OKLAHOMA CITY (AP) -- CJ McCollum had 27 points and seven assists, and the Portland Trail Blazers beat the Oklahoma City Thunder 117-106 on Tuesday night in the opener of a four-game trip.
Shabazz Napier added 21 points and Jusuf Nurkic had 20 points and eight rebounds for Portland, which moved past Oklahoma City into second in the Northwest Division standings with its seventh win in its last nine games against the Thunder.
Portland has won four of five overall despite playing most of that stretch without star guard Damien Lillard, who sat out for the seventh time in the last nine games with a left calf strain.
Russell Westbrook had 22 points, 12 assists and nine rebounds for Oklahoma City, which has dropped off after playing well for most of December. The Thunder have dropped four of six, with three of those losses coming at home.
Oklahoma City shot 44 percent from the field while Portland made 53.1 percent of its shots. Paul George scored 22 points for the Thunder, and Carmelo Anthony had 19.
The Thunder closed to 83-76 with 1:39 remaining in the third quarter on a basket by Anthony, but Portland answered with a 13-1 run and led 96-77 after a 3-pointer by Al-Farouq Aminu with 10:25 left.
Trail Blazers: Coach Terry Stotts said he didn't have an update on Lillard's injury, "other than he's out." Napier made his sixth start of the season in Lillard's place. … The Blazers are 12-8 on the road this season. … Portland has scored more than 110 points in five straight games for its longest such stretch this season.
Thunder: Standout defender Andre Roberson missed his fifth straight game with left patellar tendinitis. Coach Billy Donovan said Roberson practiced a bit on Monday and Tuesday but would also miss Wednesday's game at Minnesota. Terrance Ferguson started in Roberson's place for the fourth straight game and went scoreless. … Official Justin Van Duyne called George for a technical foul early in the second quarter for colorfully protesting a no-call after George drew contact on a layup attempt that missed. George responded by scoring 15 points in the final 9:37 of the half. … George hit 5 of 9 3-point attempts and set a Thunder record with at least three 3-pointers in eight straight games.
