Michael Carter-Williams' three-pointer with 5 minutes, 41 seconds remaining gave the Sixers a 93-92 advantage. Then Turner added a three-pointer on the Sixers' next possession to give his team a four-point cushion.
"Mike rebounded, pushed the pace, made the guy - I think it was [Iman] Shumpert - try to play him," Turner said of his corner three-pointer. "He kicked it to me, got me the rock. Drawers! That's it."
After the Knicks pulled within two points, Thaddeus Young hit a three-pointer with 1:47 remaining to give the Sixers a 105-100 lead.
"That, too, was a big three," coach Brett Brown said. "I think Michael's and Evan's came at timely parts of the game."
Turner added a bucket to make it a seven-point game with 1:14 remaining
His performance more than made up for his dismal outing in a 102-92 setback to the Knicks on Jan. 11.
Turner was more aggressive and made his first four shots.
He scored on a 17-foot jumper. The fourth-year player then sandwiched two three-pointers around a 17-footer. He had 18 points in the first half on 7-for-9 shooting. Turner ended up making 13 of 22 shots and finishing with 11 rebounds.
This was a huge difference from when he was limited to just six shots in the first three quarters in the Jan. 11 loss. He finished that game with 12 points on 4-for-11 shooting.
"Coach just told me to be aggressive and get my swagger back," Turner said. "So I was consciously trying to be aggressive. That's pretty much it."
Carter-Williams added 19 points, 12 rebounds, and 7 assists Wednesday.
The Sixers showed drastic improvement over the last three games from three-point land.
They made 9 of 14 three-pointers after making just 8 of 57 combined in consecutive losses to the Miami Heat, Chicago Bulls, and Washington Wizards.
The Sixers took advantage of the absence of Knicks post players Amar'e Stoudemire and Kenyon Martin. Both left with ankle injuries. The Sixers scored 50 points in the paint and had 19 second-chance points and 17 offensive rebounds.
Sixers reserve forward Brandon Davies will be out four to six weeks after having surgery Tuesday on his fractured right little finger. . . . The Sixers are expected to sign center Dewayne Dedmon to a second 10-day contract. . . . Brown said reserve forward Arnett Moultrie (left ankle) could return within the next two weeks. He has yet to play this season.
