Manny Machado's attack of Royals pitcher Yordano Ventura captured everyone's attention Tuesday as it became the biggest story in baseball on an otherwise quiet sports night.
It inspired thousands of tweets and memes, and also memories of O's brawls before.
The Orioles were involved in two of baseball's most famous donnybrooks, both in the 1990s.
Thankfully, low-def YouTube documentation of each exists.
May 19, 1998: Benitez takes frustrations out on Yankees
O's closer Armando Benitez allowed a go-ahead three-run home run to Yankees center fielder Bernie Williams in the eighth inning. Benitez's next pitch drilled Tino Martinez between his shoulder blades.
This ensued...
The brawl lasted 10 minutes, and when the game ended, the last-place Orioles had their sixth straight loss, and 22nd in 32 games.
"You've got a guy on the mound throwing 100 miles per hour," 23-year-old shortstop Derek Jeter said. "That was just dumb from the start."
Benitez insisted he was merely trying to throw inside.
The Yankees didn't buy it. Neither did the league office, which suspended him eight games the next day.
"I've never seen anything like that in 25 years," Yankees owner George Steinbrenner said. "That guy that pitcher should be suspended for the rest of the year. That was a classless act. He's got no class."

Yankees manager Joe Torre: "It was a rotten thing to do. It was so blatant. Benitez caused a riot. That's the downside to the designated hitter. The pitcher gets braver when he doesn't have to face the music."
June 6, 1993: Moose vs. the Mariners
Mariners batter Bill Haselman immediately charged at Orioles pitcher Mike Mussina after "Moose" threw a pitch near Haselman's head in the seventh inning.
Watch Mussina's little deke just as Haselman reaches the mound. Pretty quick feet, but there was no avoiding this melee, which involved 60 men.
Mussina's pitch was retaliation for Mariners hurler Chris Bosio sending two balls behind Orioles batters. Bosio got the worst of this incident, as he rebroke his collarbone in the fight.
The Orioles won 5-2 and Mariners manager Lou Piniella protested because, somehow, umpires didn't eject Mussina.
The incident sparked questions about the role of stadium security. The Camden Yards staff effectively kept fans off the field but did nothing to prevent the players from fighting.
