Free MLB Betting Insights for 5/18/25
Sunday’s matchup pits Washington right-hander Michael Soroka against Baltimore’s Zach Eflin in a duel that favors the home team on paper. Eflin, sporting a 3–1 record with a 3.13 ERA, has been one of the few bright spots in the Orioles’ rotation and will be counted on to go deep into the game and give his team a chance to salvage the series. Soroka, by contrast, is still trying to find his footing in the Nationals’ rotation, carrying a 0–2 record and a 6.43 ERA into the game, and will need to navigate a lineup eager to bounce back. While the Nationals’ offense has been rolling, they’ll need Soroka to avoid early trouble and lean on a bullpen that’s quietly stabilized in recent weeks. Baltimore, playing with a sense of urgency and pride, will look to get to Soroka early and give Eflin a cushion to work with, but their recent inability to execute in critical situations has been their undoing. If Washington can keep applying pressure with early offense and maintain defensive sharpness, a sweep is within reach. For the Orioles, it’s now or never to respond before the series and their season outlook begin to further spiral. Sunday’s contest will test resilience on both sides—Washington’s ability to sustain momentum, and Baltimore’s resolve to snap out of a slump—and whichever team meets the moment will carry a heavy swing of momentum into the upcoming week.

Washington Nationals MLB Preview
The Washington Nationals head into Sunday’s finale of the Beltway Series with confidence and a chance to complete an impressive road sweep over their regional rivals, the Baltimore Orioles. With back-to-back wins by scores of 4–3 and 10–6, the Nationals have found a rhythm that’s eluded them through much of the season, and now sit at 20–27 with a chance to close the gap in the NL East standings. This turnaround has been sparked by a rejuvenated offense that has produced 14 runs over the first two games of the series, led by breakout rookie James Wood, who leads the club with 12 home runs. Wood has quickly become one of the most dangerous bats in the lineup, pairing raw power with emerging plate discipline to give the Nationals a true middle-of-the-order threat. Nathaniel Lowe has complemented him with clutch production of his own, leading the team with 33 RBIs and providing consistent left-handed pop that has come up big in key moments throughout this series. The Nationals’ approach at the plate has improved markedly, showing more patience and the ability to capitalize with runners in scoring position—a far cry from the early weeks of the season when they struggled to manufacture runs. On the mound Sunday, right-hander Michael Soroka will look to overcome a rocky start to his campaign, carrying a 0–2 record and a 6.43 ERA into what could be a pivotal outing in determining his role in the rotation moving forward. Soroka has shown flashes of the command and poise that once made him a standout in Atlanta, but injuries and inconsistency have kept him from finding a groove.
Against an Orioles lineup with power threats like Gunnar Henderson and Anthony Santander, he’ll need to keep the ball down and avoid falling behind in counts to avoid giving up early damage. Fortunately for Soroka, the Nationals’ bullpen has quietly become a stabilizing force, closing out tight games and bridging the gap when starters fail to go deep. Defensively, Washington has remained sharp, limiting errors and showing improved communication and range up the middle with CJ Abrams and Luis García forming a strong double-play duo. With two straight wins in hand and the Orioles reeling, the Nationals have an excellent opportunity to not only sweep the series but also carry positive momentum into the next leg of their road trip. The key will be staying aggressive on offense, keeping pressure on Baltimore’s pitching staff, and getting five or more competitive innings from Soroka to avoid overtaxing the bullpen. For a team still finding its identity in a tough division, a road sweep against an AL opponent could be the type of spark that turns potential into progress. If the bats stay hot and Soroka finds his rhythm, Washington could walk out of Camden Yards with their most complete series performance of the season.

Baltimore Orioles MLB Preview
The Baltimore Orioles return to Oriole Park on Sunday looking to salvage the final game of the Beltway Series after back-to-back defeats have dropped their record to 15–29 and extended their losing streak to five games. It’s been a frustrating stretch for a team that was expected to be more competitive in the AL East, and manager Brandon Hyde now faces mounting pressure to ignite a response from a group that has struggled on both sides of the ball. Offensively, the Orioles haven’t been able to generate momentum, producing just nine runs over their last three games and failing to capitalize with runners in scoring position. Gunnar Henderson remains one of the few consistent bats in the lineup, leading the team with a .281 average and continuing to provide spark at the top of the order. Anthony Santander, despite leading the team in RBIs with 44, has cooled off in recent games and will need to rediscover his power stroke to help Baltimore keep pace with Washington’s surging lineup. The Orioles’ inability to deliver big innings has forced their starting pitchers to operate with minimal margins for error, a scenario that’s worn down their already-struggling bullpen and led to late-game breakdowns, like the one seen in Saturday’s 10–6 loss. On the mound Sunday, Zach Eflin represents Baltimore’s best hope to avoid the sweep. Eflin has been one of the few dependable arms in the rotation, bringing a 3–1 record and 3.13 ERA into the matchup.
Known for his ability to work deep into games and limit walks, Eflin will need to keep the Nationals’ offense in check by mixing pitches effectively and inducing weak contact, especially from hot bats like James Wood and Nathaniel Lowe. The Orioles will also need better support from their defense, which has been shaky of late, allowing unearned runs and missing double-play opportunities that have extended innings and inflated pitch counts. Behind Eflin, Hyde will be hoping the bullpen can bounce back and hold leads should the offense finally break through, though recent trends have not been encouraging. The Orioles’ relievers have struggled with command and have been vulnerable to home runs in high-leverage moments. A sharper effort across the board—timely hitting, clean defense, and reliable pitching—is needed if Baltimore is to snap their skid and avoid being swept at home by a struggling but surging Nationals club. Sunday’s finale is more than just another game—it’s a potential turning point. A win would not only end the losing streak but could restore some belief in a roster that has talent but has underperformed in every key phase this month. Eflin gives them a fighting chance, but he’ll need help from a lineup that must wake up against a shaky Michael Soroka. If the bats come alive and the defense holds, the Orioles can still salvage pride and momentum before continuing their homestand.
