NEW YORK — In an empty Yankee Stadium, Aroldis Chapman cleared the first hurdle of his comeback from left Achilles tendonitis.

“I felt pretty good there, no discomfort at all,” the southpaw said through an interpreter on Tuesday afternoon, after his first mounding session since coming on the disabled list on 24 may.

Since then, the dynamics of the Yankees bullpen have changed.

Chad Green underwent Tommy John surgery at the end of the season and fellow right-hander Jonathan Loaisiga landed on the IL, due to shoulder inflammation.

And right-hander Clay Holmes hadn’t given up a run in his last 26 appearances (28 innings), converting five saves on five chances as the Yanks closed in.

Manager Aaron Boone has only committed to Chapman being a high-leverage late-inning arm when he returns to the Yankees bullpen, given the success of Holmes — forged by a devastating lead.

“It’s good to see him back there,” Boone said after watching part of Chapman’s session on the main pitch under the supervision of pitching coach Matt Blake. “He looks good, he looks healthy.”

Treat discomfort

If there’s drama about changing roles in the bullpen, well, it’s a problem down the road.

Right now, Chapman and the Yankees are focused on the closer veteran’s next step, which is another bullpen session followed by an outing against live hitters.

“Once we get through that, we’ll see where we are,” said Chapman, who isn’t sure if he would need a minor league rehab assignment.

Chapman, 34, remained a bit vague about how the Achilles problem might have affected his most recent performance, when his command suffered.

In his last five appearances, Chapman has driven in six earned runs in 3.2 innings, with nine hits – including two home runs – three walks and four strikeouts.

During this period, the opponents beat .474 against Chapman, with an OPS of 1.469.

“You have to deal with things like that sometimes,” Chapman said of the discomfort. “It’s your job to compete. You have to toughen up and do the best you can.

“(I) am moving forward and looking to get back into that.”

Boost from the bullpen

In the Yankees’ first 60 games, Boone received saves from six different relievers, Holmes and Chapman each 9-for-9 in save chances.

In his free agent season, Chapman is in the final year of a three-year, $48 million deal, and is unlikely to return to scratch in 2023.

Before the Aug. 2 trade deadline, the Yankees may be looking for another reliever — preferably a left-hander.

But they have potential bullpen candidates in their system, including southpaws Ken Waldichuk and JP Sears, and veteran right-hander Shane Greene.

Meanwhile, Loaisiga returned to pitching earlier this week and Domingo German (right shoulder injury) is set to begin a minor league rehab mission.

The German, who is yet to pitch this season, is scheduled to pitch a three-inning mock game against live hitters Wednesday in Tampa, Fla.

Boone acknowledged there was a possibility of the German being built as a starter, but that plan has yet to be floated.
