Willson Contreras at the center of benches-clearing scuffle, throws helmet at Nationals pitcher

Absolute bedlam broke loose at Fenway Park Tuesday night.

The Red Sox and Nationals turned a regular June game into the biggest baseball brawl of the season after Boston hothead Willson Contreras completely lost it.

Commissioner Rob Manfred can't hop on the phone fast enough.

It all started in the fourth inning when Nationals right-hander Cade Cavalli punched out a visibly frustrated Contreras and barked at him to "sit down."

Contreras immediately erupted. He charged the mound, and the dugouts and bullpens emptied as the infield turned into a full-blown brawl. Contreras eventually broke free from the sea of players trying to hold him back, reigniting the chaos.

WATCH:

Things hit a boiling point when Contreras leaped into the air and hurled his batting helmet directly at Cavalli.

The umpires issued a flurry of ejections. Contreras was tossed immediately, while Red Sox outfielder Nate Eaton, interim manager Chad Tracy and Washington pitcher Miles Mikolas were all sent to the showers early.

Tuesday night's explosion from Contreras had actually been 24 hours in the making.

On Monday night, Contreras was ejected in the second inning after a check-swing strikeout prompted him to give a sarcastic ABS challenge gesture at the umpire, earning an instant boot. Earlier that day, Contreras had broken down in tears while talking about the deadly earthquakes that devastated his native Venezuela.

By getting ejected on consecutive nights, the 34-year-old capped one of the wildest 48-hour stretches of his career.

But MLB isn't exactly in the empathy business.

When you turn your batting helmet into a weapon, the suspension hammer is coming regardless.
