Injuries continued to mount for the Yankees on Tuesday, beginning when closer Aroldis Chapman was placed on the 15-day injured list with left Achilles tendinitis.

DJ LeMahieu also was a late scratch before the Yankees’ 7-6, 11-inning win over the Orioles with what the team termed left wrist discomfort. And Giancarlo Stanton will undergo an MRI exam Wednesday after he exited the game in the seventh inning with right calf tightness.

LeMahieu received a cortisone shot Tuesday after an MRI exam came back clean, and manager Aaron Boone said “hopefully he’s back, if not [Wednesday], then the next day.”

“Hopefully we dodged something there,” Boone added.

Chapman, meanwhile, has allowed at least one run in each of his past five appearances, the longest stretch of his career, after opening the season with a 12-game scoreless streak. That season-opening streak, however, included seven walks in 10 ²/₃ innings.

He gave up a game-tying home run to A.J, Pollock and another run in the ninth inning of the first game of a doubleheader sweep Sunday by the White Sox. That brought his totals in his past five appearances to six earned runs on nine hits and three walks in 3 ²/₃ innings. His ERA had risen to 3.86, with a WHIP of 1.64.

Before the announcement was made, Boone had said that “Chappy is doing a little better,” but it was “likely” that he’d be shut down.

Setup man Chad Green also is out for the season after it was learned over the weekend that he will require Tommy John surgery on his right elbow. 

Clay Holmes, who has four saves and a 0.42 ERA in 20 relief appearances this season, presumably will take over the closer role in Chapman’s absence. He pitched a 1-2-3 eighth inning Tuesday night.

Kyle Higashioka was reinstated from the COVID-19 injury list, but Joey Gallo and Josh Donaldson remain sidelined.

Higashioka did not play Tuesday, as Jose Trevino, who homered and drove in three runs, including the tying run in the seventh inning and the winning run in the 11th, played the entire game at catcher.

Boone said Higashioka, Gallo and Donaldson have continued to test negative.

“Joey and Higgy are both here and doing well and went through some workouts. … I think they’re out of the woods illness-wise,” Boone said. “Josh is still under the weather. He had a fever overnight, and other symptoms still this morning. So we had him stay home. Hopefully it’s similar to Joey and Higgy and he’s just a day or so behind them.”
