Doncic converted a three-point play with 2:19 remaining to put Dallas ahead 118-117 and Kyrie Irving answered Devin Vassell’s two free throws with a 3-pointer with 1:51 to play.

Doncic then stole the ball from Jeremy Sochan and fed Irving for a layup before sinking a 3 of his own with 30 seconds left to give the Mavs a 126-119 lead.

Irving had 22 points and Grant Williams and Tim Hardaway Jr. added 17 apiece.

Vassell led San Antonio with 23 points and Keldon Johnson had 17 with nine rebounds and seven assists.
