Two nights, two wins over the Oklahoma City Thunder. The Portland Trail Blazers are starting to look like a real problem.

Deni Avdija scored 28 points and Portland beat the Thunder 118-108 at Moda Center on Wednesday night. It came one night after the Blazers beat Oklahoma City 123-103 on the same floor.

Avdija also had six assists, four steals and two blocks. He made all six of his free throws.

A tight fourth quarter

Portland led by 12 in the third quarter. The Thunder came all the way back. Nique Clifford tied it at 88 with a 3-pointer early in the fourth and Oklahoma City soon took its first lead since the first half.

Avdija and Damian Lillard took over from there. The two combined for 20 of Portland's 30 points in the fourth quarter.

Avdija put the Blazers back in front 99-98 with two free throws with 5:24 left. He hit a 3-pointer with 2:53 to go. Lillard followed with a floater, a driving layup and two free throws to keep the Thunder at arm's length.

Then Avdija finished it. He stole the ball from Isaiah Hartenstein and ran in for a dunk that made it 116-106 with 36.5 seconds left.

Help all over the floor

Sidy Cissoko scored 19 points on 6-of-9 shooting. Jrue Holiday added 19 off the bench with five 3-pointers. Lillard finished with 18 points. Donovan Clingan grabbed 12 rebounds and blocked three shots.

The Blazers made 19 3-pointers and went 25 of 26 at the free-throw line.

Portland had lost 19 of its previous 20 games against Oklahoma City before this week.

Thunder drop two straight

Shai Gilgeous-Alexander scored a game-high 31 points, 23 of them after halftime. He made 13 of 14 free throws. Hartenstein had a season-high 20 points with 11 rebounds.

Portland improved to 8-3. Oklahoma City fell to 8-4. The Thunder visit the Los Angeles Clippers on Friday night. The Blazers play at Sacramento the same night.
