Brett Gardner was scratched from Sunday’s lineup with a sore left knee, according to Aaron Boone, adding to the injury issues the Yankees have faced throughout the season — especially with their outfielders.

Boone expected Gardner to be available Sunday and that the soreness was the product of wear and tear. He was replaced in the lineup by Mike Tauchman.

Cameron Maybin (strained left calf) is nearer to a return. Provided he doesn’t suffer a setback, he’ll start a rehab stint with Triple-A Scranton/Wilkes-Barre on Tuesday in Columbus.

Giancarlo Stanton, though, is not close to getting back from his quad injury.

“It’s better, but still slow,’’ Aaron Boone said of Stanton’s recovery. “He’s not doing baseball activities yet. He continues to work on stabilizing things to get the quad built up and strong.”

Stanton has played just nine games this season, bothered by biceps, shoulder and quad injuries.

“It’s moving slow, but in talking to him, he feels like he’s making progress,’’ Boone said. “The first couple of weeks were a little frustrating.’’
