Australian Exum started for the Mavericks and scored 11 points on 5-of-8 field-goal shooting, while also dishing up seven assists in front of home fans on Friday night (Saturday AEDT).

Dallas (74-30) won for the 13th time in their past 15 games and solidified their hold on fifth place in the Western Conference, two games clear of seventh in pursuit of one of the six guaranteed playoff spots.

Stephen Curry scored 28 points, including a tying jumper with 13 seconds to go, as Golden State missed a chance to clinch a post-season spot.

In Indianapolis, Australian Josh Giddey finished one rebound short of a triple-double, but his Oklahoma City Thunder were unable to overcome the absence of their injured leading scorers Shai Gilgeous-Alexander (quad) and Jalen Williams (ankle).

After a strong start the Thunder (52-25) fell 126-112 to the impressive Pacers, losing a third straight game for the first time this season and denting their bid for top seed in the Western Conference.

Giddey took on primary play-making duties with Gilgeous-Alexander sidelined and scored 14 points on 6-of-17 shooting from the field, while handing out 12 assists and claiming nine rebounds in his 35 minutes on court.

Lu Dort led Oklahoma City with 22 points and centre Chet Holgren had 15, while Kendrich Williams added 18 from the bench.

"Those are injuries that basically the timetable is dictated by how they respond to the recovery and that whole process," Thunder coach Mark Daigneault said.

"It's a quad contusion (for Gilgeous-Alexander). Jalen's an ankle sprain. We'll let the timetable play out."

In Boston, Payton Pritchard had 21 points, including five three-pointers, as the league-leading Boston Celtics held off a late charge to beat the Sacramento Kings 101-100.
