HOUSTON — The hype surrounding Jasson Dominguez was already grand enough when he arrived in the big leagues on Friday.

Then he took a swing.

On the second pitch he saw in his first career plate appearance, the 20-year-old Dominguez belted a two-run home run off future Hall-of-Famer Justin Verlander, a fitting first impression given the lofty expectations that preceded the ballyhooed prospect.

“That’s the way to announce your presence with authority,” manager Aaron Boone said.

Verlander threw a 94 mph fastball in the strike zone and Dominguez, hitting from the left side, crushed it 360 feet the other way into the Crawford Boxes in left field.

It gave the Yankees a 3-0 lead in the first inning on the way to a 6-2 win over the Astros on Friday night at Minute Maid Park. 

“I knew it was going to be a lot of different feelings, finally stepping on the field … my dream coming true right in front of me,” Dominguez said through an interpreter. “I was able to connect for that hit and it ended up being a homer, so my mind was flying away.”

Dominguez, who made his Triple-A debut just 10 days before his MLB debut, became the first Yankee to hit a home run in his first career plate appearance since Aaron Judge in 2016.

“Impressive,” Judge said. “Especially coming here, loud ballpark, facing a future Hall-of-Famer. For him to go up there and do that on the first swing he takes in the majors leagues, it was amazing.”

Dominguez finished the night 1-for-4 with three balls hit at 97.9 mph or harder.

If he was nervous, he did not show it, though those who have played with him previously say he is not fazed by anything.

The hype around Dominguez has been out of control since he signed for $5.1 million out of the Dominican Republic in 2019, but not even Dominguez fully expected to make his MLB debut by the age of 20.

“I didn’t think I was going to get here so fast,” Dominguez said before batting fifth and starting in center field. “Very happy though.”

Had the Yankees’ season gone according to plan, Dominguez likely would have topped out at Triple-A Scranton/Wilkes-Barre this year.

But with the playoffs being a pipe dream as the calendar flipped to September, the Yankees decided to get a head start on evaluating their future, with catcher Austin Wells joining Dominguez in making their big league debuts Friday.

It was only one game, but both prospects looked the part right away, especially with Dominguez going deep in his first at-bat while becoming the youngest Yankee to play in a game since Jose Rijo in 1984.

“For him to go up there and his first swing, first ball he puts in play is a driven ball to the opposite field, that’s impressive,” Judge said. “Sometimes you see guys come up there and they’re a little anxious or a little eager so they’re pulling off the ball, trying to hit it as hard as they can. He just seems cool, calm and collected in the box. To see that out of a rookie, let alone at 20 years old, that’s pretty impressive.”

Across the final month of the season, with the pressure turned down, Dominguez will be the Yankees’ regular center fielder as he gains valuable experience and in turn the organization begins to learn more about their treasured prospect.

Though the sky-high expectations surrounding Dominguez since he signed — putting him in the same sentence with current and future Hall of Famers — were unfair to the player, the Yankees believe Dominguez has handled them all well.

They see an easygoing kid who is liked by his teammates and keeps a steady demeanor regardless of what is happening on the field.

“I think he’s going to be a really good player,” Boone said. “Again, not a finished product. We’ll see how his journey goes. He’s obviously a very young man, super talented. I think when we look up in several years, we’re going to see a really good player in front of us. He gets to start to write that script — in the big leagues anyways — today. We’ll see how it goes and see how that development and journey goes. But I think he has a chance to be a very good player.”
