Mariners Fall 7-4 to Brewers as Kirby Struggles, Rucker Shines
On Thursday night, the Seattle Mariners were defeated 7‑4 by the Milwaukee Brewers at T‑Mobile Park. The loss followed a difficult outing from starter George Kirby, who surrendered six runs in the first inning and was unable to regain control for the rest of the game.
Kirby’s debut began poorly. The Brewers sent 10 batters to the plate in the first inning, scoring six runs on a sequence that included a single, walk, double, single, single, double, double. The pitcher’s exit velocity for the game averaged 99.3 mph, the fifth‑highest for a starting pitcher in 2026. After a one‑out single in the fourth inning, Kirby was removed with the score 6‑0.
The Mariners’ pitching staff has struggled throughout the season. Since the All‑Star break, the team has been dead last in the majors in fWAR and is projected to finish below average for the second consecutive year. The organization’s bullpen has been among the five worst in the league since Rucker joined on June 12.
After Kirby’s exit, José Ferrer finished the fourth inning, and Michael Rucker entered in the fifth. Rucker pitched 2 2/3 innings, striking out four, allowing no hits, and generating six whiffs on 15 swings. He also walked seven of 17 pitches outside the zone. Rucker’s performance was highlighted by a 97‑mph cutter that yielded a called strike, followed by a 97‑mph fastball that produced a swing‑strikeout.
The Brewers’ offense continued to be productive. They walked six times, collected six hits, and hit several hard balls. The Mariners’ offense, meanwhile, managed six hits and six walks but failed to produce the power needed to overcome the Brewers’ early lead. Taylor Ward, acquired at the trade deadline, drew his first two walks in a Mariners uniform.
In the eighth inning, the Mariners’ bullpen was forced to use journeyman Jhonathan Díaz after most of the bullpen had pitched the night before. Díaz surrendered a home run, extending the Brewers’ lead to 7‑4. The final inning saw Julio hit a 111‑mph line drive to centerfield that was fielded by Mitchell, ending the game.
The Mariners finished their recent road trip with a 4‑5 record, including some notable wins amid several difficult losses. They are scheduled to face the Chicago Cubs this weekend and the Philadelphia Phillies early next week. The team’s remaining schedule is considered the easiest in the league.
The Mariners’ season is over, but the team remains competitive in the standings. The loss to Milwaukee underscores ongoing challenges in pitching and offensive production, but the bullpen’s solid work in the middle innings and the offense’s ability to generate hits keep the team within reach of a playoff berth.
The game highlighted the contrast between Kirby’s early struggles and Rucker’s effective relief. While Kirby has historically been a strong starter, his current season has been marked by a decline in strikeouts and an increase in walks. Rucker, on the other hand, has posted an FIP‑ of 81, second best on the active roster after Luis Muñoz.
As the Mariners prepare for their next opponents, the organization will likely focus on improving pitching consistency and bolstering offensive power. The upcoming games against the Cubs and Phillies will be critical in determining whether the team can maintain its position in the American League West.
The Mariners’ performance against Milwaukee demonstrates the importance of early pitching control and offensive execution. While the bullpen performed admirably, the team’s overall struggles in the first inning and lack of power hitting contributed to the loss. The Mariners will need to address these issues as they move forward in the season.
In summary, the Mariners lost 7‑4 to the Brewers, with George Kirby struggling early and Michael Rucker delivering a solid relief outing. The team’s bullpen remains one of the weaker units in the majors, and the Mariners’ offense failed to generate the necessary power. The upcoming games against the Cubs and Phillies will test the team’s resilience and ability to improve.
