The Yankees made another splash in the international market Monday, agreeing to deals with several prospects — including Luis Severino’s brother.

Rafael Severino, a 19-year-old right-hander, is at the team’s academy in the Dominican Republic and the Yankees’ current ace was able to give him the news.

“He was freaking out,’’ Severino said of his brother’s reaction to the phone call.

“His fastball is 88-89 [mph], has a good slider and changeup,’’ Severino said when asked for a scouting report. “I went to see him pitch. He’s smart. He doesn’t throw that hard, but he’s really skinny. When he gets stronger, he’s gonna throw hard.”

“It’s definitely good to have another Severino in the mix,” Aaron Boone said.

While Rafael Severino has the recognizable name, the Yankees also signed several higher-profile prospects Monday.

After drafting catchers with their first two picks last month, they added two more Monday. Antonio Gomez signed a $600,000 contract and they also picked up Agustin Ramirez.

They also agreed to deals with two Cuban right-handers, Osiel Rodriguez and Denny Larrondo. Rodriguez, 16, signed for nearly $1 million, according to Baseball America.

Another name to watch is OF Kevin Alcantara, who is expected to fetch a roughly $1 million bonus when he turns 16 this month.

Gleyber Torres had the first three-hit game of his career, but it didn’t end well. His error on Nick Markakis’ grounder to start the 11th led to the winning run. Unlike some of his errors after he was first called up, though, Boone didn’t place the blame on the rookie.

“Just the skip out there [on the grass],’’ Boone said. “It’s gonna happen every now and then. I think some of his errors early were maybe the result of him being new at second, not finishing the play. I don’t think that was the case there. It was a little in-between hop and he couldn’t find the ball right away.”

Masahiro Tanaka (strained hamstrings) will make a rehab start with Triple-A Scranton/Wilkes-Barre on Wednesday with the hope of rejoining the rotation for his following turn against the Orioles.

“I feel great,’’ Tanaka said in English after throwing a bullpen Monday in The Bronx. “I’m ready to go.’’

The Yankees considered starting him against Atlanta on Tuesday after his 48-pitch simulated game in Tampa last week, but opted to build him up.

“I’m absolutely ready to go if they give me the ball for Baltimore,’’ Tanaka said through an interpreter. “I could have pitched in a major league game Wednesday.”

Austin Romine was held out of the starting lineup for a second straight game after suffering a cramp in his left leg in Saturday’s game, but he entered as a defensive replacement in the top of the ninth after Neil Walker hit for Kyle Higashioka in the eighth and finished the 5-3, 11-inning loss behind the plate.

“We thought holding him back another day was probably the smart thing to do,’’ Boone said. “Especially with Gary [Sanchez] down, our depth has taken a hit and Romine is going to be really important the next couple of weeks.”

Sanchez is not expected back from his strained right groin until sometime around the All-Star break.

Miguel Andujar was named AL Rookie of the Month for June, a month after Torres won the award in May. Andujar had seven homers and an OPS of .863 in June. … The Yankees did not have batting practice before Monday’s game. Boone cited the fact that it was over 90 degrees again and the Yankees didn’t finish Sunday’s win over the Red Sox until late.
