The Seattle Mariners endured their most lopsided loss in franchise history on Tuesday, falling to the Milwaukee Brewers 22-0. The defeat also marked the largest margin of shutout in Major League Baseball since 1887.

The lopsided score was compounded by a rare miscue from star center fielder Julio Rodríguez in the bottom of the eighth inning. With the bases loaded and the Mariners already trailing significantly, position player Leo Rivas was on the mound for the Brewers. Christian Yelich hit a line drive that Rodríguez appeared to catch for what should have been the second out. However, Rodríguez, seemingly unaware of the out count, tossed the ball into the stands. This action resulted in a dead ball and allowed two runners to advance two bases.

Jonathan Ornelas scored on the error, and William Contreras advanced to third. Contreras then scored on the next play when Luis Lara singled to center, capping the Brewers' scoring.

"You obviously never want to be the guy that does that," Yelich commented after the game. "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."

The 22-0 final is the largest margin of defeat in an MLB game since the Toronto Blue Jays defeated the Boston Red Sox 28-5 in 2023. It also surpasses the Mariners' previous worst defeat, a 21-1 loss to the Houston Astros in 2019.

This 22-0 score ties for the largest margin in an MLB shutout since 1887, when the Philadelphia Quakers beat the Indianapolis Hoosiers 24-0. Prior to Tuesday's game, this margin had only been matched twice since then: in 1975 when the Pittsburgh Pirates defeated the Chicago Cubs, and in 2004 when the Cleveland Indians shut out the New York Yankees by the same score.

Mariners manager Dan Wilson acknowledged the difficulty of the game. "Obviously, not how we wanted to start this game," Wilson said. "It just got out of hand. They put up a lot of runs tonight, and we were quiet offensively. It's a tough one to even think about."

Despite the historic loss, the Mariners remain three games back of a playoff spot with a 59-67 record.
