E'Twaun Moore put the Chicago Bulls ahead with just over two seconds remaining to give the side a 108-105 win over the Oklahoma City Thunder at the United Center.
The visitors were ahead early on as Russell Westbrook continued his recent strong run, leading the Thunder to a 12-point advantage by the end of the first quarter.
Nikola Mirotic got the home side back into the game before half time, but Westbrook hit his stride again after the break, scoring 19 of his 43 in the third quarter to keep Oklahoma City ahead.
Mirotic rallied again for Chicago, cutting the lead to just one point inside the final 30 seconds before Westbrook missed a shot, leaving Pau Gasol to win it back for Moore and add a three-pointer in the final moments.
The win moves the Bulls to a 38-23 record, leaving them second in the Eastern Conference, while defeat leaves the Thunder eighth in the West.
