Kansas City right-hander Yordano Ventura hit Manny Machado with a pitch to spark a bench-emptying fray , and the Baltimore Orioles extended the Royals’ losing streak to a season-high six games with a 9-1 rout Tuesday night.

Mark Trumbo homered and drove in four runs, and the Orioles also got long balls from Ryan Flaherty, Chris Davis and Adam Jones.

But the game’s most striking moment came in the fifth, when Ventura (4-4) drilled Machado in the back with a 99 mph fastball. In the second inning, with Baltimore leading 5-0, the two exchanged words after Ventura twice threw inside to the two-time All-Star.

So in the fifth, an instant after the ball hit him, Machado charged the mound. Ventura prepared for the onslaught by slinging aside his cap and glove, but Machado landed a solid punch before the pitcher tackled him to the ground.

Both dugouts and bullpens emptied before peace was restored. Machado was restrained by teammate Chris Tillman after the initial thrust.

Machado and Ventura were ejected with the score 5-1.
