepot Park brings together two teams heading in opposite directions, with Washington riding a surge of momentum and Miami fighting to salvage pride in a season that has drifted away from competitiveness. The Nationals have won six of their last seven games, including two straight in this series, leaning on a combination of veteran power, emerging young talent, and just enough pitching to outlast the Marlins. Josh Bell has been the centerpiece of their recent offensive explosion, delivering multiple home runs in back-to-back games, including a six-RBI performance where he became just the second player in franchise history to homer from both sides of the plate in consecutive innings. Nasim Núñez has also made headlines with his first two career homers coming in the same game, giving the Nationals a spark from an unlikely source, while Mitchell Parker and Jake Irvin have kept the pitching staff steady enough to allow the offense to flourish. Washington has scored double-digit runs in several recent outings, putting Miami’s struggling staff under immense pressure, and their ability to sustain rallies has been a difference-maker in this series. On the other side, the Marlins have been unable to stop the bleeding, dropping game after game in a stretch that has revealed both their offensive shortcomings and pitching depth issues. Injuries, including the absence of key bat Kyle Stowers, have left their lineup thin, forcing manager Skip Schumaker to rely heavily on unproven players who have not been able to consistently produce in high-leverage moments.

Even with young talent like Eury Pérez in the rotation, Miami has not been able to neutralize Washington’s hot bats, and their bullpen has struggled to keep games close once early deficits pile up. From a betting perspective, oddsmakers have set a close line, with Miami favored at around –130 and Washington sitting at +110, and the run total at 8.5 indicates expectations for a moderately high-scoring game, though recent history between these clubs suggests the Nationals’ offense could push things higher. Washington’s recent results also point to them outperforming expectations against the spread, while Miami’s ATS record sits at 38–32, better than their overall win-loss but not reflective of the recent downturn. The key to this matchup will be whether Miami can find a way to quiet Washington’s offense, which has shown it can get production up and down the lineup, or whether the Nationals continue their run of scoring bursts that bury opponents by the middle innings. With the Nationals pushing to reach .500 and perhaps play spoiler in the playoff race, and the Marlins playing for pride and future evaluation, this game still carries weight as a test of direction for both franchises. Ultimately, if Washington continues to lean on Bell’s power, Núñez’s energy, and timely pitching, they appear poised to extend their streak, while Miami will need to summon an inspired performance at home to avoid being swept and further cementing their position as one of the league’s most disappointing teams in 2025.
