Prediction Washington Nationals vs Seattle Mariners 05.28.25

Tonight’s matchup at T-Mobile Park pits the Washington Nationals (24-29) against the Seattle Mariners (29-23) in a game slated for 9:40 PM. The Mariners, currently holding a winning record, will be looking to extend their lead in the division, while the Nationals aim for an upset on the road. This should be a compelling contest between two teams with contrasting strengths and weaknesses.

The Nats are struggling offensively, boasting a league-average batting average of just .241 (19th in the league). Their 4.25 runs/game is a clear indication of their offensive woes. Their pitching staff has been a major liability, carrying a bloated 5.07 ERA. They’re only averaging 7.96 hits per game, further highlighting their offensive struggles. They need a breakout performance at the plate to have any chance in this one.

The Mariners, while not exactly lighting the world on fire offensively, are slightly better than the Nats, with a .237 batting average (21st). Their pitching staff, however, is a significant strength, posting a respectable 3.69 ERA. Their bullpen has been solid, racking up 18 saves. They’re averaging 8.04 hits per game and scoring 4.58 runs/game, showing a slightly more potent offense than their opponents.

This pitching matchup is fascinating. For the Nationals, T. Williams (2-5, ERA 6.39) takes the mound, carrying a significant weight of poor performance. Facing him is G. Kirby (0-1, ERA 12.27) for the Mariners, whose ERA is alarmingly high, suggesting he’s had a rough start to the season. While Kirby’s ERA is drastically worse, it’s a small sample size and the potential for a bounce-back game exists. However, given Williams’ consistent struggles, the Mariners’ pitching appears to hold the advantage, even with Kirby’s recent performance.

Prediction: Seattle Mariners. Despite Kirby’s high ERA, the Mariners’ superior pitching staff and slightly better offense give them the edge. The predicted total runs scored is over 8.5. While both offenses are subpar, the potential for a high-scoring game exists, given the pitching matchups and the Mariners’ home-field advantage.
