TAMPA — Aaron Boone said he believes Gary Sanchez’s defense behind the plate has gotten better, but there continues to be work to be done.

“There’s still a lot of meat on that bone,’’ the Yankees’ manager said Wednesday.

Sanchez is working with new catching coordinator Tanner Swanson.

“He’s improved, I feel like, a lot over the last couple of years, and we feel like with Tanner coming in and the work they’ve already begun, like there’s more there to be had,’’ Boone said. “I’m confident we’ll see the results as the season unfolds.”

Sanchez’s defense has been a topic of conversation since he’s been in the majors. He said Wednesday, when pitchers and catchers reported to camp, that he and Swanson have worked on getting his right knee lower so that he can receive pitches in that position.

“It’s a little hard, because this is something new that you have to adjust to,’’ Sanchez said through an interpreter. “I think we’ve have about a week since we started working together, and I can tell you that now I feel much better than Day 1. It’s a learning process and any time you try something new, you need time to make that adjustment.”

Sanchez was bothered by lower-body injuries last season that limited him to 106 games, though he hit a career-high 34 homers.

This offseason, Sanchez said he focused on becoming more flexible, and that will continue with the Yankees’ new training and conditioning staff that was brought in after the roster was ravaged by injuries in 2019.

“I’ve been working together with the new staff for about a week now and we’ve got to keep doing that and see how it pays off as the season is here,’’ Sanchez said.
