May 28, 2025 | 9:40 p.m. ET | T-Mobile Park, Seattle

Seattle Mariners
Moneyline Pick - Seattle Mariners (-205): B

The Seattle Mariners, currently leading the AL West with a 30-23 record, are set to host the Washington Nationals tonight at T-Mobile Park. Seattle enters the game on a decent run of form, while Washington has dropped its last two contests. The Mariners' pitching staff has been a cornerstone of their success, boasting a bullpen with a 3.64 ERA and a 1.31 WHIP, ranking overall among the top in the league.  Offensively, Seattle has shown strength at home, with key players contributing significantly to their recent success. In contrast, the Nationals have struggled offensively on the road, ranking in the bottom ten in OPS, and are dealing with injuries to key players, including a top prospect.

Given the Mariners' current form, home-field advantage, and the Nationals' road struggles, Seattle appears well-positioned to extend their winning streak. While no outcome is guaranteed, the combination of strong pitching and offensive momentum suggests that the Mariners could secure another victory tonight. Bettors might find value in backing Seattle to continue their winning ways.

Over/Under Pick - Under 8 (-110): B-

The Seattle Mariners are set to host the Washington Nationals at T-Mobile Park, with both teams aiming to capitalize on their respective strengths. Seattle's starting pitcher who is historically a very reliable arm, while Washington's lineup continues to adjust due to injuries to key players. Despite a recent three-game winning streak, the Mariners have averaged fewer than 4.5 runs per game at home this season. They will face a right-handed pitcher from the Nationals who has shown effectiveness against Seattle's top hitters in previous matchups. Seattle's bullpen remains fairly well-rested, which could play a crucial role in maintaining a low-scoring game. Both teams have struggled with runners in scoring position over the past week, and the pitcher-friendly dimensions of T-Mobile Park further suggest a game where runs may be at a premium.

Given these factors, the under on an 8-run total appears to be a prudent betting choice. While there's always a risk if Seattle's starter experiences control issues, the combination of strong pitching, underperforming offenses, and a ballpark that suppresses scoring makes the under an appealing option for bettors looking for value in this matchup.

Spread Pick - Seattle Mariners, -1.5 (-105): B

The Mariners carry clear momentum into this matchup, having taking a 9-1 blowout win yesterday, while the Nationals have dropped three of their last four. Seattle’s starting pitcher has been particularly sharp in previous interleague meetings with Washington, maintaining excellent control and limiting baserunners. On the other side, the Nationals may again be without their usual starter, who’s been dealing with a lingering arm issue, which raises concerns about Washington’s ability to manage innings effectively. Defensive injuries in the outfield have also forced reshuffling for the road team, potentially exposing them in a ballpark known for rewarding aggressive baserunning and gap power.

With Seattle’s bullpen nearing full strength and the club boasting a strong home record, the setup leans toward a comfortable win for the hosts. Taking the Mariners at -1.5 offers strong B-grade value—favorable but not foolproof—especially if the Nationals can sneak in a late homer or two. Still, all signs suggest the Mariners are in a prime position to cover the run line, particularly with a rested pitching staff and the benefit of home-field dynamics.
