After Aaron Judge and Gary Sanchez announced that they will compete in the Home Run Derby next Monday, Judge asserted that they will treat the contest like regular batting practice. That should be enough to ensure an eye-popping show.

That is the informed judgment of the people who know best, the Yankees teammates who watch the two players hit balls far beyond fences before every game.

“It’s must-watch TV. Every day,” said Dellin Betances, who also will be among the five (or possibly six) Yankees at the All-Star Game in Miami next week.

During daily batting practice, Betances and fellow pitchers are assigned to roam the outfield and shag fly balls.

“For me, we take turns on what times we shag. Some guys go out for the first half, some guys go out for the second half. I try to make sure I’m always out there for Judge because I’m just trying to see where that ball is going to land,” he said. “That’s what’s going to happen in the Home Run Derby. Everyone is excited. Obviously, this guy is a monster. I think both of those guys are impressive and I think the fans are going to get a fun show to watch.”

Luis Severino, a starting pitcher and another of the Yankees All-Star representatives, said, “I think it’s fun to go shag with them because there are no balls on the field. They’re all in the stands.”

Second baseman Starlin Castro, the other Yankee named to the American League team Sunday, said he will attend the All-Star Game even if his strained right hamstring will not allow him to play. “It’s going to be awesome. I’m going to be on the field, supporting my teammates,” he said, noting that he usually is in the same batting practice group as the two young sluggers.

“I’ve never seen anybody hit the ball like that. I enjoy every single moment those guys hit the ball like a joke,” he said, adding that, like his teammates, he hopes Didi Gregorius gains the final spot in a vote of fans.

Of course, Judge and Sanchez are in the Midsummer Classic because of how they hit during games, not just before them. Judge hit his major-league leading 28th home run Tuesday. Sanchez hit 33 home runs in his first 100 games, tied for second in major league history (behind Mark McGwire).
