Washington Nationals @ Seattle Mariners - May 28, 2025

As I look ahead to the matchup between the Washington Nationals and Seattle Mariners at T-Mobile Park, it’s hard not to be intrigued by the contrasting trends each team has been displaying recently. The Mariners are coming off a resounding 9-1 victory against the Nationals in their last outing, which not only showcased their offensive prowess but also raised questions about the effectiveness of Washington’s pitching staff.

On Wednesday night, Trevor Williams will take the mound for the Nationals. His season record stands at 2-5 with an ERA of 6.4, which suggests he has struggled significantly this year. Despite averaging just over eight strikeouts per game, his inconsistency has led to a number of poor outings that have hurt his team’s chances. In fact, when we dive deeper into his numbers, it’s clear that he allows more runs than he can mitigate through strikeouts.

Conversely, George Kirby will be on the hill for Seattle. Although his win-loss record is currently 0-1 and his ERA sits at a concerning 12.3, these statistics may not tell the whole story about his potential as a pitcher. With an average of over eight strikeouts per game as well, there’s evidence that Kirby can miss bats; however, he must find a way to limit damage and keep runners from crossing home plate.

When analyzing both teams’ batting statistics per game this season, it appears that Seattle holds a slight edge offensively with an average of 4.6 runs scored compared to Washington’s 4.2 runs per game. Moreover, while both teams have similar batting averages hovering around .230-.236 and comparable on-base percentages (Seattle at approximately 70.6% vs Washington at about 67.8%), what stands out is how effectively each team capitalizes on scoring opportunities.

The Mariners’ recent form shows they’ve been able to generate runs even in tough situations—evident from their recent performance against Washington where they scored nine times despite some struggles earlier in the season (2-5 SU in last seven home games). Meanwhile, Washington’s offense hasn’t been nearly as effective lately; they’ve managed just four RBIs per game on average.

From a betting perspective, oddsmakers opened with Seattle as -180 favorites—a line that reflects confidence in their ability to win this matchup given their recent success against Washington and overall better performance metrics this season.

Given all these factors combined—Williams’ shaky start for Washington coupled with Kirby’s potential upside—and considering both offenses have shown enough firepower lately (particularly Seattle), my prediction leans towards another Mariners victory tonight with total runs likely exceeding the set line of eight based on how both teams have performed recently.

In summary: expect Seattle to capitalize on home-field advantage while taking down Washington once again; anticipate an OVER outcome as both offenses should produce enough fireworks to surpass expectations tonight!
