Backup center Day’Ron Sharpe had registered two double-doubles in each of his first two seasons with the Nets, but the former first-round draft pick already has three in the first quarter of his third NBA campaign.

Brooklyn coach Jacque Vaughn believes Sharpe has heeded his preseason challenge to improve his “professionalism and consistency” and “knowing what I am going to get from him on a nightly basis.”

The 22-year-old big man has “really answered that,” Vaughn added following Sharpe’s latest contribution off the bench — a season-high 15 points with 11 rebounds in Friday’s blowout win over the Wizards.

“I think it is understanding that it affects his playing time. So that’s the biggest weapon right there,” Vaughn said after the Nets improved to 12-9 this season with their sixth win in seven games. “And I think he is realizing that he has a part of this thing and he’s played his part.”

Sharpe’s effectiveness behind starter Nic Claxton has been a key aspect not to be overlooked in Brooklyn’s recent surge.

Claxton contributed 13 points and a season-best 15 boards against Washington, marking the first time this season that both centers recorded double-doubles in the same game.

Afterward, Sharpe called himself “a dog on the glass” and boasted that “nobody can really stop me” on the boards.

“Me and Nic have been together for the last three years. So we got that chemistry together,” said Sharpe, the 29th-overall pick out of North Carolina in 2021. “Some things he sees out there, he’s telling me I need to do, I’m listening. Some things I see when I’m on the sidelines, he’s like, ‘I got you.’ We complement each other just like that.

“But I’m just playing my game, just playing hard, relentless on the boards. Whenever I just feel like I get a lot of offensive rebounds, I just know I’m gonna have a good game. I feel like that’s my motor for me to get me going.”

The 24-year-old Claxton missed eight games earlier this season with a high-ankle sprain suffered in the Nets’ season opener against the Cavaliers, but his 2.4 blocked shots per game would rank him in the top 10 in the NBA if he had enough appearances to qualify.

Claxton rejected two shots and Sharpe added another block against the Wizards.

“You know how [valuable] bigs are in the league, especially for your team,” Mikal Bridges said after the Nets totaled 76 points in the paint against the Wizards. “Having those guys anchor defensively helps so much to what we’re doing offensively and being dogs on our offensive boards and defensive boards, and then, punishing mismatches.

“Them just doing what they’re doing, like just rolling hard, defending, rebounding, that’s always what we need from them every day.”

Vaughn added that Claxton and Sharpe have been “pushing each other” in practice, and he wants to continue fostering that competition.

“It’s been really pleasing, just because those two are dudes you really enjoy being around, and for different reasons,” Vaughn said. “For them to grow on both ends of the floor and see the growth, I’ve been with them from the beginning and I get a chance to see and push them and want more from them and they want more from themselves.

“I think that’s huge for their growth. I think they enjoy pushing each other and now there’s some synergy of ‘[I’m going to] pass the baton to you and you’re gonna play your minutes and you’re gonna pass it back to me and we’re gonna try to dominate it from that position.’ ”
