The Mavericks, who have won five in a row and nine of their past 10, also got 18 points, eight rebounds and seven assists from P.J.

The Grizzlies extended their lead to 13 late in the quarter taking advantage of 10 Dallas turnovers in the period. Morant had 11 points in the quarter, including four in the closing eight seconds as Memphis took a 95-82 lead into the fourth. The Grizzlies outscored Dallas 38-22 in the quarter.

The Mavs led for most of the opening half and built a 10-point advantage (48-38) midway through the second quarter after Doncic scored on a leaner from the free-throw line and made the and-one. Doncic had 24 points at the half, including four 3-pointers.

Memphis was up by one (26-25) entering the second quarter, but only led briefly later in the quarter after a 12-0 run gave the Grizzlies a 50-48 advantage. Jaylen Wells capped the run with a 3-pointer, but Dallas closed strong and led 60-57 at the break.

Morant was limited to five points in the opening half. Jackson Jr. paced the Grizzlies with 14 first-half points.
