Tim Federowicz: I hope we face Ian Kennedy in the next series

One of baseball’s unwritten rules is not to throw at a pitcher. Especially at his head.

For Diamondbacks starter Ian Kennedy, who’s plunked 41 batters since 2010, it seems that rule doesn’t apply.

Kennedy hit Dodgers pitcher Zack Greinke in the left shoulder with a fastball, inducing a bench-cleaning brawl in the seventh inning of the Dodgers’ 5-3 win Tuesday night.

Greinke was unhurt, but many Dodgers players were left with a bad taste in their mouths.

Catcher Tim Federowicz, whose three-run double in the eighth inning proved the difference, implied that this dispute is not over.

“You hit our guy, we hit yours, that’s the way it should be,” Federowicz said. “But [Kennedy] took it another level, so we’ll see him next time. I hope we face him next time.”

Kennedy was immediately ejected, as was Diamondbacks Manager Kirk Gibson.

Kennedy also tagged Yasiel Puig in the nose in the sixth inning, a play that sparked Greinke to retaliate by hitting Diamondbacks catcher Miguel Montero in the top of the seventh.

“It should’ve been really over at that point,” Dodgers Manager Don Mattingly said.

But it wasn’t. Kennedy pitched to Luis Cruz, getting him to pop out, before cranking a 92-mph two-seamer toward Greinke’s head. Greinke turned away from it, and showed minimal reaction. The rest of his team didn’t.

The Dodgers’ Skip Schumaker, who was on deck at the time, said he’s never seen a pitcher throw at two different batters’ heads in one game. Dumb, he called it. Dangerous.

“It’s different if it’s a beanball war,” Schumaker said. “I’ve been a part of those before. I get it. It’s a part of the game. I liked it. It gets guys going. It gets the fans fired up. I get all that. I love it. But when you start throwing at guys’ heads, it’s a different story.”

When asked if he thought the rage felt throughout the Dodgers locker room would carry over to future games, Jerry Hairston Jr. paused for a moment.

“We’ll see,” he said.
