The Seattle Mariners suffered the worst defeat in franchise history on Tuesday night, falling 22-0 to the Milwaukee Brewers at American Family Field. The historic blowout matched the largest shutout victory in Major League Baseball’s Modern Era and featured a bizarre cascade of late-inning miscues.
Tuesday evening at American Family Field began like any standard mid-summer matchup, but it devolved into a record-breaking catastrophe for visiting Seattle. The 22-run margin eclipsed the previous most lopsided defeat in franchise history, a 21-1 loss to Houston on September 8, 2019. Across the league, the final score tied the largest shutout victory in Major League Baseball’s Modern Era, which dates back to 1900. That historic company includes Pittsburgh’s 22-0 win over the Chicago Cubs in 1975 and Cleveland’s 22-0 victory over the New York Yankees in 2004.
How a Quiet Pitcher’s Duel Unraveled in the Fifth Inning
For the first four innings, Bryce Miller kept them within striking distance despite Milwaukee creating early traffic. The right-hander retired nine straight batters at one point, keeping the deficit at a manageable 1-0.
Then the game collapsed. The Brewers plated five runs in the fifth inning, punctuated by Yelich’s three-run homer with two outs that turned a tight contest into a 6-0 hole. That swing marked Miller’s final batter of the evening.
“If I make a pitch there, get out of it, we’re still in the game. Left the splitter up a little bit, and he got to it. … We get out of that inning and it’s 3-0 instead of 6-0. It’s a big difference.”

Manager Dan Wilson accepted full accountability after the game for leaving his starter in to face the middle of the Milwaukee order in that decisive fifth frame.
“That decision’s on me. Accountability’s there. It’s on me. It starts and stops there. … Wanted to get Bryce through there, but just didn’t make the right choice, and it cost us.”

An Eighth-Inning Collapse and a Baserunning Blunder
Things only deteriorated as the night wore on. David Hamilton hit a three-run home run in the sixth inning, and Jake Bauers added a two-run shot moments later to stretch the lead to 11-0. Milwaukee later added two runs in the seventh before a nightmarish eighth frame.
With the contest already out of reach, Seattle deployed infielder Leo Rivas to pitch the bottom of the eighth. Rivas struggled to find an out, allowing all but one of the first 10 batters to reach base safely as the Brewers poured on nine additional runs.
The offensive onslaught included Luis Lara’s first career major league home run. Amid the eighth-inning chaos, center fielder Julio Rodríguez committed a mental error that perfectly captured the team’s evening.
With the bases loaded and one out, Christian Yelich lifted a routine fly ball to deep center. Rodríguez caught it and casually tossed the sphere into the stands, forgetting there were only two outs. While one runner had tagged from third, the premature souvenir gift allowed a second runner to scamper home from second base, pushing the score to 21-0.
“You obviously never want to be the guy that does that. But it’s a long game, you’re on defense for a while, and it was kind of chaos there in the last inning with the lineup turning over and all the action going. It just happens sometimes. You lose track of the outs.”

A Silent Bats and Historical Context
While Milwaukee piled up 22 runs, the Seattle offense provided zero resistance. The visitors managed just five hits and suffered their 12th shutout loss of the season, even failing to score in the ninth when the Brewers turned to catcher Gary Sánchez to pitch.
The collective performance came just a day after Seattle secured two of three games against Houston, pulling within four games of the Astros in the American League West and sparking hope that a dormant lineup was waking up. Instead, the club was left processing an unprecedented franchise low.
While historic by franchise standards, Tuesday’s final margin still sat well short of Major League Baseball’s all-time worst defeat. That dubious distinction remains held by the 2007 Texas Rangers, who defeated the Baltimore Orioles 30-3.
Looking Ahead to the Next Game
With a quick turnaround on the schedule, players and coaching staff alike emphasized the need to erase the memory of the blowout immediately. The team checked into their hotel looking toward the next contest.

“This was an embarrassing loss. We got our [butts] kicked. At the end of the day. We’ve got to go to the hotel, sleep, wake up, and we’ve got another game tomorrow.”

Catcher Cal Raleigh offered a similar sentiment regarding how the clubhouse plans to handle the historic defeat moving forward.
“Just flush it. Obviously, you don’t ever want to get beaten like that. But at the same time, move on, flush it, go to the next one.”
