KANSAS CITY, Mo. — Brett Lawrie’s hard slide into second base in the seventh inning Friday was still the primary topic of conversation before Saturday’s game at Kauffman Stadium — and then Lawrie was drilled by a 99 mph fastball from Kansas City starter Yordano Ventura in the fourth inning.

Ventura was ejected immediately, both benches and bullpens emptied with no punches thrown for the second night in a row, and the A’s beat Kansas City 5-0. Josh Reddick had the big blow, a three-run homer that was his first of the year, just before Lawrie stepped to the plate.

Afterward, Reddick was seething about Lawrie getting drilled.

“It’s bush league. There’s no need for that,” Reddick said. “I don’t think it was professional at all. It’s a joke.”

Lawrie was the calmest man on the field, though he was smoked on the elbow and doesn’t wear an elbow pad. He took his base, with Ventura in pursuit until catcher Salvador Perez dragged Ventura away.

“It’s one of those things, if I go and try to make something ridiculous out of it and all of a sudden, we have a huge fight and we have five guys thrown out of the game, three guys hurt, it just causes something I don’t think is needed,” Lawrie said.

The previous night, Kansas City shortstop Alcides Escobar was hurt when Lawrie went hard into him. Escobar was not in the lineup Saturday because of a mild left knee sprain, though he said that he wanted to play.

The specifics of the slide were still under discussion, with Escobar saying, “In that situation, that’s a dirty play. In a double-play situation, you slide hard. In that situation, you slide a little more easy.”

Lawrie said he believed the double play was a possibility because the ball, hit by Reddick, was driven hard up the middle before being deflected toward third. Mike Moustakas flipped it to Escobar.

“I’m running. I can’t see the whole play,” Lawrie said. “For him to say it wasn’t a double-play ball — well, maybe it wasn’t. But I don’t know that.”

A’s manager Bob Melvin agreed, calling the play “a perfect storm” for a potential injury. “You have a guy who’s fast and there’s a little bit of indecision on what’s happening,” Melvin said.

Then there was conflicting information about an apology. Lawrie said he texted one to Escobar on Friday night after getting Escobar’s number from Kansas City first baseman Eric Hosmer. Escobar said that he didn’t receive an apology, so Lawrie showed his text to a reporter and to an A’s public-relations person along with the response from a person Lawrie presumed to be Escobar.

Lawrie said in his message, in part, “Escobar, this is Brett Lawrie, man. I would never ever try to intentionally hurt you or anyone, man. I feel bad about it. … I hope you’re OK.”

He got back a text that said, in Spanish, “That’s stupid, it’s obvious that was intentional.”

When asked for clarification from Royals PR director Mike Swanson, Escobar reiterated that he hadn’t heard from Lawrie and showed Swanson his phone.

Lawrie remained convinced that he had the correct number, “unless Hosmer gave the wrong number, which he wouldn’t do,” said Lawrie, noting that the response didn’t indicate it was a wrong number. “If we were to stand next to each other and I call his cell phone and it rings in his pocket, I’m pretty sure that I’m telling the truth.”
