Describing Didi Gregorius as “really beat up,” Joe Girardi gave the shortstop Monday night off, and might rest him Tuesday, as well.

“He needs a day,” Girardi said.

Girardi said Gregorius, in a 3-for-34 slide going into Monday, has been impacted by the two pitches he took to his left arm twice in a week’s span — Aug. 27 and Sept. 3 — as well as assorted balls he’s fouled off his person.

“Whether it’s being hit in the arm [by pitches], hit in the rib cage from foul balls. ... I think it’s affected him swinging the bat some,” Girardi said. “It’s not that I’m afraid to use him tonight, but I thought a day off, we’ll see how he feels tomorrow. Maybe even a couple of days off might help him.”

Gregorius has been the Yankees’ most consistent offensive performer this season, without a prolonged slump until recently. Still, he entered the week with a .273/.301/.443 slash line, with 17 homers and 64 RBIs.

“Sometimes you just get to a point where you need to shut a guy down for a day or two,” Girardi said.

Rookie Ronald Torreyes replaced Gregorius at short.
