It was expected to be a close game between the fifth and sixth seeded teams in the Western Conference, and the first quarter delivered just that as the Thunder (fifth seed) held a slim two point lead after the first 12 minutes.
Despite being without star guard Damian Lillard for the match, the Trailblazers came right back at OKC with plenty of production from guard CJ McCollum and centre Jusuf Nurkic to hold a four point lead at half time.
It might have been close coming out of the break, but a 21-8 run put the Trailblazers up 81-68 toward the end of the third quarter, with McCollum leading the way. He had 15 points in the quarter and three assists.
It proved to be a game-winning performance as the Thunder couldn't do enough to come back in the final 12 minutes.
The Thunder are now exaclty halfway through their season and hold a 22-19 record, and they won't have to wait long to try improve on that, heading to Minneapolis to face to Minnesota Timberwolves on Thursday (NZT).
