Toronto Blue Jays rookie Alek Manoah has been suspended five games and fined for throwing at the Baltimore Orioles' Maikel Franco on Saturday.
The pitch triggered a benches-clearing altercation.
Manoah was ejected from Saturday's game for hitting Franco after surrendering back-to-back home runs in the fourth inning.
"I tried to get that fastball in, and it slipped away," Manoah said. "I was confused by his reaction. I was questioning, 'What's going on? What's wrong?' Those were my hand gestures as I was walking toward him. I didn't understand the frustration there."
Manoah will appeal the suspension.
