PORTLAND, Ore. - Brandon Roy looked every bit the All-Star Friday night.

Roy had 20 points, 11 rebounds and 10 assists a night after being picked for his first All-Star game, and the Portland Trail Blazers beat the New York Knicks 94-88 in overtime Friday night.

It was Roy’s first career triple-double. Steve Blake added 18 points and LaMarcus Aldridge had 17 points and eight rebounds for Portland, which is 19-5 at the Rose Garden this season.

“We were dead in the water ... and we were able to mount another unbelievable comeback,” Roy said. “It’s a special season.”

Zach Randolph led the Knicks with 25 points and 13 rebounds in his first game in Portland after being traded to New York in June.

Nate Robinson added 17 points, David Lee had 14 points and 15 rebounds, and Jamal Crawford had 13 points on 6-for-27 shooting for the Knicks, who lost their fourth straight on a five-game road trip that ends Saturday in Seattle.

“We couldn’t make a shot,” New York coach Isiah Thomas said. “We just went cold.”

Travis Outlaw tied the game with a step-back 20-footer with 5.6 seconds left in the fourth quarter and Crawford missed a 3 from the top of the key to send the game into overtime.

Outlaw, who had 13 points, put Portland on top 86-85, going past Lee for a dunk, and Jarrett Jack drove for a layup with 46.3 seconds left that gave the Blazers a three-point lead.

Robinson scored quickly on a runner for the Knicks, but Roy tipped in his own miss for Portland. Jack and Roy hit two free throws for the Blazers.

“Offensively we were ragged and we needed our guards, Steve, Brandon and Jarrett to do our scoring,” Blazer coach Nate McMillan said.

The Knicks were playing short-handed when Quentin Richardson and Eddy Curry, suffering from flu-like symptoms, were scratched before the game, joining Stephon Marbury (ankle) on the inactive list.

Randolph started despite arriving just an hour before the game. Fans in the soldout Rose Garden booed Randolph and Thomas during introductions, cheered Portland native and former Blazer Fred Jones and roared for Roy, who is Portland’s first All-Star since Rasheed Wallace in 2001.

Roy, who will also play in rookie game All-Star weekend, was selected as a reserve guard for the Western Conference team, earning the honor over the likes of Golden State’s Baron Davis and Utah’s Deron Williams.

Randolph led the Blazers in scoring and rebounding three of the past four seasons, but they parted with him, Dan Dickau and Jones in a draft day trade for Channing Frye and Steve Francis, in an effort to make room for Aldridge and No. 1 pick Greg Oden.

The move has appeared to be addition by subtraction for Portland, which has jelled around a nucleus that includes leading scorer Roy and leading rebounder Aldridge and entered the contest just 1½ games back in the Northwest Division.

Randolph, who bested his season averages of 17.2 points and 10.4 rebounds, said he was surprised by the boos but “they made me play harder.”

He was disappointed not to leave Portland with a win.

“I would have liked to win this game tonight,” he said. “I like to win all of them but this game would have been special. ... I feel we had this game. It slipped away.”

Thomas canceled practice Thursday to give his weary team a rest. But the Knicks didn’t look sluggish at all, owning a 55-41 rebound advantage and leading by as many as 15 points.

The Blazers hit six of their first seven and led by eight points early, but Robinson gave the Knicks a lift off the bench, scoring 10 in the first quarter.

With Portland struggling through a 4-for-21 stretch, the Knicks took a 36-24 lead.

Randolph’s jumper early in the third gave New York its biggest lead of the game at 57-42, but Portland erased it with a 19-4 run. Roy drove through the key for an unabated dunk to tie it at 61 with 4½ minutes remaining in the third.

Notes: Blazers president Larry Miller took the court at the first timeout, asking fans to recognize Roy and Aldridge, who will play in the rookie game All-Star weekend. They did, with a standing ovation. ... Randolph was philosophical about the prospect of getting booed in Portland. “We get booed at home,” he told reporters Thursday. “How much worse can it get?” ... Problems with the shot clocks stopped play several times in the game, which was televised on ESPN. In the second quarter, a portable clock was wheeled out on the floor at one end.
