The postseason has not changed Didi Gregorius’ fortunes.

The slumping shortstop entered Game 1 of the ALDS on Friday night mired in a 2-for-22 funk and showed no signs of getting out of it in the Yankees’ 10-4 victory in The Bronx.

Aaron Boone went into the game believing the playoff intensity and atmosphere would benefit Gregorius.

“I just feel like he’s one of those guys that the bigger the stage, the brighter the lights, I feel like he thrives in that,’’ the manager said before the game. “I feel like he’s been healthy now for a while and I feel like he’s a guy that [if he] has a good at-bat or two here, I think that’s something that can really propel him moving forward.”

Instead, Gregorius — hitting eighth in the lineup — struck out twice and popped out. He worked a walk and scored in a three-run seventh.

“We got the ‘W’ and that’s all that matters,’’ Gregorius said. “It was not a good day [for me at the plate], but it is what it is.”

And the timing issues that had him searching in the latter stages of the regular season haven’t gone away.

“Some days it’s good, some days not,’’ Gregorius said.

Gregorius had hoped to start these playoffs better than the last one ended, since he suffered a torn UCL nearly a year ago making a throw in a postseason loss to the Red Sox at Fenway Park.

This is Gregorius’ third straight postseason appearance with the Yankees. He has had a fair amount of success in October, but this has been a different kind of season for him.

After missing much of the first half while rehabbing from offseason Tommy John surgery, Gregorius came back in June and showed flashes of his old form, but much of his season has been unproductive.

He has pulled more balls this year than he typically has, so he has been more susceptible to hitting into the shift. Gregorius insisted, however, as the Yankees headed into the postseason, that he was ready to go.

He has recovered from the elbow surgery, but he also has been bothered by a finger injury and then suffered a right shoulder contusion when he was drilled by a Clayton Kershaw pitch against the Dodgers in August.

“I think the biggest thing with Didi is obviously returning in a timely fashion like he was able to do from Tommy John, probably getting back a little earlier than some people expected,’’ Boone said. “[There were] things he was able to play through, but probably kept him from getting on one of those hot streaks that he’s kind of been known for. But I do feel like he’s been healthy now for a while and still feel like his best baseball is ahead of him.”

If that doesn’t happen soon, it may be too late.
