PORTLAND, Ore. >> Damian Lillard called it a breakthrough.

Coming off a one-point loss to the Clippers the night before, the Portland Trail Blazers snapped a four-game losing streak with a 114-95 victory over the Oklahoma City Thunder on Tuesday night.

Lillard had 17 points and nine assists before sitting in the fourth quarter. Mason Plumlee added 18 points for the Blazers, who led by 26 points in Portland’s first game back after a 1-4 road trip.

Russell Westbrook was off his league-leading average of 31.1 points a game with 20 for the Thunder, who have lost two of their last three after a six-game winning streak. Westbrook also sat for the final quarter.

Portland was coming off a 121-120 loss at Los Angeles on Monday night to extend the season’s longest losing streak.

“We had a chance to win that game, but we came up short,” Lillard said about the game against the Clippers. “I think all of those things we went through, and then staying with it, and the build up, tonight felt like kind of a breakthrough from all those experiences.”

The Thunder were without Victor Oladipo because of a right wrist sprain, forcing Oklahoma City’s first starting lineup change of the season. Jerami Grant, acquired by the Thunder in a trade with Philadelphia at the start of the season, got his first start for Oklahoma City and finished with 11 points.

“I didn’t think that we shot the ball particularly well today,” Thunder coach Billy Donovan said. “I thought that we had fairly decent looks, but we didn’t shoot the ball well, and I thought some of that bled into our defense a little bit.”

The Blazers didn’t have Al-Farouq Aminu, who has a sore back, instead starting Noah Vonleh. But Vonleh got into foul trouble, collecting three in the first quarter.

Westbrook’s 3-pointer put the Thunder up 25-16 early, but Portland came back to take a 32-31 lead on Allen Crabbe’s layup before the end of the first quarter. CJ McCollum made a three-quarter court shot, but he didn’t beat the buzzer.

Portland stretched the lead to 50-36 after Evan Turner’s floater and free throw. The two sides exchanged words midway through the second quarter when Lillard reached down to pick up the ball at a timeout and Westbrook kicked it.

Lillard closed out the half with a left-handed layup to make it 68-52. Plumlee’s basket stretched Portland’s lead to 90-65 late in the third quarter.

Plumlee said he didn’t feel Portland went through any lulls.

“Every time they made a 3 or they had two baskets in a row, we would get right back on defense, we would get a good shot on offense so we didn’t let anything get out of control,” he said. “We didn’t let anything snowball.”
