Second string leads Nets to victory over Wizards

If the Nets could have completely taken Tuesday night off instead of playing the Wizards, they would have.

Instead, after Sunday’s loss in Toronto locked them into the fourth seed in the Eastern Conference playoffs — and into a matchup this weekend with either the Hawks or Bulls (Atlanta holds a one-half game lead with two games left to one for Chicago) — the Nets instead took the occasion to rest virtually all of their key contributors.

In fact, the entire starting five from Sunday’s game — Deron Williams (left knee contusion), Joe Johnson (sore left heel), Keith Bogans (tight lower back), Reggie Evans (sore left shoulder) and Brook Lopez (mid back contusion) — got a chance to rest, along with Jerry Stackhouse (stiff neck). The backups still managed to come away with a

106-101 win over the Wizards in front of a crowd of 16,774 at Barclays Center.

“We’ve got some guys that … if we had won and were still having a possibility for the third seed … probably would not have played because it’s back-to-back, and we had some other guys that just got hit,” Nets interim coach P.J. Carlesimo said. “Deron’s one of them.

Deron, between Indiana [Friday] and Toronto got hit about 19 times, so it might’ve just been prudent to not play him anyhow.

“It’s really a combination of the back-to-back, the playoffs on the weekend and the fact that we can’t go up or down right now, but the injuries are a little more of a factor than just flat-out resting them.”

Carlesimo added he hoped to get most, if not all, of the players who sat out of Tuesday’s game at least some work in Wednesday’s season finale against the Pistons in Brooklyn.

“That’s the plan,” he said. “If they’re healthy, we want to play them.

They’re not going to play 40 minutes, but we’ve been saying all along … they could get hurt in practice Thursday or Friday, too, so they’ve got to be sharp and they’ve got to be playing.”

In a bit of a surprise, the Nets (48-33) did see one of their main players, small forward Gerald Wallace, return to the starting lineup after sitting out the previous two games with a lower left leg contusion he suffered in a win over the Celtics in Boston on April 9.

“We’ve got to see how he comes back, but we need to get him back in the flow,” Carlesimo said of Wallace, who finished with two points and two assists in 23 minutes. “We saw a dramatic evidence of how much we miss him on Sunday [against Toronto], so we need to find out where he’s at. He’s still got a couple days [to rest] before the weekend, but hopefully he can play pain free, or relatively pain free … and maybe we can get some minutes out of him [Wednesday] also.

“We’ve just got to start to bring him back and get him ready for the weekend.”

With so many players sitting out, Tuesday’s game was a chance for some seldom-used players on the roster to shine. Playing against his former team, Andray Blatche led the Nets with 20 points and 12 rebounds, while Kris Humphries had 20 points and nine boards.

Rookies Tornike Shengelia and Tyshawn Taylor also had big impacts on the game. Shengelia finished with 11 points and 11 rebounds and helped the Nets surge ahead in the fourth quarter, while Taylor finished with

14 points, including a 3-pointer with 22 seconds left to ice the game.
