PITTSBURGH — Yankees reliever Anthony Misiewicz was drilled in the head by a 100.6-mph line drive in a scary scene on Friday night at PNC Park.

The scorching liner, off the bat of the Pirates’ Ji Hwan Bae, ricocheted off the left side of Misiewicz’s face and ended up in right field as the stadium quickly fell silent.

Misiewicz crumpled to the ground, but remained alert as trainers quickly tended to him. After a few minutes, he got to his feet, with a towel over the left side of his face, and sat down on a cart that took him off the field.

The 28-year-old was assessed by Pirates team doctors before he was transported to Allegheny General Hospital for further testing.

Shortly after the Yankees finished off a 7-5 win, manager Aaron Boone said that Misiewicz had just gotten done with some scans, but the results were not immediately known.

“All I know is he left here in good spirits and [the medical staff] felt like in a pretty good spot,” Boone said. “Just hoping and praying for the best as far as results and the hours after.”

As Misiewicz was down on the ground, the Yankees’ infielders took knees around him and Aaron Judge, who fielded the ricochet in right field, also came in to check on him.

On his way off the field, Misiewicz was talking with infielders and exchanging high fives and fist bumps, with Anthony Volpe even handing him the ball that inflicted the damage.

The Yankees also got some peace of mind because Misiewicz was coherent and even joking around with them as he left the field.

“He kind of dropped, ‘I thought I threw a pretty good curveball there,’ ” Judge said. “Hearing him joke at least helped us reassure he was going to be all right.”

Still, the seconds after the play happened were frightening.

“Right away, kind of that deafening silence, that pit in your stomach,” Boone said.

“Just sick to my stomach about it,” added Gerrit Cole, who was on the trainer’s table when it happened before he rushed back to the dugout. “Just the fact that he’s alert through pretty much the whole thing, which is probably not a whole lot of fun to be alert through, but it’s better than the other way. We’re just thinking about him.”

Misiewicz was making his third appearance with the Yankees after being called up from Triple-A last Sunday. The lefty tried to get his glove out to deflect the line drive, but could not. He had barely any time to react.

“I was looking at him and I didn’t really know where the ball went and all of a sudden I saw something flying all the way out to me,” Judge said. “I’ve never seen anything like that before. Hopefully we get some good news here soon.”
