PORTLAND, Ore. » After two straight losses — one to Utah at home and another to the Los Angeles Clippers the night before — the Oklahoma City Thunder weren’t going to give up against the Portland Trail Blazers.

Shaking off their fatigue, the Thunder overcame a double-digit second-half deficit to beat the Blazers 107-106 in overtime last night.

Kevin Durant and Russell Westbrook each had 28 points and 11 rebounds in the victory.

"We needed it a lot," said Durant. "It’s kind of like a monkey off our back once the buzzer ended it. It’s a good win for us."

LaMarcus Aldridge led the shorthanded Trail Blazers with 22 points and Brandon Roy had 19.

Roy missed two key jumpers at the end of regulation and the Blazers could never catch up after the Thunder pulled ahead in overtime.

James Harden gave the Thunder a 103-100 lead in the extra period with a layup and a free throw. Andre Miller missed a layup for Portland, but Roy hit two free throws with 40.7 seconds left.

Durant missed a jumper from the top of the key and the Blazers couldn’t get the rebound. Nicolas Batum was forced to foul Durant, who hit two free throws with 13.7 seconds to go.

Wesley Matthews’ attempted layup rested on the edge of the rim before falling away, thwarting Portland’s chance at a three-point play. After making one free throw, Westbrook hit two foul shots for the Thunder.

Rookie Armon Johnson made a 3-pointer with 0.1 seconds left for Portland.

"Tough," Matthews said.

The Thunder had struggled on Wednesday night in a 107-92 loss to the Clippers, who held Durant to 16 points. Before that, Oklahoma City was blown out 120-99 at home by Utah.

"That was a big win for us. I just liked the way we competed and stayed with it," Thunder coach Scott Brooks said. "We got down in the first half, but we just chipped away and stayed together and kept fighting and good things happened."

There was a contingent of fans who wore SuperSonics jerseys, including one who hoisted a large sign reading "Homeless" — an obvious bitter rebuke of the Thunder franchise’s move from Seattle to Oklahoma City.

Before the game, Portland center Fabricio Oberto abruptly retired because of a prior cardiac condition that caused heart palpitations.

Oberto, in his sixth year in the NBA, was signed by the Blazers a day before the start of the season to fill in while centers Joel Przybilla and Greg Oden heal from knee surgeries. Oberto experienced dizziness in Portland’s game against Milwaukee on Tuesday.

The Blazers also announced yesterday that rookie guard Elliot Williams would have surgery to repair a dislocated right patella and would likely miss the rest of the season.

And swingman Rudy Fernandez sat out the game with back trouble. That gave the Blazers only 10 healthy players for the game.

KNICKS 120, BULLS 112

Toney Douglas scored a career-high 30 points, and New York made 16 of 24 3-point attempts as New York beat Chicago.

It was an astounding display from the outside for the Knicks after they hit just 29.1 percent over the first three games.

Douglas made five of nine 3s, Danilo Gallinari hit four 3s without a miss and finished with 24 points — all but three in the first half as the Knicks took a 21-point lead in going up 70-52 at halftime.

Raymond Felton was 4-for-6 from long range and finished with 20 points and 10 assists, while Amare Stoudemire added 14 points and eight rebounds for the Knicks.

Chicago’s Derrick Rose had 24 points and 14 assists, but sat out the final 9:31.
