Brewers Rout Mariners 22-0, Tie MLB Shutout Record at American Family Field

On Tuesday, August 18, 2026, the Milwaukee Brewers demolished the Seattle Mariners 22-0 at American Family Field, tying baseball’s modern-era record for the largest shutout margin and matching the franchise’s single-game runs record. Four Brewers homers — including a first career blast from Luis Lara — and a five-hit shutout from the pitching staff turned a midweek series opener into one of the most lopsided nights in MLB history.

The major league-best Brewers (78-48) scored in six separate innings, piled 22 hits with zero errors, and held Seattle to five hits and four errors. For the Mariners (59-67), the defeat was the worst in franchise history — worse than a 21-1 loss to Houston in 2019 and a 15-0 shutout against Minnesota in 1977.

How the runs piled up

Milwaukee’s scoring by inning: 1-0-0-0-5-5-2-9 — the game ended after eight Brewers runs with Seattle still scoreless in the ninth.

Inning	Key moment	Score
1st	Jake Bauers doubled; William Contreras singled; Bauers scored after Cal Raleigh dropped the ball on a chaotic slide	1-0
5th	Christian Yelich three-run homer (his 8th of the season)	6-0
6th	David Hamilton three-run HR; Bauers two-run HR (22nd of season)	11-0
7th	Two more runs extended the cushion	13-0
8th	Nine runs off position player Leo Rivas, including Lara’s first career homer; Julio Rodríguez threw into the stands after catching a flyout, forgetting the inning was not over	22-0

Bauers opened the scoring in unusual fashion: Randy Arozarena’s throw from left beat him to the plate, but Raleigh’s mitt contact dropped the ball and Bauers dove back safely. From there, the Brewers never looked back.

Standout performances

Player	Line / moment
Garrett Mitchell	4 hits in the rout
David Hamilton	3-for-5, 4 RBI, 3-run HR — career-high RBIs
Christian Yelich	2-for-5, 4 RBI, 3-run HR
Luis Lara	3-for-6, 4 RBI, first career home run
Jake Bauers	2-for-3, 2 RBI, HR; scored the first run
Kyle Harrison	5 IP, 2 H, 2 BB, 8 SO — rebound after 8 runs in his previous start
Gary Sánchez	Pitched the 9th, completed the five-hitter; worked around two hits

Shane Drohan worked two innings in relief, and Grant Anderson handled the eighth before Sánchez — normally a catcher — closed out the shutout, at one point throwing pitches under 40 mph according to game accounts.

Seattle’s lineup managed little against Harrison. Dominic Canzone and Josh Naylor each singled; the Mariners stranded runners and committed four defensive miscues that fed Milwaukee’s attack.

The record books

Since 1901, only three MLB games have ended 22-0 in the modern era:

Date	Winner	Loser
Sept. 16, 1975	Pittsburgh Pirates	Chicago Cubs
Aug. 31, 2004	Cleveland Indians	New York Yankees
Aug. 18, 2026	Milwaukee Brewers	Seattle Mariners

Milwaukee also matched its own franchise record for runs in a single game. The margin tied the modern shutout record; no team since 1901 has won a shutout by more than 22 runs.

For Seattle, the 22-run deficit set a new franchise record for the largest loss. Cal Raleigh was pulled during the eighth-inning avalanche as the game slipped beyond recovery, and Rodríguez’s late miscue added to a night Seattle will want to forget.

What it means for both clubs

The Brewers continue to lead the National League with the best record in baseball, reinforcing their status as a legitimate 2026 World Series contender. A night like this — balanced offense, dominant starting pitching, and even a catcher finishing a shutout — underscores the depth of a roster that has been clicking for months.

Seattle arrived in Milwaukee hoping to stabilize a season that has fallen short of preseason expectations around the AL West race. Instead, the Mariners absorbed a historic humiliation that will dominate highlight reels and record lists for years. Logan Gilbert (9-7) is scheduled to face Dustin May (6-7) in Game 2 on Wednesday, giving Seattle an immediate chance to reset.

Discussion

A 22-0 shutout is rare enough that most fans never see one in person — Milwaukee and Seattle produced the third in more than a century of modern baseball.

1. Kyle Harrison bounced back with five shutout innings after allowing eight runs in his previous start. Does one dominant outing against a struggling lineup prove he is a reliable October arm, or was this more about Seattle’s cold bats than Harrison’s turnaround?

2. Seattle used position player Leo Rivas in the eighth as the margin grew. Is deploying a non-pitcher in a blowout fair roster management, or does it risk turning an already brutal night into a franchise-record embarrassment?

3. The Brewers are on pace for the best record in MLB. After a 22-run statement win, are they the clear National League favorite — or does Milwaukee still need to prove itself against top-tier pitching in a playoff setting?

Where do you rank this game among the wildest MLB blowouts you have seen — and can the Mariners recover momentum before the series ends?
