Marlins vs Nationals action returns Monday night as Miami and Washington prepare to close a four-game series at Nationals Park. The opening pitch is scheduled for 6:45 p.m. ET, with the Marlins entering as the slight favorite after a convincing 6-2 victory on Sunday.

The betting lines reported by Athlon Sports were listed as of 8:13 a.m. ET Monday and could change before game time. Miami’s negative moneyline indicates that oddsmakers expect the visitors to have the edge, though the matchup remains competitive given both teams’ inconsistent recent form.

Ryan Gusto Gives Miami a Promising Start

Ryan Gusto will take the mound for Miami, bringing a 1-3 record, a 3.98 ERA, a 1.33 WHIP and 7.5 strikeouts per nine innings into the finale. His recent performances provide encouragement for the Marlins, particularly after he held Boston scoreless over 5.2 innings on Aug. 26.

Gusto is 1-1 with a 1.85 ERA across his last five starts, a significant improvement from his 5.31 ERA over the preceding 13 appearances. He also faced Washington on Aug. 21, working four scoreless innings while allowing five hits. Although he did not receive a decision in that game, his ability to limit the Nationals’ offense could prove important Monday.

Washington is expected to counter with Will Dion, who is scheduled to make his first start of the season. Dion’s recent results have been mixed. He has allowed only 3.4 hits per nine innings across his last nine appearances, but that figure rose to 13.8 hits per nine innings in his previous eight outings.

Explosive Bats Could Decide the Finale

Miami’s offense has several players carrying positive momentum into the final game. Heriberto Hernández has reached base at least once in 16 consecutive games, while Otto Lopez has extended his on-base streak to 13 games. Their ability to create traffic could put early pressure on Dion and the Nationals’ bullpen.

Not every Marlins hitter is producing at the same level. Esteury Ruiz has gone 14 straight games without an extra-base hit, and Griffin Conine has failed to record one in nine consecutive contests. Catcher Joe Mack is batting .167 with a .192 on-base percentage and a .208 slugging percentage over his last nine games.

Washington has its own contrasting trends. Daylen Lile has been one of the Nationals’ hottest hitters, posting a .429/.514/.929 slash line across his last eight games. Brady House has also contributed, going 4-for-11 with four runs over his past four games.

Meanwhile, Abimelec Ortiz, Harry Ford and Nasim Nuñez have struggled recently. Ortiz is batting .159/.213/.205 since Aug. 18, Ford has posted a .120/.241/.240 line over his last nine games, and Nuñez is hitting .105/.173/.116 since July 28.

Critical Late-Season Test for Both Clubs

Miami enters the matchup at 69-68 and has gone 5-5 over its last 10 games. The Marlins won three straight against Washington earlier in the month, but they have since lost four of six, making Monday’s finale an important opportunity to regain momentum.

The Nationals are 65-74 and have also gone 4-6 in their last 10 games. Their series has included a 9-2 win, a dramatic 5-4 extra-inning victory and Sunday’s 6-2 defeat. Washington’s recent bullpen issues have added pressure to its offense and starting pitching, particularly in close games.

CJ Abrams will be a player to watch after going 0-for-4 with three strikeouts Sunday. He is batting .091 over his last eight games against Miami, compared with a .280 average across his previous 123 games.

Athlon Sports projects a 5-3 Marlins victory, citing Miami’s recent success in the series and Hernández’s steady presence at the plate. The prediction leans toward Miami, but the Nationals’ home-field advantage and the uncertainty surrounding Dion’s first start could make the finale a compelling contest.
