Luka Doncic added 13 points, 12 rebounds and 11 assists as Dallas snapped its first three-game losing streak in almost two years.
The short-handed Pacers have lost two straight by double digits, their two most lopsided losses of the season. Malcolm Brogdon had 26 points and Domantis Sabonis finished with 25 points and 10 rebounds, giving him a franchise-record 14 in a row.
Dallas took the lead for good on the final basket of the third quarter and pulled away with an 11-4 run in the fourth.
The Mavericks were in control most of the night after using an early 15-3 run to take a 37-22 lead late in the first quarter.
Indiana closed the deficit to 65-63 at the half, then took its first lead when Edmond Sumner's 3-pointer broke a 67-all tie early in the third. It didn't last long.
Porzingis scored all of the Mavericks points in a 9-2 run and Dallas eventually extended the margin to 84-76.
Again, the Pacers charged back, tying the score at 86 on Brogdon's second 3 of the game, taking an 89-88 lead on his next 3 and then making it 91-88 when Brogdon made a layup.
But Dallas answered with a 13-3 run to make it 101-94 and gradually pulled away late to seal it.

Lamb hadn't played since injuring his left knee Feb. 23, 2020. He was diagnosed with a torn anterior cruciate ligament, a torn medical collateral ligament and a fractured femur — the bone just above the knee. Lamb was perfect in the first half, going 4 of 4 from the field, including one 3 while making his only free throw. He didin't make another shot and finished with 10 points in 19 minutes.
THEY'RE BACK, TOO
