BALTIMORE — Manny Machado had no intention of taking a 99 mph fastball in the back without retaliating.
So when the inevitable occurred, the Orioles infielder charged the mound with his fists clenched.
Royals RHP Yordano Ventura hit Machado with a pitch to spark a bench-emptying fray during Baltimore's 9-1 rout Tuesday night.
Ventura drilled Machado just under his No. 13 in the fifth inning as the two-time All-Star turned away. In the second, with Baltimore leading 5-0, the two exchanged words after Ventura twice threw inside pitches.
So before Machado headed to the plate in the fifth, he got a word of warning from manager Buck Showalter.
"I thought he was trying to hit him the at-bat before," Showalter said. "That's why I talked to him before he took his last at-bat. I wanted him to be aware of it."
An instant after the ball hit him, Machado charged. Ventura prepared by slinging aside his cap and glove, but Machado landed a solid punch before the pitcher tackled him.
"I don't regret anything," Machado said. "When somebody's throwing 99 at you, it's going to hurt. You can ruin someone's career."
Both dugouts and bullpens emptied before peace was restored. Machado and Ventura were ejected.
Ventura insisted the pitch was unintentional and implied that Machado has a reputation as a hot head.
