Jasson Dominguez isn’t slowing down. 

The rookie hit the fourth homer of his young career on Friday night, the lone highlight in the Yankees’ 8-2 loss to the Brewers at the Stadium. 

The two-run shot traveled an estimated 402 feet and gave the Yankees an early and short-lived lead over Milwaukee. 

Dominguez, 20, became just the second player in franchise history to hit at least four homers in his first seven games, joining his manager at Triple-A Scranton/Wilkes-Barre, Shelley Duncan, who did it in 2007. 

All four of his home runs have come from the left side.

He later added his first stolen base. 

Dominguez, who was signed by the Yankees out of the Dominican Republic at the age of 16 for $5.1 million in 2019, has spent a full week in the majors and has been held hitless just once. 

“He’s got good strike zone recognition and really comfortable at-bats,’’ manager Aaron Boone said. “That’s who he is. It’s one of the things that gets you excited [about him].” 

Teams and pitchers are in the process of figuring out how to deal with Dominguez, but Boone said he feels organizations already had a pretty good idea of what the rookie’s strengths and weaknesses were before he made it to the majors. 

“With the information available now — and video — right away, from his debut in Houston, I’m sure Houston had an idea of who he was and how to approach and attack him,” Boone said before the game. “But you are gathering information at the big league level to create game plans now. There’s tinkering done by opposing teams and a lot of this game is how you make adjustments back now.” 

So far, the evidence shows the switch-hitting Dominguez is stronger from the left side against right-handed pitchers than from the other side of the plate. 

After the game Friday, in which Dominguez hit third in the lineup for a sixth straight game after hitting fifth in his debut, he was 7-for-22 with four homers as a lefty and 1-for-5 from the right side.

Dominguez has consistently hit better as a lefty throughout his minor league career and had an .846 OPS from the left side this year, with a .725 OPS from the right. 

He already has made an impression not just on Boone, but on his new teammates. 

DJ LeMahieu, for one, hasn’t been surprised to see Dominguez hitting in the heart of the lineup, despite his inexperience. 

“He’s gonna be a really good player in this league and it seems like he’s a middle of the lineup kind of guy,’’ LeMahieu said. “There’s hype around him for a reason. We’ve seen in a few games how much talent he has and I’m excited to see what he can do in this game. He’s a special talent.” 

Boone said he had no hesitance having Dominguez hit in the meat of the order.

He also acknowledged that this is not a typical Yankees offense, with injuries and their place in the standings altering the dynamic significantly. 

“I just think he’s a really good player and I wanted him up there,” Boone said. “When I have an opportunity against certain pitchers, I crave that balance if we can get it.” 

On Friday against Milwaukee right-hander Colin Rea, for instance, Boone started three lefty hitters, with Dominguez batting third, fellow rookie Austin Wells fifth and Jake Bauers eighth. 

“It’s made a lot of sense to have him in that slot and he’s been very productive there,” Boone said. 

That’s especially true when you consider the Yankees have seven rookie position players, due to roster moves and injuries. 

Dominguez has also struck out just five times in 29 plate appearances, although that’s coupled with just two walks. 

While this is hardly where the Yankees thought they’d be at the beginning of the season, Boone said he’s enjoying seeing the start of Dominguez’s career. 

“It’s been fun to see the start of a major league journey,” Boone said.
