By the bottom of the eighth inning Friday night at Yankee Stadium, both managers were watching the game from the comfort of their respective clubhouses.

Neither Yankees boss Aaron Boone nor Tigers skipper Ron Gardenhire was happy with the umpires as both were ejected in a pair of sequences that may have changed the game — one more definitively than the other in the Yankees’ 7-5 win.

Boone got tossed before even leaving the dugout during Gleyber Torres’ at-bat in the fifth inning, then got his money’s worth.

Boone came racing out of the dugout to stick his face in home plate ump Nic Lentz’s, shouting at him and appearing to bump him with his cap. The rookie manager then squatted down behind home plate and imitated a catcher, clearly perturbed by Lentz’s strike zone.

“I just had some issues with the zone on a couple pitches, key pitches were missed,” Boone said. “I took exception to it. I guess he had heard enough.”

The Yankees were being no-hit at the time by Jordan Zimmerman, but Boone’s act appeared to fire up his team. In the next inning, they crushed three home runs in a span of four batters to take the 4-3 lead.

“He protected us,” Torres said. “He’s the manager. He did his job. We feel proud. After that we were more excited.”

They got a kick out of the animated catcher’s stance, too.

“That was funny,” said Aaron Hicks, who hit one of the homers. “Sometimes stuff like that ignites an offense.”

“I hadn’t stretched tonight, I wanted to make sure I was good and loose,” Boone said with a grin. “It gave my kids something to make fun of me about.”

The call that set Gardenhire off had a more direct result. First base umpire Paul Nauert said Luke Voit checked his swing on a full count with two on and two outs in the bottom of the eighth. The Tigers were up 5-4 and all believed Voit had gone around on Joe Jimenez’s pitch until Nauert signaled otherwise, keeping the inning alive for the Yankees to eventually take the lead.

Gardnehire came out of the dugout and before he could even reach Nauert, he got the hook.

“It looked like [Jimenez] got the last out,” Gardenhire said. “It looked like he did.”

On his way off the field, Gardenhire asked Voit if he swung.

“I don’t know where he’s from, I didn’t understand his language,” Gardenhire said of Voit, a Missouri native. “But he did have a big smile on his face.”
